Treatment of multisite, sclerotic bone metastases is successfully performed by radionuclide therapy. Pain palliation is the most common aim for the treatment. Two radiopharmaceuticals are currently approved by the European Medicines Agency (153Sm-EDTMP and 89Sr-Cl2) whilst other radiopharmaceuticals are at different stages of development, or are approved in some European countries (186Re-HEDP, 117Snm-DTPA and 223Ra-Cl2). The tissues at risk for the treatment are bone marrow and normal bone. A review of the methods applied for dosimetry for these tissues and for tumours is performed, including the calculation of S values (the absorbed dose per decay) and optimal procedures on how to obtain biodistribution data for each radiopharmaceutical. The dosimetry data can be used to individualise and further improve the treatment for each patient. Dosimetry for radionuclide therapy of bone metastases is feasible and can be performed in a routine clinical practice.. ...

The phantom was filled with an exact known FDG stock solution (aimed at 40 kBq/mL). Each scan was reconstructedusing various clinically relevant reconstruction settings. Depending on PET/CT system reconstruction settings were varied as follows: time of flight (TOF) ...
Red blood cells (RBCs) labeled with single-photon emitters have been clinically used for blood-pool imaging. Although some PET tracers have been introduced for blood-pool imaging, they have not yet been widely used. The present study investigated the feasibility of labeling RBCs with 18F-2-deoxy-2-fluoro-D-glucose (18F-FDG) for blood-pool imaging with PET. RBCs isolated from venous blood of rats were washed with glucose-free phosphate-buffered saline and labeled with 18F-FDG. To optimize labeling efficiency, the effects of glucose deprivation time and incubation (labeling) time with 18F-FDG were investigated. Post-labeling stability was assessed by calculating the release fraction of radioactivity and identifying the chemical forms of 18F in the released and intracellular components of 18F-FDG-labeled RBCs incubated in plasma. Just after intravenous injection of the optimized autologous 18F-FDG-labeled RBCs, dynamic PET scans were performed to evaluate in vivo imaging in normal rats and intraabdominal
A system and method for performing quantitative lesion analysis in molecular breast imaging (MBI) using the opposing images of a slightly compressed breast that are obtained from the dual-head gamma camera. The method uses the shape of the pixel intensity profiles through each tumor to determine tumor diameter. Also, the method uses a thickness of the compressed breast and the attenuation of gamma rays in soft tissue to determine the depth of the tumor from the collimator face of the detector head. Further still, the method uses the measured tumor diameter and measurements of counts in the tumor and background breast region to determine relative radiotracer uptake or tumor-to-background ratio (T/B ratio).

Due to the high mortality of lung cancer, there is a critical need to develop diagnostic procedures enabling early detection of the disease while at a curable stage. Targeted molecular imaging builds on the positive attributes of positron emission tomography/computed tomography (PET/CT) to allow for a noninvasive detection and characterization of smaller lung nodules, thus increasing the chances of positive treatment outcome. In this study, we investigate the ability to characterize lung tumors that spontaneously arise in a transgenic mouse model. The tumors are first identified with small animal CT followed by characterization with the use of small animal PET with a novel 64Cu-1,4,7,10-tetra-azacylododecane-N,N,N,N-tetraacetic ...

Well, I had one of those long deep heart-to-heart meetings with my chemo oncologist yesterday to review Mondays CT/PET scan results and try and come up with a new strategy. The GOOD news of the scan is that the cancer hasnt invaded any new organs. The bad news is that my liver mets have really taken off in the last 2 months and it looks like at least half of my liver is involved now. It was hard to look at the scan pictures as we scrolled through, with the scan from 2 months ago, side-by-side, and see how much my cancer has grown in just 2 months even though I was on Avastin/Cytoxin all that time. We reviewed the chemo drugs I havent had yet. Most of the approved endometrial cancer drugs left to me are older ones that they dont use unless they have to because they are too harsh or less effective; and the rest of my "targeted inhibitor" options are all super new and reletively unproven for uterine cancer. And we frankly agreed that my cancer appears to be completely chemo resistant. I made it ...

BACKGROUND: Inflammation plays a key role in progression and destabilization of atherosclerotic plaque. [18F]-fluorodeoxyglucose positron emission tomography (18FDG-PET) is a promising tool for visualizing inflammation of atherosclerotic plaque. Anti-inflammatory action is one of the pleiotropic effects of statins.. OBJECTIVE: We investigated whether simvastatin attenuates plaque inflammation by using 18FDG-PET co-registered with computed tomography.. METHODS and RESULTS: Forty-three consecutive subjects, who underwent 18FDG-PET for cancer screening and had 18FDG uptakes in the thoracic aorta and/or the carotid arteries, were randomized to either statin group receiving simvastatin (n=21) or diet group receiving dietary managements (n=22). The maximum standardized uptake values (SUVs) were measured in individual plaques, and were averaged for analysis of the subject-wise results. The responses were assessed after 3-month treatments. PET revealed 117 and 123 18FDG-positive plaques in the statin ...

A proportion of patients with pancreatic cancer never develop metastatic disease. We evaluated a role for (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) in identifying a subset of patients with locally advanced pancreatic cancer (LAPC) who never develop metastatic disease and only experience local disease and may therefore benefit from local treatment intensification.
It has been well established that hepatocellular carcinomas (HCCs) accumulate [[sup 18]F]fluorodeoxy-glucose (FDG) to varying degrees; this is thought to be due to differing amounts of FDG-6-phosphatase activity. The purpose of this study was to evaluate the impact of FDG imaging on the management of patients diagnosed with hepatocellular carcinoma. We conducted a retrospective review of the clinical data of 91 consecutive patients diagnosed with HCC who underwent FDG-positron emission tomography (PET) imaging between August 1993 and March 2001. The patients were divided into two groups. In Group one 67 of 91 (74%) patients were evaluated for proven but untreated hepatic lesions using PET. In Group two the remaining 24 patients (26%) were referred for evaluation of HCC recurrence but did not have prior PET. The FDG images were acquired with two dedicated PET tomographs [Siemens ECAT 933, CTI (Knoxville, TN) and GE Advance, General Electric Medical Systems (Milwaukee, WI)] one hour after the ...

Despite the growing use of [18F]-FDG PET imaging in oncology (9, 10), limited data exist regarding its use in monitoring treatment response and predicting survival in advanced TETs (11, 19-31). With a few exceptions (25, 27, 28, 30), most studies in this area have been retrospective, involving small sample sizes and inconsistent measures of [18F]-FDG uptake. Furthermore, the majority of the studies have an overrepresentation of thymoma compared with thymic carcinoma. There is limited information on its role in monitoring treatment response and as a predictor of survival (20, 23), and we are not aware of prospective systematic studies addressing these questions.. As a retrospective analysis of prospectively collected data, this study shows that in patients with advanced or recurrent TETs: (i) effective treatment with chemotherapy or targeted therapy causes rapid reduction in [18F]-FDG uptake, (ii) early metabolic response predicts eventual RECIST response and is associated with improved PFS, and ...

Background: The aim of our study is to establish the potential role of dual-phase F-fluorodeoxyglucose positron emission tomography / computed tomography (FDG-PET/CT) in patients presenting ovarian masses with diffuse peritoneal infiltration for differentiating benign from malignant lesions. Methods: Twenty patients (13 with ovarian cancers and 7 with benign lesions) were evaluated preoperatively by dual-phase F-FDG-PET/CT performed 1 h and 2 h after injection of F-FDG. The maximum standardized uptake value (SUVmax) for both time points SUVmax1 and SUVmax2 were determined, respectively, and the retention index (RI) was calculated by subtracting the SUVmax1 from the SUVmax2 and dividing by SUVmax1. Results: The areas under the receiver operating characteristic curves (AUCs) of SUVmax1 and SUVmax2 were 0.753 (P = 0.062, 95% confidence interval [CI] = 0.512-0.915) and 0.835 (P = 0.001, 95% CI = 0.604-0.961), respectively. The AUC of the RI was 0.901 (P | 0.001, 95% CI = 0.684-0.988). Using pairwise

Purpose. The main objective of this study was to evaluate the prognostic value of volumetric and metabolic information derivied from F-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) in combination with computed tomography (CT) prior to liver transplantation (LT) in patients with nonresectable colorectal liver metastases (CLM). Due to scarcity of liver grafts, prognostic information enabling selection of candidates who will gain the highest survival after LT is of vital importance. 18F-FDG PET/CT was a part of the preoperative study protocol. Patients without evidence of extrahepatic malignant disease on 18F-FDG PET/CT who also fulfilled all the other inclusion criteria underwent LT.. Methods. The preoperative 18F-FDG PET/CT examinations of all patients included in the SECA (secondary cancer) study were retrospectively assessed. Maximum, mean and peak standardized uptake values (SUVmax, SUVmean and SUVpeak), tumor to background (T/B) ratio, metabolic tumor volume (MTV) and total ...
BACKGROUND: To evaluate [(18)F]-2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET), for early evaluation of response to palliative chemotherapy and for prediction of long-term outcome, in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS: In a randomized trial, patients with mCRC received irinotecan-based combination chemotherapy. FDG-PET was carried out before treatment and after two cycles in 51 patients at two centers. Visual changes in tumor FDG uptake and changes measured semi-automatically, as standard uptake values (SUVs), were compared with radiological response after four and eight cycles. RESULTS: The mean baseline SUV for all tumor lesions per patient was higher in nonresponders than in responders (mean 7.4 versus 5.6, P = 0.02). There was a strong correlation between metabolic response (changes in SUV) and objective response (r = 0.57, P = 0.00001), with a sensitivity of 77% and a specificity of 76%. There was no significant correlation between ...

Prostate cancer is a common cancer in men and continues to be a major health problem. Imaging plays an essential role in the clinical management of patients. An important goal for prostate cancer imaging is more accurate disease characterization through the synthesis of anatomic, functional, and molecular imaging information. Developments in imaging technologies, specifically magnetic resonance imaging (MRI) and positron emission tomography (PET)/computed tomography (CT), have improved the detection rate of prostate cancer. MRI has improved lesion detection and local staging. Furthermore, MRI allows functional assessment with techniques such as diffusion-weighted MRI, MR spectroscopy, and dynamic contrast-enhanced MRI. The most common PET radiotracer, (18)F-fluorodeoxyglucose, is not very useful in prostate cancer. However, in recent years other PET tracers have improved the accuracy of PET/CT imaging of prostate cancer. Among these, choline (labeled with (18)F or (11)C), (11)C-acetate, and ...

In diabetic cardiomyopathy, left ventricular (LV) diastolic dysfunction is one of the earliest signs of cardiac involvement prior to the definitive development of heart failure (HF). We aimed to explore the LV diastolic function using electrocardiography (ECG)-gated \(^{18}\)F-fluorodeoxyglucose positron emission tomography (\(^{18}\)F-FDG PET) imaging beyond the assessment of cardiac glucose utilization in a diabetic rat model. ECG-gated \(^{18}\)F-FDG PET imaging was performed in a rat model of type 2 diabetes (ZDF fa/fa) and ZL control rats at age of 13 weeks (n=6, respectively). Under hyperinsulinemic-euglycemic clamp to enhance cardiac activity, \(^{18}\)F-FDG was administered and subsequently, list-mode imaging using a dedicated small animal PET system with ECG signal recording was performed. List-mode data were sorted and reconstructed into tomographic images of 16 frames per cardiac cycle. Left ventricular functional parameters (systolic: LV ejection fraction (EF), heart rate (HR) vs. ...
Distribution: In four healthy male volunteers, receiving an intravenous administration of 30 seconds in duration, the arterial blood level profile for Fludeoxyglucose F 18 decayed triexponentially. The effective half-life ranges of the three phases were 0.2-0.3 minutes, 10-13 minutes with a mean and standard deviation (STD) of 11.6 (±) 1.1 min, and 80-95 minutes with a mean and STD of 88 (±) 4 min.. Plasma protein binding of Fludeoxyglucose F 18 has not been studied.. Metabolism: Fludeoxyglucose F 18 is transported into cells and phosphorylated to [18F]- FDG-6- phosphate at a rate proportional to the rate of glucose utilization within that tissue. [F 18]-FDG-6-phosphate presumably is metabolized to 2-deoxy-2-[F 18]fluoro-6- phospho-D-mannose([F 18]FDM-6-phosphate).. Fludeoxyglucose F 18 Injection USP may contain several impurities (e.g., 2-deoxy-2-chloro-D-glucose (ClDG)). Biodistribution and metabolism of ClDG are presumed to be similar to Fludeoxyglucose F 18 and would be expected to result ...

The combination of lapatinib (Tykerb) and trastuzumab (Herceptin) is active and well-tolerated when given to patients with human epidermal growth factor receptor 2-positive (HER2) metastatic breast cancer (MBC) who have received up to two lines of therapy for advanced disease, a nonrandomized phase II study now shows.. "Whats more, early metabolic imaging by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) appears to provide the key to selecting patients who can be treated with targeted regimens and spared the toxicity of chemotherapy, Nancy U. Lin, MD, Susan F. Smith Center for Womens Cancers, Dana-Farber Cancer Institute, Boston, Ma., and colleagues report online in the Journal of Clinical Oncology.. " Because the number of treatment options and their cost for patients with HER2-positive breast cancer continues to increase, a key question is how best to tailor therapies to individual patients, said Lin. In the metastatic setting, predictive tests ...
While the spectral response of gliomas (7, 8, 14, 16, 17) and normal nervous tissue (18-20) to ionizing radiation has been addressed by a number of investigators, many of these studies were done with single-voxel techniques, which suffer from poor spatial resolution, lack of sampling of multiple regions, and partial-volume effects. The results reported from these studies generally concur with those measured in the present investigation: a reduction in Cho in cases showing a response to therapy and an increase in Cho and a decrease in NAA in areas of recurrent tumor. However, single-voxel approaches lack the spatial sampling necessary to assess the distribution of tumor metabolite levels relative to the radiation target both before and after treatment. Fluorodeoxyglucose positron emission tomography (FDG-PET) is an alternative imaging method for the study of irradiated brain tumors, but it is an expensive technique that requires alignment with a CT or MR examination to permit correlation with ...

Electron beam computed tomography. All of the tests listed are useful in assessing for viable myocardium, except for electron beam computed tomography. Rest-rest thallium, persantine sestamibi, and dobutamine echocardiography are relatively equivalent in sensitivity (approximately 80%). Fluorodeoxyglucose positron emission tomography, which identifies ischemic myocardium by its preferential metabolism of glucose rather than free fatty acids, is thought to be slightly more sensitive and specific in identifying viable myocardium. Recommendations regarding the optimal test depend on the expertise of the individual clinician s institution. Although the surgeons may be reassured by the presence of viable myocardium, because it is associated with better survival and lower perioperative mortality, thoughtful consideration must be paid to the individual patient, because no test is 100% predictive. Recent data reveal that even in the absence of traditionally defined evidence of viability, survival may be ...
Methods We retrospectively investigated 16 TA patients who had FDG-PET or PET/CT scans (total 76 scans) from 2004 to 2012 (all female, 39.1 ± 19.7 years). FDG accumulations in aortic wall lesions of TA was evaluated by semi-quantitative index; the standardized uptake value (SUV). In addition to SUVmax in the aortic wall, we also calculated SUV ratio of maximum aortic wall uptake to mean lung uptake (SUVratio Lu), SUV ratio of maximum aortic wall uptake to mean liver uptake (SUVratio Li), and SUV ratio of maximum aortic wall uptake to mean aortic blood pool uptake (SUVratio BP). We analyzed the relationships of these SUV parameters with the disease activity, which was defined by the level of CRP. We also determined the cutoff levels, sensitivity, and specificity of 4 sets of SUVs (SUVmax, SUVratio Lu, SUVratio Li, and SUVratio BP) for CRP based disease activity by using Receiver Operating Characteristic (ROC) analysis. Moreover, we compared the correlation of these 4 parameters and CRP.. ...
Purpose: Dabrafenib is a selective, potent ATP-competitive inhibitor of the BRAFV600-mutant kinase that has demonstrated efficacy in clinical trials. We report the rationale for dose selection in the first-in-human study of dabrafenib, including pharmacokinetics, tissue pharmacodynamics, 18F-labelled fluorodeoxyglucose-positron emission tomography (FDG-PET) pharmacodynamics, and dose-response relationship. Methods: Dabrafenib was administered orally once, twice (BID), or three times (TID) daily. Selected dose cohorts were expanded to collect adequate data on safety, pharmacokinetics, or pharmacodynamics. A recommended phase 2 dose (RP2D) was chosen based on safety, pharmacokinetic, pharmacodynamic, and response data. Results: 184 patients were enrolled and treated with doses ranging from 12mg once daily to 300mg BID in 10 cohorts. Pharmacokinetic assessment of dabrafenib demonstrated a less-than-dose-proportional increase in exposure after repeat dosing above 150mg BID. Similar to parent drug ...

METHODS: Forty oncological patients, BC diagnosed by biopsy, with breast tumor mass diameter >1 cm measured to the mammography, designed for surgical intervention, underwent a pretherapy semi-quantitative 18F-FDG positron emission tomography/computed tomography (18F-FDG PET/CT) whole-body study for tumor staging. Mean Body-Weight Standardized Uptake Value with Correction for Partial Volume effect (PVC- SUVBW-mean) was calculated in all mammary detected lesions. Excised tissues from primitive BC were sectioned and classified according to the WHO guidelines, evaluating biological features. Univariate (Mann-Withney/Kruskal-Wallis) and multivariate (linear regression, hierarchical clustering) statistical tests were performed between PVC-SUVBW-mean and biological indexes. ROC analysis was performed. PVC-SUVBW-mean thresholds were derived allowing to distinguish groups of BC patients with different biological characteristics. Specificity and Sensitivity were also calculated ...

We studied the distribution and expression of translocator protein in the human brain using 11C-[R]-PK-11195 positron emission tomography (PK11195 PET) and evaluated age-related changes. A dynamic PK11195 PET scan was performed in 15 normal healthy adults (mean age: 29 ±8.5 years (range: 20 to 49); 7 males) and 10 children (mean age: 8.8 ±5.2 years (range: 1.2 to 17); 5 males), who were studied for potential neuroinflammation but showed no focally increased PK11195 binding. The PET images were evaluated by calculating standard uptake values and regional binding potential, based on a simplified reference region model, as well as with a voxel-wise analysis using statistical parametric mapping. PK11195 uptake in the brain is relatively low, compared with the subcortical structures, and symmetrical. The overall pattern of PK11195 distribution in the brain does not change with age. PK11195 uptake was lowest in the frontal-parietal-temporal cortex and highest in the pituitary gland, midbrain, thalamus,
The present study clearly showed that the mean SUV T/N ratio obtained with 11C-methionine PET was significantly higher in OT without 1p/19q deletion than in those with this chromosomal aberration. The T/N ratio cut-off values of 2.54 for grade II tumours and 3.63 for grade III tumours will be important in daily clinical practice, in combination with other imaging modalities to predict tumour grade. In tumours categorised as the same histological type and grade, the T/N ratio was significantly different according to the presence or absence of this genetic alteration. Generally, 1p/19q deletion is found in 60-90% of OT,3 and the presence of these deletions is correlated with good chemosensitivity and longer survival, especially in grade III tumours.10 Although it is reported that 1p/19q deletion is exclusively associated with p53 overexpression or unmethylated MGMT,8 ,9 few biological features are linked to this chromosomal aberration. The lower rate of IDH1 mutation in anaplastic OT without ...

A positron emission tomography (PET) scan is a type of nuclear medicine imaging test. It is used to examine various body tissues to identify certain conditions by looking at blood flow, metabolism, and oxygen use. PET scans may also be used to see how well the treatment of certain diseases is working.. For a PET scan, a tiny amount of a radioactive substance, called a radioactive tracer is used to show the metabolism of a particular organ or tissue. This test gives the healthcare provider information about the function and structure of the organ or tissue. It also gives information about its biochemical properties. A PET scan may detect biochemical changes in an organ or tissue that are signs of a disease process before physical changes related to the disease can be seen with other imaging tests. These include computed tomography (CT) or magnetic resonance imaging (MRI).. PET scans are often done along with CT scans (called a PET/CT scan) to give more definitive information about metabolism ...

18F-N-[3-bromo-4-(3-fluoro-propoxy)-benzyl]-guanidine (18F-LMI1195) is a new class of PET tracer designed for sympathetic nervous imaging of the heart. The favorable image quality with high and specific neural uptake has been previously demonstrated in animals and humans, but intracellular behavior is not yet fully understood. The aim of the present study is to verify whether it is taken up in storage vesicles and released in company with vesicle turnover. Both vesicle-rich (PC12) and vesicle-poor (SK-N-SH) norepinephrine-expressing cell lines were used for in vitro tracer uptake studies. After 2 h of 18F-LMI1195 preloading into both cell lines, effects of stimulants for storage vesicle turnover (high concentration KCl (100 mM) or reserpine treatment) were measured at 10, 20, and 30 min. 131I-meta-iodobenzylguanidine (131I-MIBG) served as a reference. Both high concentration KCl and reserpine enhanced 18F-LMI1195 washout from PC12 cells, while tracer retention remained stable in the SK-N-SH cells. After

Complexes useful as radiopharmaceuticals contain the .sup.99m Tc-NO moiety and up to four organic ligands which confer biological target-seeking properties on the complex. Preferred are mono-cationic complexes, particularly having the formulawhere X is halide or pseudohalide and L is a bidentate ligand for Technetium, which have interesting properties for use as heart visualizing agents. Examples of ligands include di-(dialkyl and diphenyl)phosphinoethanes and o-phenylenebisdimethylarsine. The complexes may be made by reacting generator eluate pertechnetate with a hydroxylamine salt and with the ligands, preferably in a single step by providing a reaction mixture containing the three reagents optionally in the presence of a reducing agent.
The semi-quantitative estimate standardised uptake value ratios (SUVR) correlate well with specific binding of the tracer expressed as distribution volume ratios (DVR) for the tau positron emission tomography tracer [18F]AV-1451 uptake and are therefore widely used as proxy for tracer binding. With regard to tracer kinetic modelling, there exists a time point when SUVR deviates minimally from DVR, occurring when the specific binding reaches a transient equilibrium . Here, we have investigated whether the time to equilibrium affects the agreement between SUVR and DVR across different brain regions. We show that the time required to reach equilibrium differs across brain regions, resulting in region-specific biases. However, even though the 80-100 min post-injection time window did not show the smallest bias numerically, the disagreement between SUVR and DVR varied least between regions during this time. In conclusion, our findings suggest a regional component to the bias of SUVR related to the ...

Ahead of a PET (positron emission tomography) scan, you can be injected with a little volume of a glucose (sugar) Option containing some radioactive materials. Youre going to be questioned to relaxation for 30-sixty minutes though the answer spreads through Your system. Your body will then be scanned for top levels of radioactive glucose. Most cancers cells display up brighter to the scan mainly because they take in much more of your glucose Alternative than ordinary cells do. It may well have a few several hours to organize for a PET scan, although the scan itself ordinarily takes about a person hour ...

An imaging technique that uses small quantities of a radioactive tracer similar to sugar (18Fluorodeoxyglucose) to produce images showing how your body is functioning. PET visualises active tissue and cells as opposed to the bodys anatomy and structure. You will be injected with a non-harmful radioactive tracer that acts like glucose and travels all around the body. This tracer collects in active areas of your body, such as cancer cells and is imaged using a PET scanner. PET is primarily used in imaging cancer and can provide doctors with useful information at many stages of the disease process, such as diagnosis, staging or treatment evaluation. Applications for PET in cardiology and neurology are also on the increase. ...
I had two appointments on Friday, one with my oncologist and the second with my radiation oncologist. Earlier in the week, Id had a PET scan and an MRI.. In case youre not familiar with how a positron emission tomography (PET) scan works, the first step is an IV injection of radioactive glucose. I brought Cryptonomicon to keep me company during the hour of waiting for my body to absorb the glucose. Then I dozed off in the scanner as it detected any areas where the glucose collected abnormally. Abnormal uptake can indicate cancer cells, but also areas of radiation damage or inflammation.. My oncologist ordered the PET scan after seeing numerous lesions on my bone scan in June. The PET imaging report also revealed multiple bone and spine lesions but noted that they showed a"relatively low level of uptake." This suggests that the bone mets are stable, at least for now. There was also a bit of activity seen in my lymph nodes and the left breast. All the other organs read as clear or "unremarkable ...
