Radiotherapy where cytotoxic radionuclides are linked to antibodies in order to deliver toxins directly to tumor targets. Therapy with targeted radiation rather than antibody-targeted toxins (IMMUNOTOXINS) has the advantage that adjacent tumor cells, which lack the appropriate antigenic determinants, can be destroyed by radiation cross-fire. Radioimmunotherapy is sometimes called targeted radiotherapy, but this latter term can also refer to radionuclides linked to non-immune molecules (see RADIOTHERAPY).
The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy).

(McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Tomography, Emission-Computed, Single-Photon
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Effect of intravenous dextran 70 and pneumatic leg compression on incidence of postoperative pulmonary embolism. (1/1315)The incidence of pulmonary embolism and deep vein thrombosis was measured in 50 matched pairs of patients undergoing common surgical procedures with preoperative and postoperative ventilation-perfusion lung scans and the fibrinogen uptake test. One patient in each pair was treated with intravenous dextran 70 and pneumatic leggings. The incidence of pulmonary embolism among the treated patients was significantly reduced from 24% to 8%, but the incidence of deep vein thrombosis was not significantly reduced (34% to 24%). (+info)
Rational sequence of tests for pancreatic function. (2/1315)Of 144 patients with suspected pancreatic disease in whom a 75Se-selenomethionine scan was performed, endoscopic retrograde pancreatography (ERP) was successful in 108 (75%). The final diagnosis is known in 100 patients and has been compared with scan and ERP findings. A normal scan reliably indicated a normal pancreas, but the scan was falsely abnormal in 30%. ERP distinguished between carcinoma and chronic pancreatitis in 84% of cases but was falsely normal in five patients with pancreatic disease. In extrahepatic biliary disease both tests tended to give falsely abnormal results. A sequence of tests to provide a rapid and reliable assessment of pancreatic function should be a radio-isotope scan, followed by ERP if the results of the scan are abnormal, and a Lundh test if the scan is abnormal but the findings on ERP are normal.

Bruits, ophthalmodynamometry and rectilinear scanning on transient ischemic attacks. (3/1315)One hundred seventeen patients with clinical signs and symptoms of transient ischemic attacks (TIAs) were evaluated. All underwent clinical evaluation for bruit, ophthalmodynamometry, rapid sequence scintiphotography with rectilinear scanning and four-vessel cerebral angiography. The results of these tests were compared for reliability in predicting location of lesions causing transient ischemic attacks. Angiography remains the most accurate procedure in evaluating extracranial vascular lesions. When determination of bruits, ophthalmodynamometry and brain scanning are done together, accuracy is greater than when any one of the procedures is done alone. (+info)
Gallium-67 scintigraphy and intraabdominal sepsis. Clinical experience in 140 patients with suspected intraabdominal abscess. (4/1315)In 140 patients with suspected intraabdominal abscess, studies were made using gallium-67 citrate and technetium-99m labeled radiopharmaceuticals. Gallium-67 scintigrams correctly localized 52 of 56 intraabdominal abscesses confirmed at surgical operation or necropsy. In an additional 20 patients in whom findings on scintigrams were abnormal, there were clinically established infections. Sixty-one patients in whom findings on scintigrams were normal were conservatively managed and discharged from the hospital; none proved to have an abscess. Four false-negative and three false-positive studies were recorded. Gallium-67 scintigraphy is a useful noninvasive diagnostic adjunct that should be employed early in the evaluation of patients with suspected intraabdominal sepsis. (+info)
Distribution of yttrium 90 ferric hydroxide colloid and gold 198 colloid after injection into knee. (5/1315)Thirteen knees were injected with yttrium 90(90Y) ferric hydroxide colloid, and 12 with gold 198(198Au) colloid for treatment of persistent synovitis. Retention in the knee and uptake in lymph nodes and liver were measured by a quantitative scanning technique. There was no significant difference in the retention in the knee of the two different colloids. A tendency towards higher lymph node uptake was observed with 198Au compared with 90y. The inflammatory activity of the knee at the time of treatment may have influenced the subsequent lymph node uptake of 198Au, but not that of the 90Y, nor the overall leakage of either from the knee. 90Yferric hydroxide colloid was retained in the treated knee at least as well as other colloids which have been used for this purpose.

Economics of myocardial perfusion imaging in Europe--the EMPIRE Study. (6/1315)BACKGROUND: Physicians use myocardial perfusion imaging to a variable extent in patients presenting with possible coronary artery disease. There are few clinical data on the most cost-effective strategy although computer models predict that routine use of myocardial perfusion imaging is cost-effective. OBJECTIVES: To measure the cost-effectiveness of four diagnostic strategies in patients newly presenting with possible coronary artery disease, and to compare cost-effectiveness in centres that routinely use myocardial perfusion imaging with those that do not. METHODS: We have studied 396 patients presenting to eight hospitals for the diagnosis of coronary artery disease. The hospitals were regular users or non-users of myocardial perfusion imaging with one of each in four countries (France, Germany, Italy, United Kingdom). Information was gathered retrospectively on presentation, investigations, complications, and clinical management, and patients were followed-up for 2 years in order to assess outcome. Pre- and post-test probabilities of coronary artery disease were computed for diagnostic tests and each test was also assigned as diagnostic or part of management. Diagnostic strategies defined were: 1: Exercise electrocardiogram/coronary angiography, 2: exercise electrocardiogram/myocardial perfusion imaging/coronary angiography, 3: myocardial perfusion imaging/coronary angiography, 4: coronary angiography. Primary outcome measures were the cost and accuracy of diagnosis, the cost of subsequent management, and clinical outcome. Secondary measures included prognostic power, normal angiography rate, and rate of angiography not followed by revascularization. RESULTS: Mean diagnostic costs per patient were: strategy 1: 490 Pounds, 2: 409 Pounds, 3: 460 Pounds, 4: 1253 Pounds (P < 0.0001). Myocardial perfusion imaging users: 529 Pounds, non-users 667 Pounds (P = 0.006). Mean probability of the presence of coronary artery disease when the final clinical diagnosis was coronary artery disease present were, strategy 1: 0.85, 2: 0.82, 3: 0.97, 4: 1.0 (P < 0.0001), users 0.93, non-users 0.88 (P = 0.02), and when coronary artery disease was absent, 1: 0.26, 2: 0.22, 3: 0.16, 4: 0.0 (P < 0.0001), users 0.21, non-users 0.20 (P = ns). Total 2-year costs (coronary artery disease present/absent) were: strategy 1: 4453 Pounds/710 Pounds, 2: 3842 Pounds/478 Pounds, 3: 3768 Pounds/574 Pounds, 4: 5599 Pounds/1475 Pounds (P < 0.05/0.0001), users: 5563 Pounds/623 Pounds, non-users: 5428 Pounds/916 Pounds (P = ns/0.001). Prognostic power at diagnosis was higher (P < 0.0001) and normal coronary angiography rate lower (P = 0.07) in the scintigraphic centres and strategies. Numbers of soft and hard cardiac events over 2 years and final symptomatic status did not differ between strategy or centre. CONCLUSION: Investigative strategies using myocardial perfusion imaging are cheaper and equally effective when compared with strategies that do not use myocardial perfusion imaging, both for cost of diagnosis and for overall 2 year management costs. Two year patient outcome is the same. (+info)
Incidence of deep vein thrombosis and leg oedema in patients with strokes. (7/1315)In a series of 26 patients with strokes 13 had deep vein thrombosis (DVT) in the leg, demonstrated by fibrinogen scanning. In 10 patients the thrombosis was in the paralysed leg but the degree of paralysis was unrelated to the tendency to develop DVT, which usually occurred about the third day. Leg oedema in 10 patients was unrelated to the DVT. (+info)
Combined liver-spleen-kidney scintigraphy and subsequent subtraction of the kidney scintiphotograph in the evaluation of displaced kidney. (8/1315)The displacement of kidney was studied by using the combined liver-spleen-kidney scintigraphy and the subsequent subtraction of the kidney scintiphotograph to leave the liver-spleen scintiphotograph alone. A suprarenal mass was shown as cold spot between the liver and right kidney on the combined study. When the liver scintiphotograph and kidney scintiphotograph were over-lapped and the differential diagnosis was difficult, the subsequent subtraction of the kidney scintiphotograph was useful in the diagnosis of the enlarged liver.

On the Build-Up Factor from the Multi-Group Neutron Diffusion Equation with Cylindrical Symmetry
We consider the time dependent neutron diffusion equation for one energy group in cylinder coordinates, assuming translational symmetry along the cylinder axis. This problem for a specific energy group is solved analytically applying the Hankel transform in the radial coordinate r. Our special interest rests in the build-up factor for a time dependent linear neutron source aligned with the cylinder axis, which in the limit of zero decay constant reproduces also the static case. The new approach to solve the diffusion equation by integral transform technique is presented and results for several parameter sets and truncation in the solution for the flux and build-up factor are shown and found to be compatible to those of literature [1,2].

SCINTISCANNING SYSTEM FOR STUDY OF REGIONAL DISTRIBUTION OF BLOOD FLOW.
The effect of changes in the direction and magnitude of the gravitational-inertial force environment on the regional distribution of impacted 35-micron diameter microspheres has been measured in the lungs of six anesthetized chimpanzees. These distributions were determined by two computer-controlled scintiscans at 780 sites covering the dorsal and ventral surfaces of the thorax at 1 G subsequent to four injections of differentially isotope-tagged microspheres into the right ventricular outflow tract. Pulse-height analysis at each site allowed separation of count values for the isotopes, and, after correction for collimator distortion, these values were assumed to be proportional to the respective blood flows which were present below each site at the respective time of injections. Computer-generated 3-dimensional and contour map displays of the scintiscan and related physiologic data indicate that pulmonary blood flow tended to redistribute toward the midthoracic region during acceleration exposures

Measurement of Regional Cerebral Blood Flow With 133Xenon and a Multiple-Crystal Scintillation Camera | Stroke
A method was devised to measure gray and white matter cerebral blood flow simultaneously in multiple regions of the brain using 133Xenon and a multiple-crystal scintillation camera. Following magnification cerebral arteriography, 133Xe was injected into the internal carotid artery and the washout of tracer was monitored with a scintillation camera which consists of 294 individually collimated NaI (TI) crystals. These data, obtained from each crystal overlying the brain, were processed by a weighted least-squares nonlinear regression technique. The blood flow rates of the rapid and slow compartments were calculated by the Kety-Schmidt formula along with 95% confidence limits for each measurement.. In four patients, local increases or decreases in regional cerebral flow were correlated with areas of pathology. In one patient with a cerebral arteriovenous malformation, regions of local shunting of tracer were identified. Application of a three-compartment analysis to these curves permitted ...

In nuclear imaging, short-lived radiopharmaceuticals (radioactive drugs that emit gamma rays and that are attracted to the organ of study) are injected into a patients bloodstream. The nuclear camera takes an image of the pharmaceutical as it enters and concentrates in these tissues or organs.. By tracing this blood flow activity, the resulting nuclear medicine image tells physicians about the biological activity of the organ or the vascular system that nourishes it.. Nuclear Medicine has a wide variety of uses, including the diagnosis of cancer, studying gall bladder disease, circulatory problems, detecting thyroid, liver, and kidney malfunction, and other abnormalities in bones, tissues, and organs.. ...
Radiology | Coffee Regional Medical Center
Uses injections of small amounts of radioactive material. The radioactive isotopes tag to the specific organ, tissue, or bone of interest, where they emit gamma rays to a special camera, producing clear images that can pinpoint molecular activity. This helps identify diseases like many types of cancer and cardiac, GI, endocrine, neurology and other disorders. It has the potential to detect disease in its early stages and also offers the potential to see metastases in tissue or bone or to check function of the gall bladder, liver, spleen and other organs. CRMC also uses nuclear medicine image to examine the lymphatic system. Thanks to the ability to image metabolic activity, physicians may see a patients immediate response to drugs or other therapeutic interventions. The Nuclear Medicine departments nuclear medicine cameras include a Phillips Bright View and Phillips Forte imager, a single head Picker, Prism 1500 XP and a dual head Philips, Forte, with half the scan time of traditional ...

Evaluation of potassium-43 scintillation images during early myocardial ischemia in an animal model. | Circulation
To assess the validity of myocardial imaging with potassium-43 (43K) early after the onset of ischemia, the left anterior descending artery was occluded with a baloon tip catheter in 32 intact anesthetized dogs. 99mTechnetium ventriculograms localized the left ventricle. 43K was administered intravenously and serial images were obtained in four views using an Anger camera with a pinhole collimator. The heart was arrested after 60 minutes and removed for imaging and tissue counts to ascertain extracardiac and geometric factors. In normals (group 1) left ventricular images were relatively homogeneous, except for the thin walled apex, both in vivo and in the isolated heart. Equilibration with 43K prior to ischemia (group 2) gave similar images to group 1, associated with a small reduction in tissue count after one hour of ischemia. Group 3 was infused with 43K after initiation of ischemia. Despite a reduction of 43K counts in the ischemic area to less than one-fourth of the nonischemic site (P less ...

The lateral patellar retinaculum defect: anatomical study using ultrasound | ISM
Objective: The purpose of this study was to evaluate whether ultrasound allows precise assessment of a focal defect at the lateral patellar retinaculum (LPR) and to determine its anatomical significance. Materials and methods: This work was initially undertaken in four cadaveric specimens and followed by high-resolution ultrasound study in 48 healthy adult volunteers (96 knees) by two musculoskeletal radiologists. Dimension and location of the LPR defect and its relations to adjacent anatomical structures were analyzed. Results: A focal defect of the LPR through which vessels penetrated was constantly identified by ultrasound in our population. The mean transverse diameter of the defect was 2.4 mm (range, 1-6 mm). The defect was located a mean of 23.7 mm (range, 18-30 mm) proximal to the lateral tibial plateau and 6.6 mm (range, 4-9 mm) lateral to the patellar tendon. Anatomical dissection demonstrated that the LPR defect is related to perforating vessels that originate from the peripatellar ...

WE-E-18A-06: To Remove Or Not to Remove: Comfort Pads From Beneath Neonates for Radiography (Journal Article) | SciTech Connect
Purpose: To obtain an analytical empirical formula for the photon dose source term in forward direction from bremsstrahlung generated from laser-plasma accelerated electron beams in aluminum solid targets, with electron-plasma temperatures in the 10-100 keV energy range, and to calculate transmission factors for iron, aluminum, methacrylate, lead and concrete and air, materials most commonly found in vacuum chamber labs. Methods: Bremsstrahlung fluence is calculated from the convolution of thin-target bremsstrahlung spectrum for monoenergetic electrons and the relativistic Maxwell-Juettner energy distribution for the electron-plasma. Unattenuatted dose in tissue is calculated by integrating the photon spectrum with the mass-energy absorption coefficient. For the attenuated dose, energy dependent absorption coefficient, build-up factors and finite shielding correction factors were also taken into account. For the source term we use a modified formula from Hayashi et al., and we fitted the ...

- Sympathetic innervation imaging can provide insights into the prognosis of patients with HF and, in the future, may evolve into a prognostic tool to help risk stratify patients who will benefit from particular interventions including device therapy. (acc.org)
- Simpson's rule had low correlation to the radionuclide EF (r = 0.45 to 0.51) and could not be used in approximately half of the patients due to poor identification of endocardial borders. (nih.gov)
- However, with experienced sonographers, the LV wall motion score index or visual estimation of the EF had reasonable agreement with the radionuclide EF in most of the patients. (nih.gov)
- Quantification of activity in bone after administrations of 100 kBq/kg of Ra-chloride proved the feasibility of quantitative imaging of patients who have received radionuclide therapy. (lu.se)
- This observation has led to testing radiolabeled annexin V in animal models of acute thrombosis and imaging of atrial thrombi in patients with atrial fibrillation ( 14 , 15 ). (pnas.org)
- Here, a review of the recent developments in PSMA-based diagnostic imaging and therapy in patients with PCa with radiolabeled PSMA ligands is provided. (ru.nl)
- Furthermore, some of these imaging strategies have the potential to be translated to patients, which makes them plausible to be used in the clinics. (iospress.com)
- The focus is on in vivo imaging of animal models and patients. (biomedcentral.com)
- We conclude that the EF estimated from quantitative echocardiographic volume calculations (Simpson's rule) may differ substantially from radionuclide methods of measuring the EF. (nih.gov)
- Due to the incidence of CAD, there is a need for accurate, inexpensive, and non-invasive imaging methods for both diagnosis and monitoring. (tsnmjournals.org)
