N2 - Coronary artery disease and its related cardiac disorders represent the most common cause of death in the USA and Western world. Despite advancements in treatment and accompanying improvements in outcome with current diagnostic and therapeutic modalities, it is the correct assignment of these diagnostic techniques and treatment options which are crucial. From a diagnostic standpoint, SPECT myocardial perfusion imaging (MPI) using traditional radiotracers like thallium-201 chloride, Tc-99m sestamibi or Tc-99m tetrofosmin is the most utilized imaging technique. However, PET MPI using N-13 ammonia, rubidium-82 chloride or O-15 water is increasing in availability and usage as a result of the growing number of medical centers with ...

N2 - Background and objective: The absolute quantification of dynamic myocardial perfusion (MP) PET imaging is challenged by the limited spatial resolution of individual frame images due to division of the data into shorter frames. This study aims to develop a method for restoration and enhancement of dynamic PET images. Methods: We propose that the image restoration model should be based on multiple constraints rather than a single constraint, given the fact that the image characteristic is hardly described by a single constraint alone. At the same time, it may be possible, but not optimal, to regularize the image with multiple constraints simultaneously. Fortunately, MP PET images can be decomposed into a superposition of ...
The heart failure (HF) epidemic continues to rise with coronary artery disease (CAD) as one of its main causes. Novel concepts for risk stratification to guide the referring cardiologist towards revascularization procedures are of significant value. Myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) agents has demonstrated high accuracy for the detection of clinically relevant stenoses. With positron emission tomography (PET) becoming more widely available, mainly due to its diagnostic performance in oncology, perfusion imaging with that modality is more practical than in the past and overcomes existing limitations of SPECT MPI. Advantages of PET include more reliable quantification of absolute myocardial blood flow, the routine use of computed tomography for attenuation correction, a higher spatiotemporal resolution and a higher count sensitivity. Current PET radiotracers such as rubidium-82 (half-life, 76 sec), oxygen-15 water (2 min) or nitrogen-13 ammonia (10

Methods A total of 22 patients with chronic ischemic cardiomyopathy (ICM) and 11 control subjects with normal CT coronary angiogram were studied. Rest 82Rb PET/CT studies were acquired in list mode and resampled to static, gated, and dynamic images. Using a 17-segment model, 82Rb washout was determined by monoexponential fitting of myocardial time-activity curves. In ICM patients, ...
Rubidium-82 (82Rb) is a radioactive isotope of rubidium. 82Rb is widely used in myocardial perfusion imaging. This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging. 82Rb is used in the pharmaceutical industry and is marketed under the trade name CardioGen-82. In 1953 it was discovered that Rubidium carried a biological activity that was comparable to potassium. In 1959, preclinical trials showed in dogs that myocardial uptake of this radionuclide was directly proportional to myocardial blood flow. In 1979, Yano et al. compared several ion-exchange columns to be used in an automated 82Sr/82Rb generator for clinical testing. Around 1980, pre-clinical trials began using 82Rb in PET. In 1982, Selwyn et al. examined the relation between myocardial perfusion and rubidium-82 uptake during acute ischemia in six dogs after coronary stenosis and in five volunteers and five patients with ...

This article presents the exciting advances made and ongoing in the area of pharmacologic cardiac stress testing. In particular, new A(2A)-specific receptor agonists work like adenosine but promise the delivery of uncomplicated vasodilator stress testing or the diagnosis and prognosis of coronary disease. These agents, although not perfect, do likely present a level of protection against the complications of bronchospasm and heart block. Phase III studies have shown that these agents promise a reduced symptom intensity and greater patient tolerance. One of these agents, regadenoson, is now Food and Drug Administration approved and will be delivered as the same single-dose bolus in all patients, regardless of weight, greatly simplifying the method and increasing its acceptability. Most widely applied with myocardial perfusion SPECT, these agents will find application with PET myocardial perfusion studies and likely MRI studies. Because of their effect on coronary supply rather than demand, they ...
Position Emission Tomography (PET) - Myocardial Perfusion Scan. PET stands for Positron Emission Tomography and is an imaging technique which uses small amount of a radioactive tracer to help in the diagnosis of heart disease.. The commonest tracer used in Rubidium-82(Rb-82 or 82Rb). 82Rb is a potassium analogue that is a generator product with a physical half-life of 76 seconds. Owing to the distinct advantage of not requiring an on-site cyclotron, 82Rb is the most widely used radioactive tracer for assessment of myocardial perfusion with PET.. The 82Rb tracer is introduced into the body by intravenous (I/V) injection directly from a small portable generator and a PET Scanner is used to produce an image showing the distribution of the tracer in the heart muscles.. Following the intravenous administration, 82Rb is carried in the blood stream and in the blood vessels supplying the heart muscles. 82Rb is then rapidly taken up by the heart muscles. 82Rb activity is noted in the heart within the ...
ad_1]. Rubidium rare trace element that is not very abundant in the human body. But despite the rarity and low in the body, it has some very important functions to perform health. Without further ado, lets get straight to the use of rubidium. four medical purposes and health benefits of Rubidium 1. It helps in the prevention of diabetes The mineral Rb plays a vital role in the synthesis of enzymes . One such enzyme, which helps to create rubidium is essential for proper absorption of glucose in the body. Without rubidium to help the action of the enzyme, glucose molecules would not be able to get absorbed efficiently, so that diabetic problems. Therefore, one of the most important uses of rubidium to reduce the chances of diabetes. 2. Maintain the hormonal balance: Studies have shown that the production of the rubidium enhance many different hormones and enzymes. The working range of the pituitary gland, and the salivary glands and lacrimal glands, encouraged by the presence of rubidium. . ...
In order to determine what gradients in local rates of myocardial blood flow are present in the resting hemodynamic state, the regional rates of myocardial clearance of 86Rb were measured in dogs tranquilized with chlorpromazine. The clearance rate in the left ventricle corresponded to an average coronary flow of 11.7 ml/g per 10 min. Estimated right ventricular flow was 7.1 ml/g per 10 min and left atrial flow 7.9 ml/g per 10 min. High rates of 86Rb uptake were noted in the atrial appendages and papillary muscles. Uptake in serially sectioned cores from both ventricles was consistently highest near the endocardial surface and decreased toward the epicardium. Selective injections of 86Rb into the aorta or vena cava demonstrated that isotope penetrated the myocardium from the cavities of both ventricles. In the right ventricle, high subendocardial 86Rb clearance was not found unless the isotope had been present within its cavity. In the left ventricle, in contrast, more 86Rb was taken up by the ...

Arterial Spin labeling (ASL) is a fully non-invasive MRI method capable to quantify cerebral perfusion. However, gray (GM) and white matter (WM) ASL perfusions are difficult to assess separately due to limited spatial resolution increasing the partial volume effects (PVE). In the present study, ASL PVE correction was implemented based on a regression algorithm in 22 healthy young men. PVE corrected perfusion of GM and WM were compared to previous studies. PVE-corrected GM perfusion was in agreement with literature values. In general, WM perfusion was higher despite the use of PVE correction.. ...

Tracking coronary artery disease (CAD) via myocardial perfusion imaging (MPI) may have value in guiding therapeutic management for minimizing coronary event risk. Few studies have evaluated the effects of changes in myocardial perfusion as measured by positron emission tomography (PET MPI) on clinical outcomes. Accordingly, this study identified 552 patients who underwent serial rubidium-82 PET MPI for evaluation of suspected or known CAD. The extent of left ventricular (LV) stress perfusion defects was measured at both scans Objectivesly by automated software as the percentage of the LV mass with ,60% relative perfusion. All patients received aggressive medical therapy and 12% underwent interim revascularization. Mortality information was obtained through the National Death Index with mean follow-up of 2.5 years. Cox models were developed to estimate the effects of changes in stress perfusion defect size (change between serial scans in % of LV with stress perfusion defects) on all-cause and ...
Exposure to particulate air pollution is associated with increases in cardiovascular mortality and morbidity. The pathophysiological mechanisms underlying this observation are emerging, and exposure to particulate air pollution has been shown to result in increases in blood pressure and arterial tone, impaired vascular function and an increased tendency for blood to clot as well as an increase in atherosclerotic plaque burden. Recent evidence from panel studies and controlled exposure studies have suggested an increase in myocardial ischaemia (a reduction in blood flow to the heart) following exposure. In this study we aim to investigate directly myocardial (heart) blood flow following exposure to diesel exhaust (as a model of urban air pollution) using CT/PET myocardial perfusion imaging in male patients with stable coronary disease and healthy male controls. We hypothesize that following exposure to dilute diesel exhaust:. ...

Three 35-amino acid peptide K+ channel toxins (pandinotoxins) were purified from the venom of the scorpion Pandinus imperaton the toxins are designated pandinotoxin (PiTX)-K alpha, PiTX-K beta, and PiTX-K gamma. In an 86Rb tracer flux assay on rat brain synaptosomes, all three toxins selectively blocked the component of the K(+)-stimulated 86Rb efflux that corresponds to a voltage-gated, rapidly inactivating (A-type) K+ current (IC50 = 6, 42, and 100 nM, respectively). These toxins blocked neither the noninactivating component of the K(+)-stimulated 86Rb efflux (corresponding to a delayed rectifier) nor the Ca(2+)-dependent component of the 86Rb efflux (i.e., a Ca(2+)-activated K+ current) in these terminals. PiTX-K alpha, which was expressed by recombinant methods, also blocked the Kv1.2 channel expressed in fibroblasts (IC50 = 32 pM). PiTX-K alpha and PiTX-K beta have identical amino acid sequences except for the seventh amino acid: a proline in PiTX-K alpha, and a glutamic acid in PiTX-K ...
