It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...

Introduction: The aim of this study was to evaluate the impact of measurement of coronary artery calcification score (CAC) in patients with suspected coronary artery disease (CAD) and a normal myocardial perfusion scan. Methods: In a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of CAD and a normal perfusion scan. In ...

introduction: asymptomatic diabetic patients are at increased risk of cardiovascular complications. myocardial perfusion scan may be effective in risk evaluation in this population. methods: 106 asymptomatic diabetic patients (age: min: 37, max: 82, mean: 57.73±8.88), including 56 females (52.8%) and 50 males (47.2%) were enrolled in the study. myocardial perfusion scintigraphy was performed by...

The isolated perfused rat kidney experiment was introduced in 1959 for studying the regulation of renal blood flow and is recognized as a valuable preparation for studying physiological and biochemical aspects of renal function such as hemodynamics, glomerular filtration rate (GFR) and overall handling of fluids. Dose-response curves are obtained by injection of bolus doses of drugs into the pe...

Abstract Purpose of Review The purpose this review is to provide a summary on the status art simultaneous perfusion-innervation imaging by CZT-SPECT and clarify its potential applications in clinical practice. Recent Findings Introduction CZT cameras represented critical breakthrough nuclear cardiology. Although it has been demonstrated that cardiac innervation may be easily assessed CZT-SPECT,...

introduction: differentiating between ischemic cardiomyopathy (icm) and idiopathic dilated cardiomyopathy (idcm) is important as coronary revascularization can improve prognosis in the ischemic subgroup. due to inherent problems of coronary angiography in patients with depressed ejection fraction (ef) introducing a noninvasive tool to diagnose those who will benefit from angiography seems to be...

background subdiaphragmatic activity can produce subdiaphragmatic-related artifacts, which can degrade the quality of myocardial perfusion imaging (mpi). objectives we examined the impact of drinking milk, water, and lemon juice on different subdiaphragmatic-related artifacts by using 99mtc-sestamibi myocardial single-photon emission computed tomography (spect) in order to determine a feasible ...

Tc-99m-MIBI is an isonrtrile derivative used for evaluation of myocardial perfusion in recent years. In this preliminary report, 7 patients with coronary artery disease are evaluated with Tc-99m-MlBl stress planar and sped studies. Good correlation with coronary angiography is observed in these cases. In view of inherent technical problems present with thallium 201, Tc-99m-MIBi is a good ...

A known case of nephrotic syndrome aged 32 months was admitted to ICU because of loss of consciousness. In physical exam he had tachycardia, tachypnea and hypotension. Lab data showed metabolic alkalosis and hypoxia. In CXR, vascular cut off was seen in right lung and perfusion lung scan showed absence of perfusion in the right lung.Treatment was started with heparin and streptokinase, bu...
