Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically.  Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...

BACKGROUND In contrast to 201TlCl, 99mTc-sestamibi shows very slow myocardial clearance after its initial myocardial uptake. In the present study, myocardial washout of 99mTc-sestamibi was calculated in patients with non-ischemic chronic heart failure (CHF) and compared with biventricular parameters obtained from first-pass and ECG-gated myocardial perfusion SPECT data. METHODS AND RESULTS Af...

UNLABELLED Because of the difficulty of predicting the response of patients with idiopathic dilated cardiomyopathy (IDC) to beta-blocker therapy, this study was performed to evaluate whether gated myocardial SPECT (gated SPECT) could be useful for predicting that response. METHODS We performed gated SPECT with (99m)Tc-sestamibi on 38 patients with IDC before treatment with a beta-blocker and ...

The aim of the study was to evaluate the performance of multislice computed tomography (MSCT) for the detection and semiquantitative analysis of healed myocardial infarct in comparison to single-photon emission computed tomography (SPECT). Recently, MSCT was shown to allow detection of myocardial infarct by the presence of hypoenhanced areas. However, direct comparisons to other imaging modalit...

Introduction: The purpose of this study is to assess the integrated role of scintigraphy by Tc99m MIBI in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated SPECT study could be a complementary routine workup for patient with positive parathyroid adenoma on Tc99m MIBI parathyroid scan. Methods: Rest myocardium perfusion gated S...

AIM To determine the clinical utility of the gated myocardial perfusion SPECT to detect silent ischemia in asymptomatic diabetic patients without previous coronary events and to evaluate the prognosis of this population. MATERIAL AND METHODS A retrospective study of 56 asymptomatic diabetics referred for a gated myocardial perfusion SPECT for diagnosis of ischemic disease was performed. The c...

Study on the effects of coronary revascularization and medical treatment on the prognosis of patients with ischemic cardiomyopathy who satisfy myocardial viability criteria on gated single-photon emission computed tomography (SPECT) assessment of myocardial perfusion. In total, 140 consecutive patients with ischemic cardiomyopathy were studied at rest using gated-SPECT and technetium-labeled co...
