UNLABELLED The purpose of this study was to investigate the significance of abnormal 67Ga-citrate skull uptake in AIDS patients with mycobacterioses. METHODS Gallium-67 scans of 39 HIV-positive patients who have been diagnosed with mycobacterioses were analyzed; the scans of 15 consecutive HIV-positive patients without mycobacterioses were also reviewed(More)
UNLABELLED This work aimed to assess the significance of abnormal gastroduodenal uptake in the 67Ga scintigraphy of HIV patients who have been studied for fever of unknown origin. The examinations of 12 patients who had had a normal panedoscopy when the 67Ga scan was done, were selected. One out of 7 patients without gastroduodenal 67Ga uptake was diagnosed(More)
AIM To report our data concerning the changes in post-stress and at-rest left ventricular ejection fraction and ventricular volumes in patients with thallium gated SPECT. METHODS Post-stress and at-rest thallium gated SPECT was performed in 629 consecutive patients; left ventricular ejection fraction (LVEF), left ventricular volumes and quantitative(More)
BACKGROUND Successful revascularization of ischemic asynergic myocardium should be followed by improvement in contractile function. However, a clear improvement is not always observed. Assessment of contractile reserve may allow a better evaluation of procedural results. METHODS AND RESULTS To assess the changes in global and regional left ventricular(More)
INTRODUCTION This study has aimed to establish quantitative normality parameters in the thallium-201 GATED SPECT and to assess the changes related to age, gender, risk factors and stress testing. METHODS A total of 427 patients with low pre-test likelihood of coronary artery disease were selected (45.5% men). The examinations were performed, by obtaining(More)
The meaning of a stress-induced ST-segment elevation (delta ST) after acute myocardial infarction is still controversial. Some studies show it is related to asynergy, and other studies show it is related to ischemia. However, no study has compared the delta ST with both stress-induced ischemia and stress-induced asynergy in the same group of patients. With(More)
The purpose of this study was to determine the prognostic value of a normal 201Tl scan in patients with a positive treadmill exercise stress test. We analyzed retrospectively 85 consecutive patients with a positive treadmill exercise test and normal Tl201 scan who were studied for the diagnosis of coronary artery disease from January 1996 to December 2000.(More)
OBJECTIVE The aim of this study was to compare a recently described method to evaluate endothelial function; the hyperemic reactivity scintigraphy (HRS) with the ultrasonographic flow-mediated dilatation (FMD) in brachial artery and its relationship with myocardial SPECT. METHODS 42 consecutive patients that underwent myocardial scintigraphy were(More)
INTRODUCTION The aim of this work was to describe the variables associated to silent ischemia in patients with reversible perfusion defects in poststress myocardial perfusion scintigraphy. METHODS Tl-201 myocardial perfusion SPECT of 522 patients showing total or partially reversible perfusion defects after exercise testing were quantitatively analyzed(More)
