Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...

Introduction: We aimed to investigate of effect of left bundle branch block (LBBB) on perfusion and functional parameters in dipyridamole Tc99m-MIBI gated myocardial perfusion SPECT which may be helpful in interpretation of myocardial perfusion imaging. Methods: We studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with LBBB and  35 subject...

Evaluating the Effect of Injected Dose 99mTc- MIBI on Quantitative Parameters Myocardial Perfusion Imaging

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...

introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

introduction: the relationship between depression and coronary artery disease is well established; however assessment of this relationship using functional and semi-quantitative imaging (myocardial perfusion scintigraphy) was lacking. the aim of this study was to assess the relationship between the severity of depression and the severity of myocardial perfusion abnormality. methods: patients we...

A cohort of 1,702 patients was referred for exercise Tcsestamibi single-photon emission computed tomography (SPECT) from January 1, 1991, to January 1, 1993, for whom follow-up could be obtained. Patients were followed for 20 6 5 months. Of the 1,131 who had normal or equivocal scan results, 1 cardiac death and 1 myocardial infarction occurred (0.2% event rate), and 17 cardiac deaths and 26 non...
