introduction: we aimed to assess whether the vasodilator effect of oral dipyridamole on the left ventricular systolic function in patients with suspected cad is different from that of intravenous (iv) dipyridamole using tc-99m mibi myocardial perfusion gated spect. methods: eighty-nine patients (17 m / 72 w; 61 ± 10 years) were enrolled in this study. the patients underwent a dipyridamole stres...
introduction: motion of the patient during myocardial perfusion spect could potentially results in false perfusion defects. the effect of different reconstruction methods on these artifacts is not studied. clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. this study...
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...
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 b...
SUMMARY Dipyridamolc-Thallium imaging is a relatively safe and accurate method to evaluate myocardial perfusion in patients who arc unable to exercise to a maximal exertion (5,6,8,9). A 51year-old woman was admitted to Taleghani hospital with clinical symptoms and signs of coronary artery disease. Intravenous dipyridamote-Thallium scan was performed in this case. In multiple views obtained f...
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...
OBJECTIVE To determine whether the size of a perfusion defect seen at myocardial perfusion MR imaging represents the extent of irreversibly damaged myocardium in acute reperfused myocardial infarction. MATERIALS AND METHODS In nine cats, reperfused myocardial infarction was induced by occlusion of the left anterior descending coronary artery for 90 minutes and subsequent reperfusion for 90 mi...
