The value of the Gated 99mTc-MIBI SPECT in differentiation of fixed myocardial lesions [Persian]
Fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. To increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. In 46 patients (48.8%) fixed perf...
متن کاملClinical usefulness of ECG-gated 18F-FDG PET combined with 99mTC-MIBI gated SPECT for evaluating myocardial viability and function.
OBJECTIVES This study sought to evaluate an imaging approach using gated 99mTc-MIBI (MIBI) SPECT and gated 18F-FDG (FDG) PET for assessment of myocardial viability and cardiac function. METHODS Forty-eight patients (38 men, mean age 68.1 +/- 9.6 years) underwent ECG-gated FDG PET and MIBI SPECT within a week. The baseline diagnoses were coronary artery disease (31), mitral regurgitation (1), ...
متن کاملComparison of the myocardial perfusion and wall motion results by ECG-Gated 99mTc-MIBI SPECT, before and after CABG for evaluation of myocardial viability [Persian]
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...
متن کاملNormal values of left ventricular functional indices in gated 99mTc-MIBI myocardial perfusion SPECT
Introduction: Although left ventricular(LV) function parameters measured by gated myocardial perfusion SPECT (GSPECT) have been validated, experimental data have revealed that the calculated the LV function parameters using GSPECT are affected by patient populations as well as particular acquisition and processing conditions. We tried to determine the normal values ...
متن کاملGated 99mTc-MIBI myocardial perfusion SPECT in patients with right bundle branch block but without evidence of coronary artery disease
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 wit...
