Comparison between Gated SPECT and Echocardiography in Evaluation of Left Ventricular Ejection Fraction
نویسنده
چکیده
Left ventricular (LV) function and volumes, along with myocardial perfusion, have major diagnostic and prognostic importance inpatients with coronary artery disease [4,11,13,14, 18,20,27]. Myocardial perfusion scintigraphy is a well-established technique for evaluation of myocardial perfusion [16,26,37,38]. Electro cardiographic gating during the acquisition of SPECT perfusion images has become possible to simultaneously assess LV perfusion, function and volumes. Both 99mTc and 201Tl, the most commonly used tracers for perfusion scintigraphy, can be used for gated SPECT purposes [5, 7,8,9,22, 25,28].

Diastolic left ventricular functional indices: Comparison between gated myocardial perfusion SPECT and echocardiography
Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...

Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studie...

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 stre...

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 ...
