Normal 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 کاملDiastolic 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...
متن کاملechocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction
background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction is associated with lvh and inappropriate lvm. methods: one hundred and twenty five uncomplicated hypertensi...
متن کاملDipyridamole stress and rest gated 99mTc-sestamibi myocardial perfusion SPECT: left ventricular function indices and myocardial perfusion findings
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...
متن کاملImpact of Phase Analysis of Gated SPECT to Assessment of Left Ventricular Mechanical Dyssynchrony in Diabetic Patients with Normal MPI
Objective: Diabetes mellitus is an important cause of heart failure deployment of left ventricular mechanical dyssynchrony. Nuclear cardiology phase analysis is an accurate, repeatable and reproducible modality for measurement LV dyssynchrony .The aim of study was assessment of phase analysis parameter including Standard deviation (SD) and band width (BW) in diabetic patient with normal MPI com...
