Quantitative gated SPECT-derived phase analysis on gated myocardial perfusion SPECT detects left ventricular dyssynchrony and predicts response to cardiac resynchronization therapy.

UNLABELLED The significance of left ventricular (LV) dyssynchrony for the prediction of response to cardiac resynchronization therapy (CRT) has been demonstrated. Parameters reflecting LV dyssynchrony (phase SD, histogram bandwidth) can be derived from gated myocardial perfusion SPECT (GMPS) using phase analysis. The feasibility of LV dyssynchrony assessment with phase analysis on GMPS using Qu...

Impact 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...

Dipyridamole 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...

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...

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 ...
