Our purpose was to assess the prognosis of a group of patients with normal stress-only gated-SPECT myocardial perfusion imaging. This was retrospective study that includes 790 patients with normal myocardial stressonly perfusion gated SPECT images. Images were considered as normal if a homogeneous ...
Hypothesis: Phase analysis of gated SPECT imaging can quantify left ventricular mechanical dyssynchrony. Methods: A count based method is used to extract regional systolic wall thickening amplitude and phase from gated SPECT images. Five indices describing the phase dispersion of the left ventricular ...
Gated SPECT images were analyzed for LVEF by the radionuclide core laboratory using quantitative gated SPECT (QGS) software.20 Cardiac magnetic resonance imaging was performed by clinical sites that had the required CMR platform and software.17,21 A minimum of 2 data sets of short- and long-...
The purpose of this investigation was to determine the accuracy of the estimation of ejection fractions (EFs) and left ventricular volumes from a commercially available software package (Quantitative Gated SPECT [QGS]) as a function of different true EFs, count level in the acquisitions, severity ...
Relation of left-ventricular dyssynchrony by phase analysis of gated SPECT images and cardiovascular events in patients with implantable cardiac defibrilla... BACKGROUND: Left-ventricular (LV) dyssynchrony could be measured by gated SPECT myocardial perfusion imaging (MPI). This study examined the rel...

Post-stress LVEF, EDV and ESV measured on gated myocardial perfusion SPECT images within 20-40 min after completion of exercise give reproducible information. J Clin Exp Invest 2010; 1(3): 177-181Bekir TaşdemirEbru TekbaşHabib Çil...
Identification of such stress-induced LV dysfunction improves the sensitivity of myocardial perfusion imaging in the detection of coronary artery disease.20,21 However, because resting gated SPECT images are frequently of low count density, particularly in patients undergoing a low-dose rest–high-dose...
Reconstruction of gated SPECT images is intrinsically a four-dimensional problem. Gated SPECT studies are normally reconstructed frame by frame; thus, the ... MV Narayanan,MA King - 《IEEE Transactions on Nuclear Science》 被引量: 89发表: 1999年 [IEEE 3rd IEEE International Conference on Image ...
