Dual-isotope myocardial SPECT in a female patient with idiopathic myocarditis showed completely inverse images in Tl-201 and I-123 MIBG SPECT. In the dual-isotope SPECT performed 13 days after her admission, Tl-201 SPECT images showed reduced accumulation in the apex and normal accumulation in the other regions, whereas the corresponding I-123 MIBG SPECT images showed normal findings in the ape...

Although single photon emission computed tomography (SPECT) is preferable for myocardial perfusion scintigraphy, in a minimal number of circumstances, planar imagingmay be useful ormay be the onlymodality available. Purpose. To evaluate regional myocardial perfusion and function. Planar imaging is an acceptable method for myocardial perfusion imaging. The anatomy of the heart is sufficiently si...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

BACKGROUND Myocardial perfusion radionuclide imaging (MPRI) is a noninvasive method extremely useful for evaluating ischemia in patients with coronary disease. However, the idea that this method would not be effective for patients with multivessel coronary disease is still entertained. OBJECTIVE Assess the value of MPRI with gated-SPECT for tracing pharmacological stress-induced ischemia in p...

objective(s): radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. a prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. methods: to minimize potential confounding fact...

INTRODUCTION Gated SPECT myocardial perfusion imaging (MPI) has been used to quantify mechanical dyssynchrony. Mechanical dyssynchrony appears to be related to response to cardiac resynchronization therapy. OBJECTIVE To evaluate the presence and predictors of mechanical dyssynchrony in patients with impaired left ventricular function (LVEF) ≤50%. METHODS The study included 143 consecutive p...

objective(s): a novel iq-specttm method has become widely used in clinical studies. the present study compares the quality of myocardial perfusion images (mpi) acquired using the iq-specttm (iq-mode),conventional (180° apart: c-mode) and l-mode (90° apart: l-mode) systems. we assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. materials and me...

Myocardial flow reserve (MFR) is not routinely assessed in myocardial perfusion imaging (MPI) studies but has been hypothesized to affect test accuracy when assessing disease severity by coronary vessel lumenography. Magnetic resonance imaging (MRI) is an emerging diagnostic technique that can both perform MPI and assess MFR. We studied women (n = 184) enrolled in the Women's Ischemia Syndrome ...

Coronary heart disease (CAD) is the leading cause of death specially among elderly. Coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. Myocardial perfusion scan is a noninvasive and sensitive method for evaluation of CAD and is suggested by many investigators in recent years. In this study, 64 patients wh...

introduction: left ventricular ejection fraction (lvef) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. lvef is not improved in all patients after coronary artery bypass grafting (cabg). this study aimed to assess the possibility of prediction of lvef changes after cabg using myocardial perfusion gated signle photon emission compu...
