Introduction: We aimed to investigate the effect of right bundle branch block (RBBB) on perfusion and functional parameters in dipyridamole stress/rest Tc99m-MIBI gated myocardial perfusion SPECT (GSPECT) which may be helpful in interpretation of myocardial perfusion imaging. Methods: We studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients wit...

introduction: percutaneous transluminal coronary angioplasty (ptca) is an effective method for revascularizing of stenotic coronary vessels. lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. introduction of a noninvasive method with high predictive value ...

False-positive findings with myocardial perfusion imaging (MPI) have frequently been identified in the presence of left bundle branch block (LBBB) and tend to lower the accuracy of MPI in individuals with normal coronary angiographs. Pharmacologic stress is recognized as the preferred method for MPI in patients with LBBB. In contrast, very few studies have evaluated the effect of right bundle b...

The aim of this study was to assess whether there is an association between changes in the heart rate and blood pressure after dipyridamole stress and abnormal scan findings detected with gated technetium-99m methoxy isobutylisonitrile (99mTc-MIBI) myocardial perfusion imaging (MPI). A total of 200 consecutive patients with known or suspected coronary artery disease underwent MPI using a 2 days...

A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...

objective: although coronary artery disease (cad) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. myocardial perfusion imaging (mpi) is reported to show ischemia in a significant number of asymptomatic diabetic patients. we studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. meth...

discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

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...
