OBJECTIVE Exercise tolerance in patients with diabetes is frequently impaired due to noncardiac disease such as claudication and polyneuropathy. This study assesses the prognostic value of dobutamine stress myocardial perfusion imaging in patients with diabetes. RESEARCH DESIGN AND METHODS A total of 207 consecutive diabetic patients who were unable to undergo exercise stress testing underwen...

Background: Behçet's disease (BD) is a multi-system vasculitis that can have a wide range of effects on the cardiovascular system. Objective: To determine the existence of myocardial perfusion defects caused by coronary microvascular dysfunction in asymptomatic BD patients with and with out metabolic syndrome and to evaluate coronary arterial distribution and left ventricular systolic function ...

Background First pass myocardial perfusion imaging by CMR may permit the detection of myocardial ischaemia with greater accuracy than single photon emission computed tomography (SPECT). Technical developments have led to improvements in myocardial perfusion CMR, particularly through accelerated data acquisition methods. These permit the acquisition of data at higher spatial resolution than conv...

conclusions the prevalence of undiagnosed ihd in the hd patients was considerable. we, therefore, suggest that ihd be assessed in hd patients, especially those at high risk due to positive family history of cad, hypertension, left ventricular hypertrophy, diabetes mellitus, kt/v < 1.2, low ferritin levels, and high levels of intact parathyroid hormone. results sixty-nine hd patients were studie...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

BACKGROUND Contrast-enhanced steady state free precession (CE-SSFP) and T2-weighted short tau inversion recovery (T2-STIR) have been clinically validated to estimate myocardium at risk (MaR) by cardiovascular magnetic resonance while using myocardial perfusion single-photon emission computed tomography as reference standard. Myocardial perfusion single-photon emission computed tomography has be...

UNLABELLED Cardiac PET/CT is optimized by cine CT with dedicated shift software for manual correction of attenuation-emission misregistration. Separate rest and stress CT scans incur greater radiation dose to patients than does standard helical PET/CT or "pure" PET using rotating rod attenuation sources. To reduce radiation dose, we tested quantitative accuracy of using a single poststress cine...

H. Pedersen, S. Ringgaard, W. Y. Kim The MR Research Centre, Skejby Hospital, Aarhus University Hospital, Aarhus N, Denmark INTRODUCTION Quantitative analysis of myocardial perfusion using free-breathing first-pass perfusion MRI is degraded by respiratory induced motion of the heart. Conventional strategies to correct this motion include the manual alignment of each image to fit a reference ima...
