چکیده

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 conventional CMR techniques, though it is unknown whether this improves diagnostic performance.

Performance of myocardial perfusion imaging using multi-focus fan beam collimator with resolution recovery reconstruction in a comparison with conventional SPECT

  Objective: IQSPECT is an advanced high-speed SPECT modality for performing myocardial perfusion imaging (MPI), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. The aim of this study was to compare IQSPECT compared with conventional SPECT interms of performance based on standard clinical protocols. In addition, we examined the concordance between convention...

Assessment of ischaemic burden in angiographic three-vessel coronary artery disease with high-resolution myocardial perfusion cardiovascular magnetic resonance imaging

AIMS This study compared the myocardial ischaemic burden (MIB) in patients with angiographic three-vessel coronary artery disease (3VD) using high-resolution and standard-resolution myocardial perfusion cardiovascular magnetic resonance (perfusion CMR) imaging. METHODS AND RESULTS One hundred and five patients undergoing coronary angiography had two separate stress/rest perfusion CMR studies,...

Tracing ischemic memory by metabolic pathways: BMIPP and beyond

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...

Myocardial perfusion scan accuracy in detection of coronary artery disease - Comparison with exercise stress test [Persian]

Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...
