Associated factors for a false negative cardiovascular magnetic resonance perfusion study: a CE-MARC substudy
Background Diagnosis of coronary ischemia by perfusion CMR has high sensitivity and specificity when using X-ray coronary angiography as the reference standard. A variety of possible reasons have been given for false negative perfusion CMR studies, such as suboptimal image quality, technical reasons, or the potential discrepancy between angiographic stenosis and detectable myocardial hypoperfus...
متن کاملFactors associated with false‐negative cardiovascular magnetic resonance perfusion studies: A Clinical evaluation of magnetic resonance imaging in coronary artery disease (CE‐MARC) substudy
PURPOSE To examine factors associated with false-negative cardiovascular magnetic resonance (MR) perfusion studies within the large prospective Clinical Evaluation of MR imaging in Coronary artery disease (CE-MARC) study population. Myocardial perfusion MR has excellent diagnostic accuracy to detect coronary heart disease (CHD). However, causes of false-negative MR perfusion studies are not wel...
متن کاملThe role of cardiovascular magnetic resonance in women with suspected CAD: a CE-MARC substudy
Background Coronary artery disease (CAD) is the leading cause of death in women but despite this they are often underrepresented in non-invasive imaging studies. Furthermore, the use of myocardial perfusion imaging in women presents challenges not encountered in men including a low premenopausal prevalence of CAD, more atypical symptoms, a different pattern of disease (more frequent single-vess...
متن کاملCardiovascular magnetic resonance stress perfusion compared to single-photon emission computed tomography (SPECT) in patients with left main stem disease: a CE-MARC substudy
We compared detection rates for cardiovascular magnetic resonance (CMR) perfusion and single photon emission tomography (SPECT) in the subset of patients from the CE-MARC study with significant left main stem (LMS) disease. Detection rates for LMS disease by CMR perfusion were higher than for SPECT, and CMR identified a classical LMS pattern with higher frequency. Visual perfusion defects occur...
متن کاملA comparison of cardiovascular magnetic resonance and single photon emission computed tomography (SPECT) perfusion imaging in left main stem or equivalent coronary artery disease: a CE-MARC substudy
BACKGROUND Assessment of left main stem (LMS) stenosis has prognostic and therapeutic implications. Data on assessment of LMS disease by cardiovascular magnetic resonance (CMR) and single photon emission computed tomography (SPECT) are limited. CE-MARC is the largest prospective comparison of CMR and SPECT against quantitative invasive coronary angiography (QCA) for detection of coronary artery...
