High-resolution quantitative spiral perfusion for microvascular coronary dysfunction detection
Background Quantitative first-pass CMR can assess the severity of microvascular coronary dysfunction(MCD) in subjects with signs and symptoms of ischemia but without obstructive coronary artery disease(CAD). In patients with MCD, abnormalities of myocardial perfusion reserve (MPR) occur globally but may also vary in their transmural extent. Thus, high spatial resolution quantitative CMR perfusi...
متن کاملComparison of fully quantitative and semi-quantitative measure of women's myocardial perfusion reserve for detection of microvascular coronary dysfunction
Background Myocardial perfusion reserve (MPR) acquired using firstpass cardiac MRI is a measure of the severity of microvascular coronary dysfunction (MCD) in subjects with signs and symptoms of ischemia but no obstructive coronary artery disease (CAD) [Shufelt 2011]. Semiquantitative measures (upslopes) have been used to analyze MPR data in the previous work [Shufelt 2011]. In this work, we pr...
متن کاملPharmacotherapy for coronary microvascular dysfunction.
Coronary microvascular dysfunction (CMD) has been increasingly recognized as an important cardiac condition that can cause signs and symptoms of myocardial ischaemia in various clinical settings. The dysfunction is located on the level of the coronary microcirculation with a vessel diameter of <500 µm and can be characterized by structural as well as functional vascular alterations. The underly...
متن کاملHigh spatial resolution myocardial perfusion cardiac magnetic resonance for the detection of coronary artery disease
AIMS To evaluate the feasibility and diagnostic performance of high spatial resolution myocardial perfusion cardiac magnetic resonance (perfusion-CMR). METHODS AND RESULTS Fifty-four patients underwent adenosine stress perfusion-CMR. An in-plane spatial resolution of 1.4 × 1.4 mm(2) was achieved by using 5× k-space and time sensitivity encoding (k-t SENSE). Perfusion was visually graded for 1...
متن کاملABCD1 dysfunction alters white matter microvascular perfusion
Cerebral X-linked adrenoleukodystrophy is a devastating neurodegenerative disorder caused by mutations in the ABCD1 gene, which lead to a rapidly progressive cerebral inflammatory demyelination in up to 60% of affected males. Selective brain endothelial dysfunction and increased permeability of the blood-brain barrier suggest that white matter microvascular dysfunction contributes to the conver...
