WebJul 8, 2024 · In CMR we typically divide ischemia into transmural or subendocardial (above or below 50% of transmurality) for severity. Above 10% ischemic myocardium has been used to recommend interventional treatment and <5% medical treatment, 5-10% being the grey zone. For CMR 2 transmural segments would definitely be >10%. WebFeb 24, 2014 · Background: Two-dimensional (2D) perfusion cardiovascular magnetic resonance (CMR) remains limited by a lack of complete myocardial coverage.
