Fig. 2From: Fully quantitative pixel-wise analysis of cardiovascular magnetic resonance perfusion improves discrimination of dark rim artifact from perfusion defects associated with epicardial coronary stenosisExamples of a Normal Perfusion Study, a Dark Rim Artifact, and a True Positive Perfusion Defect. The examples illustrate “dark regions” in the subendocardium of CMR perfusion images and appearances on MBF maps. Quantitative measurements of MBF in these regions differentiated the dark rim artifacts from true perfusion defectsBack to article page
