Myocardial blood flow in patients with significant coronary artery disease. Examples of concordance between different surface coil intensity correction techniques. Patient 1; 90% proximal right coronary artery (RCA) stenosis. A perfusion defect is evident in the inferior wall on the pixel-wise myocardial blood flow (MBF) maps generated using all surface coil intensity correction (SCIC) techniques. Patient 2; 90% proximal left anterior descending coronary artery (LAD) stenosis. A perfusion defect is evident in the anteroseptum and anterior wall on the pixel-wise MBF maps generated using all SCIC techniques.
