shows native T1 maps (top series numbers 1-4) and post gad (bottom series numbers 5-8). One basal and one mid level were selected and the acquisition repeated twice both before and after the administration of gad. Regions of interest (ROI) were drawn in the myocardium and blood. The scan was repeated using the same protocol within 60 days. To mimic routine clinical practice, the staff undertaking the second scan were not aware of the slice position used for acquisition during the first scan. There were no significant differences in heart rate between the two scans.To mimic routine clinical practice, the staff undertaking the second scan were not aware of the slice position used for acquisition during the first scan.
