Examples of native T1, post-contrast T1 and extracellular volume (ECV) in a normal control (A) and in a patient (B) and the corresponding profiles of longitudinal, circumferential, and radial strains. A Upper panel shows a normal subject with normal global native T1 (975 ms), post-contrast T1 (472 ms), and ECV (26.3%); Bottom panel shows the same normal subject with normal global longitudinal strain (GLS) (− 17.4%), global circumferential strain (GCS) (− 16.9%), and global radial strain (GRS) (28.4%). B Upper panel shows a patient with increased global native T1 (1120 ms), increased ECV (44.0%), and preserved global post-contrast T1 (500 ms). Bottom panel shows the same patient with reduced GLS (− 6.8%), reduced GCS (− 12.7%), and relatively preserved GRS (18.5%)
