From: Cardiac MRI T1 mapping and extracellular volume application in hypertrophic cardiomyopathy
Case 1: 26-year-old male patient. MRI showed asymmetric LV hypertrophy having anteclockwise pattern, maximum thickness of 17 mm affecting the basal antero-septal segment, LVOT obstruction with a peak velocity of 3 m/s, SAM and LV mass of 245 g (indexed 127 g/m2). I: LGE images at the basal (a), mid-ventricular (b), and apical (c) levels corresponding to the T1 mapping cuts showing no significant enhancement. II: SSFP image in LVOT view showing candle flame artifact of LVOTO (arrow). III: pre-contrast (a–c) and post-contrast (d–f) T1 mapping images at the basal (a, d), mid-ventricular (b, e), and apical (c, f) levels. IV: enhancement pattern and values of native T1 and ECV at the basal, mid-ventricular, and apical segments showing no evidence of myocardial enhancement yet ECV expansion in 9 of the 16 cardiac segments
