From: Phenotypes of hypertrophic cardiomyopathy. An illustrative review of MRI findings
T1 mapping in a 67-year-old woman with basal anterior and anteroseptal HCM. a, Short-axis nonenhanced MOLLI (1.5 T) T1 map shows prolonged T1 values in the area of myocardial hypertrophy (arrows). b, T1 map obtained at LGE MR imaging shows abnormal shortening of the T1 values in the hypertrophied segments (arrowheads). The extracellular volume (ECV) for the hypertrophied segments was abnormally elevated (44,6 vs 29% for the lateral wall) (haematocrit, 0.42). Normal ECV values of 25.3 ± 3.5% (1.5 T). c, LGE MR image through the same plane shows midwall enhancement in the hypertrophied segments (arrow)
