From: T1 mapping is abnormal before decline in EF in patients with Becker and Duchenne muscular dystrophy
Mean T1 times in patients with normal LVEF and dystrophinopathy compared to controls. A subset of patients with Becker muscular dystrophy (BMD) and Duchenne muscular dystrophy (DMD) and normal left ventricular ejection fraction (LVEF) also had a significant decrease in post-contrast T1 when compared to controls. This suggests that myocardial T1 mapping can detect myocardial damage in patients with dystrophinopathy prior to a decline in LVEF.
