Performance of free-breathing LGE in non-ischemic cardiomyopathies in two different patients. 1. Twenty-year-old female with hypertrophic cardiomyopathy and patchy LGE in SAx views (a, b, c). Whereas in breath-hold LGE (a), hyperenhanced lesions at mid-anterior and mid-anterolateral segments (arrowheads) seem to be confluent, they can be distinguished as two separate lesions in reformatted free-breathing LGE (b: source images with 0.7 mm slice thickness, c: identical (10 mm) slice thickness as breath-hold LGE) despite suboptimal TI, which leads to a grey myocardium. Further, free-breathing LGE provides improved depiction of a subendocardial lesion at mid-inferior segment (arrows). 2. Fifty-year-old male with sarcoidosis and diffuse hyperenhancement of the anterior wall (arrowheads) in SAx views (d, e, f), pronounced at mid-myocardial localization. In its reformatted source images (e, 0.7 mm slice thickness), free-breathing LGE clearly depicts additional adjacent hyperenhanced lesions (arrow) of the mid-anteroseptal segment at mid-myocardial localization, which are indicated in free-breathing LGE with 10 mm slice thickness (f), but not visible in breath-hold LGE (d)
