Use of cine gradient echo (GRE) MR in the imaging of cardiac hemochromatosis.

This case report describes the MR appearance of cardiac iron deposition using spin echo and cine gradient echo imaging (GRE) in a young man with secondary hemochromatosis. The ratio of the signal intensity of left ventricular myocardium to skeletal muscle was abnormally low on both spin echo and GRE compared with normal. The abnormally low myocardial signal was most severe on the cine gradient echo sequence. Cine GRE can be used to establish the diagnosis of cardiac iron deposition.
