Systolic-Phase Black-Blood Imaging for Fatty Tissue Detection in Arrhythmogenic Right Ventricular Dysplasia
Slavin G, Schmidt E, Holmvang G
Arrhythmogenic right ventricular dysplasia (ARVD), one of the leading causes of sudden death, is a disease where RV muscle is replaced by fatty or fibrotic tissue. It is currently diagnosed with MRI utilizing a variety of imaging sequences to evaluate wall-motion abnormalities, the presence of scar tissue, and the presence of fatty regions in the right ventricular wall. A breath-held, black-blood fast spin echo (FSE) sequence, timed for the systolic cardiac phase, is presented. Data acquisition occurs at the cardiac phase where the RV is thickest, allowing for easier detection of small fat layers.
