As a non-invasive imaging technique for detecting and staging liver fibrosis, MR Elastography (MRE) is highly sensitive and specific. Conventional 2D liver GREMRE is very effective, and only takes about 1-2 minutes with multiple breath-holds (11-16 seconds, each). However, shorter acquisition times and fewer breath-holds are always desired for these examinations, especially when patients have difficulty holding their breath. In this study, we developed an 11-second hepatic MRE protocol based on SE-EPIMRE sequence, which was performed in a single breath-hold comfortably; the repeatability of repeated MRE scans was also assessed.
