Assessment of hepatic signal change in free breathing continuous multiphasic dynamic EOB-MRI with compressed sensing and self-gating technique

In the analysis of the hepatic contrast enhancement parameters based on continuous data of the signal changes over time obtained by free-breathing continuous multiphasic dynamic EOB-MR imaging using compressed sensing and self-gating technique, contrast enhancement ratio (CER) in the portal phase and 5min early hepatocyte phase had significant correlation with hepatic contrast enhancement effects in the 20min hepatobiliary phases and showed significant difference between sufficient and insufficient hepatobiliary phases enhancement groups, suggesting that sufficient 20min hepatobiliary phases enhancement may be estimated by the CER in the portal phase and 5min early hepatocyte phase.
