Magnetic resonance elastography (MRE) has been used for tumor detection and liver fibrosis evaluation. The existence of intratumoral fat suggests a lower risk of microvascular invasion of combined hepatocellular-cholangiocarcinoma. The combination of MRE and fat quantification can provide sufficient sensitivity to detect substantial macrovesicular hepatic steatosis or fibrosis. In clinical practice, MRE and fat quantification are scanned separately. However, this may cause slice mis-registration between MRE and fat quantification, and increase scan time. In this study, the feasibility of simultaneous acquisition for MRE and fat quantification was demonstrated. This technique can have several potential clinical applications without increasing scan time.
