Simultaneously multi-parameter quantification is recently a hot research topic for MRI. A series of techniques are available, such as MR fingerprinting, MAGIC and STAGE. This study proposed a rapid and high-quality T1/T2* quantification method, called TXI. The results showed that it can generate high SNR T1 and R2* maps with less motion artifacts, which is superior to the conventional T1 and R2* mapping method. The T1 map is significantly improved with higher measurement consistency among different liver regions than conventional method.
