Synopsis

Keywords: Machine Learning/Artificial Intelligence, LiverMR multiparametric quantitative techniques have an important role in liver-related diseases.We achieved simultaneous proton density fat fraction(PDFF), R2*and R1 quantification of different liver diseases using a simultaneous multi-relaxation-time Imaging(TXI) technique.We observed differences of PDFF,R2* and R1 mapping between healthy volunteers and patients with cirrhosis,HCC,metastatic carcinoma of liver,and liver transplantation.Rapid scanning increases usage of this method in the clinic.These quantitative values can be biomarkers for assessing liver function and liver tissue characterization.
