Official title:
Study on the Quantitative Assessment of the Risk of Hepatocellular Carcinoma in Patients With Chronic Liver Disease Using Multi-parameter Magnetic Resonance Imaging
Quantitative MRI scanning parameters such as T1 mapping, T2 mapping, T1ρ, and elastography are used, combined with clinical and laboratory indicators, to predict the risk of liver cancer in patients with cirrhosis.
Retrospectively and prospectively collect T1 mapping, T2 mapping, T2* mapping, T1ρ, elastography and other multi-parameter MRI sequence images and clinical and laboratory examination data from patients with liver cirrhosis, and conduct 5-year clinical follow-up and monitoring of all enrolled patients. Whether patients develop hepatocellular carcinoma, patients are divided into liver cancer occurrence group and non-hepatocellular carcinoma group according to clinical follow-up results. Cox proportional hazard analysis is used to compare the differences in clinical characteristics, laboratory tests, imaging characteristics, quantitative MRI parameters and other variables between the two groups of patients. , and calculate the hazard ratio for each variable; assign a score to each covariate based on the proportion of the hazard ratio in the multivariable model, and develop a nomogram to predict HCC risk by the total score. ;
