Chronic liver disease
Conditions
Interventions
Gold Standard:Enhanced CT images formed by real scanning
Determination of chronic liver disease types
Malignant diseases such as hepatocellular carcinoma and intrahepatic cholangiocarcinoma have been pathologically confirmed
A benign lesion must meet at least one of the following conditions: (1) confirmed diagnosis by three radiologists
(2) confirmed through follow-up of at least six months using two different imaging methods.
Index test:The first is the enhanced CT image generated based on plain scan images
Secondly, based on the generated enhanced CT images, radiologists make diagnoses of chronic liver diseases
