A Prospective Study of ¹⁸F-DFA PET Imaging for the Assessment of Liver Injury

Inclusion Criteria1

• \) Aged between 18 and 80 years old; 2) Clinically diagnosed with liver damage (combined with medical history and laboratory tests, manifested as changes in liver enzymes, abnormal bilirubin metabolism, dysfunction of substance synthesis, and decreased biodegradation function, including indicators such as ALT, AST, ALP, GGT, albumin (Alb), TBil, and DBil); 3) Clinically diagnosed with liver failure (liver failure is a severe liver damage caused by multiple factors, resulting in severe dysfunction or decompensation of its synthesis, detoxification, excretion, and biotransformation functions, and a group of clinical syndromes with coagulation dysfunction, jaundice, hepatic encephalopathy, ascites, etc. as the main manifestations. Key points for the diagnosis of liver failure (a) Extreme fatigue, and severe gastrointestinal symptoms such as anorexia, vomiting, and abdominal distension; (b) Progressive deepening of jaundice (serum TBil ≥171μmol/L or daily increase ≥17.1μmol/L); (c) Bleeding tendency, plasma prothrombin activity (PTA≤40% or international normalized ratio (INR ≥ 1.5; (d) hepatic encephalopathy (grade II or above) or other complications.); 4) informed consent and able to accept follow-up, can understand and comply with the requirements of the study
