Study of 18F-DFA PET Imaging to Evaluate Liver Injury and Liver Failure in Adults

What this Trial Is About

Researchers are investigating the use of 18F-DFA PET imaging to evaluate liver injury, a condition involving rapid liver function decline with symptoms like increased liver enzymes, jaundice, and abdominal discomfort. This observational study aims to assess how accurately this imaging method detects liver damage compared to standard clinical biochemical tests and liver biopsy, which is the current gold standard despite its sampling limitations. The study focuses on adults clinically diagnosed with liver damage or liver failure, exploring the correlation between 18F-DFA uptake in the liver and liver function indicators. Participants diagnosed with liver injury will undergo 18F-DFA PET imaging as part of the study. This radioactive tracer, based on vitamin C structure, is used to visualize liver function non-invasively. The imaging process involves a PET-CT scan lasting about 10 minutes, followed by a one-hour waiting period in the examination room before leaving. The study will compare imaging results with clinical liver function tests or liver biopsy findings to determine the sensitivity and specificity of this method. During the study, participants will have their liver function monitored using PET-CT scans and clinical biochemical markers. The primary outcomes include changes in liver uptake values on PET imaging at 6 months and the relationship between imaging results and standard liver function indicators. Participants will be followed up as needed, with assessments including liver enzyme levels and other blood tests. The total study duration depends on individual follow-up, and safety monitoring will address any issues related to PET imaging procedures.
