The Utility of Gadoxetic acid-Enhanced MRI in Quantitative Assessment of Transplanted Liver: Functional T1 Mapping

Motivation: Gadoxetic acid-enhanced MRI is a promising tool for assessing liver function, especially in the context of liver transplants. Goal(s): This study aims to examine the relationship between functional T1 mapping from gadoxetic acid-enhanced MRI and transplanted liver function. Approach: Liver transplant recipients underwent liver MRI, including T1 mapping and gadoxetic acid-enhanced MRI, to evaluate the relationship between MRI parameters and MELD. Results: Liver transplant recipients at low or moderate risk had significantly higher ΔT1% values compared to high-risk recipients. Impact: Gadoxetic acid-enhanced MRI offers dynamic and hepatocyte-specific imaging, making it a comprehensive "one-stop" method for post-transplant complication and liver injury evaluation.
