Exploring the Application Value of New Magnetic Resonance Imaging Technologies in Non-invasive Quantitative Assessment of Graft Function After Liver Transplantation

"\### Intervention Description~The intervention in this study is the use of advanced MRI techniques for assessing liver transplant graft function. It includes:~* \*\*Diffusion Weighted Imaging (DWI):\*\* To evaluate tissue integrity and detect early graft dysfunction.~* \*\*Dynamic Contrast-Enhanced MRI (DCE-MRI):\*\* To assess vascular complications and blood flow in the graft.~* \*\*Blood Oxygenation Level-Dependent (BOLD) MRI:\*\* To monitor oxygenation levels, indicative of graft health.~These MRI methods provide a non-invasive, comprehensive assessment of liver graft function, distinguishing this intervention from traditional invasive methods like biopsy."
