The classification of synovial reactions caused by adverse local tissue reactions or prosthetic joint infections in total hip arthroplasty patients has remained a challenge due to the in-plane and through-plane distortions caused by metallic components. MAVRIC-based diffusion weighted imaging (DWI) is an innovative MRI technique sensitive to microstructural fluid changes and utilizes apparent diffusion coefficient values for the differentiation of diseased and non-diseased tissues. This study evaluated the effectiveness of MAVRIC-based DWI and T2 mapping in differentiating between types of synovial reactions. Our DWI ADC biomarker showed promise in differentiating between normal and abnormal synovial reaction subtypes within THA patients.
