- Abstract: Objective To explore MRI?indings of gouty arthritis?GA) of?nee joint. Methods A retrospective study was conducted on 14 patients with GA of knee joint diagnosed with dual-energy CT, and their MRI findings were analyzed. Results In 14 patients with GA of knee joint, dual-energy CT showed that uric acid crystals were mainly deposited in tendons, ligaments, synovium and articular cartilage, including 6 cases in quadriceps tendon, 4 cases in patellar ligament, 2 cases in anterior and posterior cruciate ligaments, and the remaining 2 cases mainly involved the synovium around the knee joint. MRI showed that the signals of the tophi were similar to those of muscles on T1WI, while the signals on PDWI was diversified, mainly ranging from heterogeneous isointensity to heterogeneous hyperintensity. Conclusion The location and MRI signal characteristics of knee GA patients are specific, and MRI is conducive to display gout crystallization and early manifestations.
