Abstract:

Gout is a common metabolic rheumatism. The main cause is the increase of blood uric acid caused by the disorder of purine metabolism in the body. Long-term persistent hyperuricemia will lead to the precipitation of monosodium urate (monosodium urate, MSU) crystals, which will form and deposit in the internal and external tissues of the joints. Due to the action of inflammatory factors, eventually gouty arthritis. Gout is a widespread disease worldwide, and the prevalence of gout in my country is increasing year by year. Gout is a chronic disease that is often characterized by extreme pain in its acute phase and, in some cases, invades the bone, leading to bone erosion and destruction. Complications of chronic gout include severe bone and joint damage, necrotizing swelling of soft tissue, and bone infection. In severe cases, it can even cause tendon rupture and loss of joint function. Gout is an important disease that seriously endangers the health of the Chinese people. Early diagnosis and intervention of gout are very important. Imaging is not only helpful in diagnosing gout, but can also be used as a monitoring method to evaluate the disease and the effect of uric acid-lowering therapy. Dual-energy CT technology is the most promising technology for non-invasive diagnosis and disease monitoring, and MRI texture analysis technology can also assist in the differential diagnosis of gouty arthritis. This review discusses the role of various imaging tests in gout, focusing on the role of imaging features in gout diagnosis and disease monitoring.
