Objective: Of the most commonly involved joint in gouty arthritis is the first metatarsophalangeal joint, followed by other foot joints, ankle joints, hand and wrist joints and knee joint, etc. Gouty arthritis includes soft tissue swelling, monosodium urate deposition (tophus), bone destruction, and joint effusion. We intended to explore the joint characteristics of gouty arthritis via computed tomography (CT) scanning.

Methods: Image capture of 31 patients with gout by Philips brilliance 16 rows CT scanner and analysis of joint characteristics.

Results: The average density of tophus was 158 ± 65 Hounsfield units. The diameter of bony destruction was correlated with the diameter of surrounding tophus (r=0.83, p<0.01). The CT value of tophus was associated with the course of gout (r=0.51, p<0.01), and the CT value of tophus was related to the mean levels of five-year serum uric acid (r=0.49, p<0.05).

Conclusion: Combining clinical and laboratory tests, the characteristic CT features of gouty arthritis can help correctly diagnose gout arthritis.
