The Value of Dual-source CT Dual-energy Imaging in the Diagnosis of Gouty Arthritis

Objective: To explore the diagnostic value of DSCT in gout arthritis. Methods: Scanning 160 patients with arthritis joint in our hospital using dual-source CT with dual-energy and taking advantage of the configuration instrument with gout recognition software to process the original image, there were two experienced clinical imaging doctors with high qualifications analyzing the obtained images to determine whether there was urate crystal deposition within patients' inspection area. Subsequently, through following up cases and comparing with clinical diagnosis, they analyzed the accuracy of DSCT technique for the screening, early diagnosis and differential diagnosis of gout. Results: In the DSCT examination of those 136 patients with gout, 124 cases were found in the joints with urate crystal deposition and the detection rate of gout was 124/136 (91.2%). Among those patients, 28 out of 33 who have acute arthritis, were found by DSCT examination that there was uric acid deposition in their affected joint, and the detection rate of early gout was 28/33 (84.8%). Within 24 patients with non-gout, 24 were not found to have urate crystal deposition. Conclusion: Scanning the pathogenesis of arthritic patients using DSCT technique could effectively improve the accuracy of screening, early diagnosis and differential diagnosis of gout.
