Abstract:
Objective To observe the value of dual-energy CT(DECT)for diagnosing knee gouty arthritis(GA)complicated with knee osteoarthritis(KOA).Methods Forty-eight cases of GA(GA group),30 cases of KOA(KOA group)and 60 cases of GA complicated with KOA(GA+KOA group)were retrospectively enrolled.Clinical and imaging data were compared among 3 groups and between each 2 groups,and the efficacy of DECT for diagnosing knee GA complicated with KOA was analyzed.Results Significant differences of detection rate and CT value of bone marrow edema(BME)were found among 3 groups and between each 2 groups(all P＜0.05),also of the course of disease,serum uric acid(SUA),monosodium urate(MSU)volume,bone erosion score and CT value between GA group and GA+KOA group(all P＜0.05).The area under the curve(AUC)of bone erosion score and CT value for diagnosing knee GA complicated with KOA was 0.779 and 0.824,respectively,and of the combination of the above 5 indexes was 0.898,higher than that of each parameter alone(all P＜0.05).Conclusion DECT was helpful for diagnosing knee GA complicated with KOA,and further combining with clinical parameters could improve its diagnostic efficacy.
