【摘要】：目的探讨双能量CT(DECT)处理技术对痛风性关节炎尿酸盐结晶沉积的诊断价值。方法收集常州市第二人民医院收治的190例痛风性关节炎患者的临床资料,所有患者入院后均接受DECT检查,且临床及影像学资料完整,分析DECT对痛风性关节炎尿酸盐结晶沉积的诊断价值。结果观察组DECT扫描见尿酸盐结晶沉积171例,诊断敏感性为90.00%;171例DECT均可见尿酸盐沉积,见弥漫性绿色影,共发现542处,主要分布于四肢关节及附近结缔组织内,双足及踝关节、膝关节、双手及腕关节及肘关节病灶数分别为321、206、12及3处;尿酸盐结晶沉积最长径线5 mm尿酸盐结晶共417处(76.94%),5~10 mm共108处(19.93%),10 mm共17处(3.14%);结晶形态多数不规则,部分呈点状。结论双能量CT对痛风性关节炎尿酸盐结晶沉积检测率高,与病理穿刺一致性高,且对非典型部位尿酸盐结晶沉积显示率高,可为痛风性关节炎患者临床诊疗提供依据。
[Abstract]:Objective to investigate the diagnostic value of dual-energy CT-DECT in the diagnosis of uric acid deposition in gouty arthritis. Methods the clinical data of 190 patients with gouty arthritis treated in the second people's Hospital of Changzhou City were collected. All the patients were examined by DECT after admission, and the clinical and imaging data were complete. The diagnostic value of DECT in the diagnosis of uric acid crystal deposition in gouty arthritis was analyzed. Results in the observation group, 171 cases of uric acid crystal deposition were found on DECT scan. The diagnostic sensitivity was 90. 000% and 171 cases of DECT showed uric acid deposition and diffuse green shadow. A total of 542 sites were found in the joints of limbs and adjacent connective tissues, the joints of both feet and ankles, and the knee joint. The number of lesions in hands, wrist joint and elbow joint were 321 ~ 206 ~ 12 and 3, respectively, the longest track of uric acid crystal deposition was 5 mm and 5mm, total 417 of 5mm uric acid crystal, 108 lesions of 10 ~ 10 mm and 10 ~ (10) mm, 17 ~ 3.14 ~ (th) of 10 mm ~ 10 mm ~ 10 mm ~ (10) ~ (10 mm), most of which were irregular in shape. Conclusion Dual-energy CT has a high detection rate for uric acid deposition in gouty arthritis, which is consistent with pathological puncture, and has a high display rate for uric acid crystal deposition in atypical sites. It can provide basis for clinical diagnosis and treatment of gouty arthritis.
