目的 评价双能量CT(DECT)痛风识别技术在检测痛风患者尿酸盐结晶沉积中的应用.方法 回顾性分析108例近2周发作过单关节肿和(或)痛患者的患肢关节双能量CT扫描资料,其中符合美国风湿病学会(ACR) 1977年分类标准的痛风患者95例,非痛风组13例.95例痛风患者双能量CT扫描后得到的双能0.3比例融合图像组作为常规组；所获得的80 kV及140 kV图像输入痛风识别软件,后处理获得的伪彩图像组作为后处理组.观察常规组与后处理组发现的尿酸盐结晶,并采用x2检验比较；比较两组发现尿酸盐结晶的敏感度和准确率,并采用x2检验进行比较.结果 常规组中有51例患者能显示软组织内尿酸盐结晶,显示病灶的部位共298处；13例非痛风患者中有2例显示高密度结晶；常规组发现尿酸盐结晶的敏感度为53.7％,特异度为84.6％,准确率为57.4％.后处理组中69例患者发现散在的绿色的尿酸盐结晶,显示病灶的部位共401处；13例非痛风患者均未显示绿色的尿酸盐结晶；后处理组发现尿酸盐结晶的敏感度为72.6％,特异性为100.0％,准确率为75.9％.两组发现尿酸盐结晶的病灶数差异有统计学意义(x2=5.193,P＜0.05),发现尿酸盐结晶的敏感度和准确率差异也有统计学意义(x2值分别为7.329和8.333,P值均＜0.05).结论 DECT痛风识别技术能发现更多部位、更小体积的尿酸盐结晶,在痛风早期诊断、监测治疗疗效中有潜能.
目的 評價雙能量CT(DECT)痛風識彆技術在檢測痛風患者尿痠鹽結晶沉積中的應用.方法 迴顧性分析108例近2週髮作過單關節腫和(或)痛患者的患肢關節雙能量CT掃描資料,其中符閤美國風濕病學會(ACR) 1977年分類標準的痛風患者95例,非痛風組13例.95例痛風患者雙能量CT掃描後得到的雙能0.3比例融閤圖像組作為常規組；所穫得的80 kV及140 kV圖像輸入痛風識彆軟件,後處理穫得的偽綵圖像組作為後處理組.觀察常規組與後處理組髮現的尿痠鹽結晶,併採用x2檢驗比較；比較兩組髮現尿痠鹽結晶的敏感度和準確率,併採用x2檢驗進行比較.結果 常規組中有51例患者能顯示軟組織內尿痠鹽結晶,顯示病竈的部位共298處；13例非痛風患者中有2例顯示高密度結晶；常規組髮現尿痠鹽結晶的敏感度為53.7％,特異度為84.6％,準確率為57.4％.後處理組中69例患者髮現散在的綠色的尿痠鹽結晶,顯示病竈的部位共401處；13例非痛風患者均未顯示綠色的尿痠鹽結晶；後處理組髮現尿痠鹽結晶的敏感度為72.6％,特異性為100.0％,準確率為75.9％.兩組髮現尿痠鹽結晶的病竈數差異有統計學意義(x2=5.193,P＜0.05),髮現尿痠鹽結晶的敏感度和準確率差異也有統計學意義(x2值分彆為7.329和8.333,P值均＜0.05).結論 DECT痛風識彆技術能髮現更多部位、更小體積的尿痠鹽結晶,在痛風早期診斷、鑑測治療療效中有潛能.

Objective To evaluate the clinical value of dual-energy CT in the detection of monosodium urate crystals in patients with gout.Methods One hundred and eight patients who experienced unilateral arthrocele and (or) joint pain in the past two weeks were enrolled into our study.DECT were performed for the upper or lower extremity.Ninety-five patients were enrolled into the gout study group based on the American rheumatism association (ACR) classification standard;The 0.3 linear blended images group were regarded as conventional CT group,DE (80 kV and 140 kV) datasets were reconstructed via gout-recognition software,the pseudo-color images group as the postprocessed group.Imagings were reviewed independently by two senior radiologists.Chi-square test were used for statistical analysis with the SPSS 13.0software.Results In the conventional CT group,DECT scans revealed a total of 298 areas of urate deposition in 51 patients;The sensitivity,specificity,and accuracy were 53.7％,84.6％,and 57.4％.In the postprocessed group,401 areas of green urate deposition were detected in 69 patients,the sensitivity,specificity,and accuracy were 72.6％,100.0％,75.9％ respectively,the differences had statistical significance (x2 =7.329 and 8.333,P ＜ 0.05).Conclusions DECT gout recognition technology can detect smaller amount of monosodium urate in the other parts of the body,with a great potential in early diagnosis and treatment monitoring of patients with gout.
