【摘要】：目的探讨双源CT(DECT)双能量成像诊断痛风患者尿酸盐沉积结晶的临床效果。方法对90例疑似痛风的患者行DECT检查及病变部位穿刺活检检查,观察DSCT检测痛风性尿酸盐沉积的特异性、敏感性、假阳性率、假阴性率、阳性预测值及阴性预测值,并对病变发生部位作统计。结果 (1)DECT检测痛风性尿酸盐沉积的的敏感性为95.23%,特异性为91.66%,假阴性率为4.76%,假阳性率为8.33%,阳性预测值为90.90%,阴性预测值为95.65%;(2)本研究应用DECT所检出的44例痛风尿酸盐沉积结晶患者共发现结晶沉积132处,部位在双足58处,占43.9%;双膝50处,占37.9%;双手22处,占16.7%;双肘2处,占1.5%。结论 DECT能够准确快捷地对痛风患者尿酸盐沉积结晶做出诊断,可作为临床筛查痛风病的重要辅助检查之一。
[Abstract]:Objective to investigate the clinical effect of dual-source CT-DECT dual-energy imaging in the diagnosis of uric acid deposition crystallization in patients with gout. Methods 90 patients with suspected gout were examined by DECT and biopsy of lesion site. The specificity, sensitivity, false positive rate, false negative rate, positive predictive value and negative predictive value of gouty uric acid deposition were observed by DSCT. Results the sensitivity, specificity and false negative rate of DECT in detecting the deposition of gouty uric acid were 95.233.The specificity was 91.66and the false negative rate was 4.76%. The false positive rate was 8.33, the positive predictive value was 90.90, the negative predictive value was 95.65; (2) in this study, DECT was used to detect a total of 132 crystals in 44 cases of gout uric acid deposition, the location of which was 58 in the two feet (43.9%). 50 knees (37.9%); 22 hands, 16.7; Conclusion DECT can accurately and quickly diagnose uric acid deposition crystallization in patients with gout, and can be used as one of the important auxiliary examinations in clinical screening of gout.
