目的：探讨64排螺旋 CT 对盆腔急腹症的诊断价值。方法选取2010年1月至2015年12月诊治的107例急腹症患者，经手术病理证实或临床确诊为盆腔病变，分析64排螺旋 CT 检查的病变发现率及诊断符合率。结果107例患者 CT 共检出病变105例：泌尿系病变52例、妇科病变49例、肠道病变4例，漏诊2例泌尿系结石，误诊4例妇科病变，病变检出率为98.1%（105/107），诊断符合率为94.3%（101/107）。结论 CT 扫描对于盆腔急腹症病变检出率及诊断符合率均较高，有重要的临床价值。“,”Objective To study the value of 64-slice spiral CT in diagnosis of pelvic acute abdomen. Methods From January 2010 to December 2015,107 cases of patients with acute abdomen for diagnosis and treat-ment were selected,they were confirmed by surgery and pathology or clinical diagnosis of pelvic lesions. The lesion de-tection rate and the etiological diagnostic accuracy of the 64-slice spiral CT examination was analyzed. Results A total of 107 cases of CT were detected in 105 patients:urinary tract lesions in 52 cases,gynecological diseases in 49 cases, intestinal lesions in 4 cases. Miss diagnosis of urological stone in 2 cases,misdiagnosis of 4 cases of gynecological disea-ses. The lesion detection rate was 98. 1%( 105 / 107 ),and the etiological diagnostic accuracy was 94. 3%(101/ 107). Conclusion CT scanning for pelvic acute abdomen lesion detection rate and diagnosis rate were higher,it has important clinical value.
