摘要
目的 :分析卵巢肿瘤的CT表现 ,提高CT诊断卵巢肿瘤的准确性。材料和方法 :分析我院经手术病理证实的 5 3例卵巢肿瘤 (其中良性 2 2例 ,恶性 2 5例 )与 6例肿瘤样病变的CT表现。结果 :良性卵巢肿瘤CT检出 2 1例 (检出率为95 .5 % ) ,术前CT诊断为良性肿瘤 19例 (准确率 86.4% ) ;CT检出恶性肿瘤 2 2例 (检出率 88% )。术前CT诊断恶性 2 0例(准确率 80 % ) ;肿瘤样病变 6例 ,CT全部检出 ;所有的病例 ,CT检出率为 92 .5 % ,良恶性定性准确率为 84.9%。结论 :CT能清晰显示盆腔结构 ,可提供对肿瘤的定位、定性、病变范围的可靠信息。
Purpose: To analysis CT manifestation and to improve CT diagnostic accuracy of ovarian neoplasm. Materials and Methods: CT manifestations of 53 cases with ovarian masses in our hospital were carefully analyzed. Of all the 53 cases, 22 cases were benign tumors and 25 cases malignant ones and 6 cases tumor-like lesions. All of them were proved by surgery and pathology. Results: CT scans showed that benign tumors was in 21/22 cases, the detecting rate was 95.5%. 19 cases were diagnosed as benign tumor before surgery, the accuracy of diagnosis was 86.4%. Of all 25 malignancies, CT detected 22 cases; the detecting rate was 88%. 20 cases were diagnosed as malignancies, the accuracy of diagnosis was 80%. CT detected all 6 cases tumor-like lesion. Of all cases, the detected rate was 92.5%, diagnostic accuracy of benign and malignancy was 84.9%. Conclusion: CT can display pelvic structure clearly; it can provide reliable information about site, qualitative analysis, and extension of ovarian neoplasm as well.
