目的：探讨卵巢肿瘤的ＣＴ诊断的价值。方法：对２３例经手术病理证实的卵巢肿瘤的ＣＴ表现进行回顾性分析。结果：本组ＣＴ诊断正确率为７２．４％。良性肿瘤绝大多数表现为边界光整的薄壁囊性肿块。囊内脂肪密度、牙齿和钙化等是囊性畸胎瘤的特征性表现；细而规则的分隔则是囊腺瘤的ＣＴ特点。恶性肿瘤呈实质性和混合性，肿块边缘不光整，增强后实质强化明显，并且多见盆腹腔转移。结论：ＣＴ对卵巢肿瘤的诊断很有价值
Objective: To explore the value of CT diagnosis of ovarian tumors. Methods: The CT findings of 23 cases of ovarian tumors confirmed by surgery and pathology were analyzed retrospectively. Results: The CT diagnosis rate of this group was 72.4%. The vast majority of benign tumors appear as thin-walled cystic masses with well-defined borders. Intracapsular fat density, teeth and calcification are characteristic features of cystic teratoma; fine and regular separation is CT features of cystic adenomas. Malignant tumors were substantial and mixed, and the margins of the tumors were not smooth. After the enhancement, the enhancement of the tumors was obvious, and the pelvic peritoneal metastases were more common. Conclusion: CT is valuable in the diagnosis of ovarian tumors
