目的 对比MR、CT鉴别与诊断卵 巢子宫内膜异位囊肿效用，评价CT诊断价 值。方法 选取2011年1月至2015年10月我 院收治确诊的200例卵巢囊性病变的患者 患者作为研究对象，均进行CT、MR诊断， 比较二者的诊断价值。结果 子宫内膜异 位囊肿占38.5%、成熟性畸胎瘤26.0%、浆 液性囊腺瘤17.5%、单纯性囊肿11.0%、粘 液性囊腺瘤7.0%；子宫内膜异位囊肿双侧 发病比重高于其他类型异位囊肿，子宫内 膜异位囊肿年龄低于卵巢囊肿，子宫内膜 异位囊肿长径低于成熟畸胎瘤、浆液性 囊腺瘤、粘液性囊腺瘤，高于单纯性囊 肿，差异具有统计学意义(P＜0.05)；MR 诊断敏感度89.61%、特异度91.06%、阳性 预测值86.25%、阴性预测值93.33%、符合 率90.50%，CT诊断则为90.91%、88.62%、 83.33%、93.97%、89.50%，差异无统计 学意义(P＞0.05)；研究中“卫星囊”占 51.95%、有囊内高密度影病灶11.69%、囊 壁增厚25.97%、囊性包块10.39%，粘连占 18.18%，假阴性7例，其中粘连3例、囊性 包块3例、囊壁增厚1例，差异无统计学意 义(P＞0.05)。结论 CT鉴别诊断卵巢子宫 内膜异位囊肿效果与MR相近，诊断效用较 MR无明显优势。

Objective To compare the effectiveness of MR and CT in the diagnosis and diagnosis of ovarian endometriosis cyst, and to evaluate the diagnostic value of CT. Methods Two hundred cases of patients with cystic lesions of the ovary from January 2011 to October 2015 were diagnosed in the hospital as the research object, all of which were diagnosed by CT and MR. Results The endometrial cyst accounted for 38.5%, teratoma 26%, 17.5% serous cystadenoma, 11% simple cysts, 7% mucinous cystadenoma, endometrial cyst of bilateral disease proportion is higher than other types of cysts, endometriosis cyst under the age of ovarian cyst, endometriosis cyst diameter lower than mature teratoma, serous cystadenoma above, mucinous cystadenoma, simple cyst, the difference was statistically significant (P<0.05). MR diagnostic sensitivity 89.61%, specificity 91.06%, positive predictive value of 86.25% and negative predictive value of 93.33%, the coincidence rate was 90.50%, CT was 90.91%, 88.62%, diagnosis of 83.33%, 93.97%, 89.50%, the difference was not statistically significant (P>0.05), in the study of "satellite capsule" accounted for 51.95%, sac high density lesions in 11.69%, cystic wall thickening in 25.97%, cystic mass in 10 39%, adhesion accounted for 18.18%, false negative in 7 cases, of which 3 cases of adhesion, cystic mass in 3 cases, 1 cases of cystic wall thickening, the difference was not statistically significant (P>0.05). Conclusion CT differential diagnosis of ovarian endometriosis cyst is similar to MR, and the diagnostic utility of MR has no obvious advantage.
