目的:研究卵巢相关解剖结构在识别正常卵巢及对卵巢源性与非卵巢源性肿瘤的鉴别诊断价值。方法观察正常卵巢组12例(24侧)三个年龄组(每组4例)其正常卵巢的形态学特征及相关解剖结构。回顾性研究40例盆腔肿块患者,其中28例为卵巢源性肿块,以术后病理为标准,评价各CT征象在鉴别卵巢源性与非卵巢源性肿瘤中的价值。结果正常卵巢组院不同年龄组的卵巢形态特征有差异,但尚无统计学意义。两侧卵巢静脉在CT显示清晰,MDCT可清晰地显示卵巢悬韧带21侧(21/24),阔韧带4侧,显示率的差异具有显著的统计学意义(=0.000)。盆腔病变组院以卵巢血管蒂征阳性判断卵巢源性肿瘤的准确率为85.0豫,灵敏度为89.3豫,特异性为75.0豫,阳性预测值为89.3豫,阴性预测值为75.0豫。以病侧无正常卵巢显示判断卵巢源性肿瘤的准确率为87.5豫,灵敏度为100.0豫,特异性为58.3豫,阳性预测值为84.8豫,阴性预测值为100.0豫。联合上述两个征象,可进一步提高鉴别的准确性院准确率92.5豫,灵敏度96.4豫,特异性83.3豫,阳性预测值93.1豫,阴性预测值90.9豫。结论多排CT识别正常卵巢对鉴别卵巢源性与非卵巢源性肿瘤中有重要价值。

Objective To evaluate the value of ovarian anatomical structures in multidetecter computed tomography (MDCT)in dif erentiating ovarian tumors from non-ovarian masses. Methods The morphology and anatomical structures of normal ovarians with 12 patients(24 sides)and three age groups(n=4 per group)were observed.40 cases with pelvic masses included 28 ovarian tumors proved by surgery and pathology were reviewed retrospectively and the CT characteristics were analyzed.Results There are dif erences between ovarian morphology in dif erent age groups,but there is no statistical y significant.CT can clearly show the ovarian vein.MDCT can clearly show the suspensory ligament of the ovary in 21 cases (21/24),while broad ligament 4 cases,with significant statistical significance ( =.000).If the ovarian vascular pedicle sign was used for determining whether the tumor was from the ovary or not,the accuracy,sensitivity,specificity,positive predictive value and negative predictive value was 85.0%,89.3%,75.0%,89.3%and 75.0%respectively.If the identification of no normal ovary was used to determine ovarian origin of the tumor,the accuracy,sensitivity,specificity, positive predictive value and negative predictive value was 87.5%,100.0%,58.3%,84.8%and 100.0%respectively.Combined with both signs,it can improve the accuracy of identification,the accuracy, sensitivity,specificity,positive predictive value and negative predictive value was 92.5%,96.4%,83.3%,93.1%and 90.9%respectively.Conlusion MDCT is very helpful in identifing normal ovaries when dif erentiating ovarian tumors from non-ovarian masses.
