卵巢肿瘤64层螺旋CT影像学表现及其鉴别诊断分析

目的使用64层螺旋CT(MSCT)对卵巢肿瘤患者进行检查,分析其影像学表现及鉴别诊断价值。方法回顾分析本院2017年9月至2019年7月收治的72例卵巢肿瘤患者的临床资料,所有患者均进行MSCT检查。对患者MSCT影像学表现进行分析,并以病理检查为基准,对MSCT诊断正确率进行比较。结果MSCT对畸胎瘤、卵泡膜细胞瘤、纤维瘤、粘液性腺癌、浆液性囊腺癌的诊断正确率分别为97.14%、86.66%、91.66%、100%、100%,总正确率为94.44%,与病理结果比较差异无统计学意义(P>0.05);良性患者MSCT图像肿瘤性质多为囊性,壁与间隔较薄且厚薄均一,增强扫描囊性者,壁及间隔均匀强化,轻强度化,病灶内密度不均匀。恶性肿瘤其可向周围组织侵犯,囊性者多见软组织成分,壁及间隔不规则增厚,增强扫描不均匀明显强化,常伴腹水。结论MSCT检查可清晰显示不同卵巢肿瘤病变形态、内部结构、周围组织关系以及转移情况,对卵巢肿瘤诊断正确率高。

Imaging Features of Ovarian Tumors in 64-Slice Spiral CT and Their Differential Diagnosis

Objective Patients with ovarian tumors were examined with 64-slice spiral CT(MsCT),and their imaging features and its differential diagnostic value were analyzed.Methods The clinical data of 72 patients with ovarian tumor admitted to our hospital from september 2017 to July 2019 were retrospectively analyzed.All patients underwent MsCT.The MsCT imaging characteristics of the patients were analyzed,and the diagnostic accuracy of MsCT was compared based on pathological examination.Results The diagnostic accuracy of MsCT for teratoma,thecoma,fibroid,mucinous adenocarcinoma,serous cystadenocarcinoma was 97.14%,86.66%,91.66%,100%,100%,and the total correct rate was 94.44%.There was no significant difference from the pathological results(P>0.05).In MsCT images of benign patients,the tumors were mostly cystic,and the wall and the gap were thin and the thickness was uniform.After the enhanced scan,it showed the person with cystic tumors,the wall and the gap were evenly strengthened.The density in the lesion was not uniform.Malignant tumors invade to surrounding tissues.The patients with cystic tumors often can be seen with components of soft tissue.The wall and gap were irregularly thickened,and the enhanced scan showed uneven enhancement and was often accompanied by ascites.Conclusion MsCT examination can clearly show the shape,internal structure of different ovarian tumors,relationship with surrounding tissue and metastasis,and diagnostic accuracy for ovarian tumors is high.
