目的 研究16排螺旋CT血管成像 在妇科盆腔肿瘤患者诊断中的应用价值。 方法 选取2012年5月至2016年1月我院收 治的女性盆腔肿瘤患者112例为研究对 象，均行16排螺旋CT血管成像检查，根 据病理结果将其分为恶性肿瘤组(n=62) 及良性肿瘤组(n=50)，分析CT诊断妇科 盆腔肿瘤的灵敏度、特异度及准确度， 采用PHILIPS Extended BrillianceTM workspace V4.0工作站对扫描图像进行处 理，观察良恶性肿瘤的CT影像特征，比较 良恶性肿瘤组CT图像显示的肿瘤边界、盆 腔淋巴结肿大情况，并根据所得灌注图像 分析其血流(BF)、血容(BV)、毛细血管通 透性(PS)。结果 CT诊断妇科盆腔肿瘤的 灵敏度为74.19％，特异度为72.00％，准 确度为73.21％；16排螺旋CT血管成像结 果显示妇科盆腔肿瘤肿块呈实性、囊性及 实囊混合性，其中实性肿块表现为软组织 密度，亦有脂肪密度肿块，向囊内突起呈 结节状，内可见脂肪、毛发及钙化，钙 化肿块表现为点、片、环状及结节状， 未成熟性畸胎瘤表现为较多散在分布的 片状及块状钙化；恶性肿瘤组CT影像边 界不清晰比例91.90％、伴盆腔淋巴结肿 大比例85.48％及BF(150.26±3.11)ml/ min·100g、BV(6.38±1.26)ml/100g、 PS(18.16±1.54)ml/min·100g明显高于 良性肿瘤组(P<0.05)。结论 16排螺旋CT 血管成像对妇科盆腔肿瘤具有具有较高的 诊断价值，尤其是恶性肿瘤，值得在临床 推广应用。

Objective to study the row helical CT angiography in the diagnosis of pelvic tumors of department of gynaecology application value. Methods Selection in May 201 to January 201, 112 cases of female pelvic tumor patients of our hospital as the research object, row helical CT angiography in imaging, according to the pathological results will be divided into the malignant tumor group (n=62) and benign tumor group (n=50), and analyze the sensitivity of CT in the diagnosis of pelvic tumors of department of gynaecology, specific degrees and accuracy, and USES the workstation to scan image processing, to observe the CT imaging features of benign and malignant tumor is benign and malignant tumor group CT images showed the tumor boundary, pelvic lymph node enlargement, and according to the perfusion image analysis its blood flow (BF), blood volume (BV), capillary permeability (PS). Results the sensitivity of CT in the diagnosis of pelvic tumors of department of gynaecology is 74.19%, 72.00%, the accuracy is 73.21%. Row helical CT angiography showed a solid lump of department of gynaecology pelvic tumor and cystic and solid cystic mixed, in which the solid mass of soft tissue density, also has a fat density lump, nodules is raised within the sac, fat, hair, calcification, can be seen in the calcified mass point for the performance of films, annular and nodular, not maturity teratoma is more scattered distribution of flake and massive calcification; CT image boundary unclear malignant tumor group 91.90%, 85.48% with pelvic lymph node enlargement and BF (150.26±3.11) ml/min, 100g, BV ml/100g (6.38 1.26 mm), PS (18.16±1.54) ml/min, 100g significantly higher than in benign group (P<0.05). Conclusion Row helical CT angiography for gynecological pelvic tumors is has high diagnostic value, especially malignant tumor, is worth popularizing in clinical application.
