摘要
目的:探讨多排螺旋CT子宫动脉血管成像术(CTA)在子宫肌瘤血管显像中的应用。方法:27例经手术病理证实的子宫肌瘤患者,于术前行盆腔CT平扫及增强后子宫动脉CTA成像,CTA原始数据采用多平面重建(MPR)、容积再重建(VR)、最大密度投影(MIP)等技术进行处理,由2名有经验的放射科医师对子宫肌瘤中子宫动脉及其分支显示部位及情况进行判断。结果:27例子宫肌瘤患者CTA图像均清晰显示增粗、迂曲的子宫动脉,13例子宫壁间肌瘤及6例浆膜下肌瘤可见子宫动脉分支形成的网状血管丛包绕瘤体,2例子宫黏膜下肌瘤血管丛不明显;14例子宫肌瘤患者肌瘤由双侧子宫动脉供血,瘤体主要位于宫体和宫底,非主瘤体侧可见子宫动脉形成少许分支参与供血。结论:多排螺旋CT子宫动脉CTA可以清晰显示子宫动脉及其在子宫肌瘤中血管网的分布特征。
Objective： To investigate the application of multi-slice spiral CT uterine artery CTA on diagnosis of hysteromyoma angiography. Methods： Twenty-seven surgically and pathologically proved hysteromyoma patients were performed pre-surgery pelvic CT scan and enhanced uterine artery CTA imaging. CTA original data were processed by multiplanar reformation（ MPR）,volume rebuild（ VR）,maximum intensity projection（ MIP）. Two experienced radiology doctors carried out analysis on uterine artery and branches display parts as well as conditions. Results： CTA image of 27 hysteromyoma patients clearly demonstrated enlarged and circuitous urine artery. 13 cases of intramural myoma of uterus and 6 cases of subserous myoma were visible for uterine artery branches formed reticular vein plexus wrapping tumor body; 2 cases of submucosal myoma vein plexus are not obvious; muscle tumor of 14 hysteromyoma patients got blood supply from both sides uterine artery,while tumor body mainly located in uterine body and fundus uteri; uterine artery formed a few branch participated in blood supply at non-major tumor body side. Conclusions： Multi-slice spiral CT uterine artery CTA could clearly demonstrate distribution characteristics of uterine artery and its vascular net in hysteromyoma angiography.
