目的探讨64层螺旋CT血管成像技术在腹腔巨大肿瘤供血起源诊断中的价值.方法收集腹部巨大肿瘤患者共20例,肿瘤直径平均17.8 cm,患者均接受64层螺旋CT平扫及增强扫描,在飞利浦工作站上,对传入的原始数据进行多平面重建(MPR)、最大密度投影(MIP)、三维容积再现(VR)等后处理技术重建肿瘤血管,由2名主治医师通过观察肿瘤供血动脉,判断肿瘤起源,并以手术病理检查结果为标准.结果 20例患者中,恶性肿瘤15例,良性肿瘤5例,显示肿瘤血管19例,共36支血管.发现侧支性血供6例,动静脉分流4例.18例CT血管成像技术所见与手术病理结果完全吻合,准确率为90％,1例未显示肿瘤血管,1例误诊.结论多层螺旋CT通过显示腹部肿瘤的供血动脉,对腹部巨大肿瘤在术前诊断中具有较大的临床价值.

Objective To investigate the value of 64-slice spiral CT angiography in diagnosis of the origin of abdominal large masses.Methods Twenty patients who were proven by operation and pathology to be abdominal massive tumor were collected in this study,tumor diameter average 17.8cm.All patients accepted plain and enhanced CT scanning,and their data were transferred to Philips IntelliSpace Portal.The tumor vessel were reconstructed with multiplanar reformation(MPR),maximum intensity projection(MIP),and volume rendering(VR).The origin of tumor were judged according to the feeding arteries by 2 attending physician,and the results were compared with pathology.Results Of these 20 cases,15 cases were malignant tumor,5 benign.Blood supply arteries were found in 19 patients,36 vessels.Lateral branch vessels in 6 cases and arteriovenous fistula in 4 cases.MSCTA findings were consistent with operation and pathology,with the accuracy of 90％.One case had no tumor vessel,one was misdiagnosed.Conclusion MSCT could be taken good use in diagnosis of large abdominal masses by tracking down the nourishing artery of masses.
