Abstract:
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.
