The Application of Multislice Computed tomography Virtual Endoscopy in Aortic and Iliac Artery Diseases / 实用放射学杂志

ABSTRACT

Objective To discuss the clinical values of virtual endoscopy (VE) using multislice computed tomography (MSCT) in diagnosis of the aorta and iliac artery diseases.Methods MSCT angiography in 36 cases suspected of the aorta and iliac artery diseases and 40 cases underwent abdominal examination were performed, then all CT virtual endoscopy (CTVE) were obtained at the vessel with suspected lesions on work-station, and the relations between the quality of images and scanning parameters were observed.Results All internal and dual-cavity were seen in 10 cases of aortic dissection; enlarged cavity of aneurysm were showed in 16 aortic aneurysms. Calcification plaques were displayed in 48 cases. One endograft and one postoperative aorta were seen the morphology and the location of stenosis. One case of iliac artery obstruction was displayed obstructive cavity on the image of CT virtual endoscopy.Conclusion The quality of CT virtual endoscopy is related to the scanning technique,scanning parameters, motion aritiact. CT vitrtual endoscopy is the important complementary to maximum intensity projection, multiplannar reformation, surface shadow display, and axial images, and has high value in the diagnosis, treatment, and follow-up of the aortic diseases
