Objectives:To evaluate the diagnostie value of 16 row helical CT with application of volume viewer. Methods:A retrospective analysis of 52 patienis’numerical data was made. All patients with clinical suspected cerebral vessels disease were detected by the 16 row helical CT angiography with application of voltume viewer

and the imaging data were compared with those of DSA or pathology. Results:of 52 cases

a total of 33 intracranial aneurysms were detected by the application of volume viewer

which clearly displayed the body

neck and parenl artery of intracranial aneurysms

and showed the aneurysms relation with peripheral vessels and cranioaural. In 52cases

8 cases of cerebral vascular malformations showed Ihe form

the size and the hemisphere of cacogenesis cerehral vessels

as well as the amount of feeding artery and draining vein. In 2 case Moyamoya disease

16 row helical CT angiography showed paragraph of obliteration Cerebral vessels and branch stem paraplasm. Conclusion:There is clinical application value in 16 row helical CT angiography for the diagnosis of cerehral vessels disease

which provides guidance fur clinical treatment.
