Abstract

Objective To investigate the diagnostic evaluation of 64-slice CT angiography(CTA)technique on the intracranial aneurysm in patients with nontraumatic subarachnoid hemorrhage(SAH).Methods 48 patients with nontraumatic SAH were received CTA.The original images were studied,and the VR,MIP,MPR(cMPR)techniques were used to reconstruct the images.All the patients CTA results were compared with those of DSA and(or)operation.Results Of all the 48 patients,39(39/48)patients with aneurysms were detected.The results of DSA and operation were identical to those of CTA.Conclusion 64-slice spiral CTA has very high sensitivity,specificity,and accuracy in detecting aneurysms,and maybe replace conventional DSA.
