Abstract Objective: To evaluate the value of 16-slice CT angiography technique in the treatment of intracranial aneurysm. Materials and Methods: Thirty-eight cases of patients with intracranial aneurysm during June 2007 to June 2009 were reviewed, all cases were performed MSCT angiographies before and after surgery, DSA were performed in all cases before surgery and 4 cases after surgery. Pre- and post-operation MSCT angiography were performed within 10 days in 32 cases, and within 11～27 days in 6 cases. Result: There were 46 intracranial aneurysms in 38 patients; Clipping 40 aneurysms in 34 patients; embolysing aneurysms in 4 cases; another two were not treated. Forty aneurysms were diagnosed correctly by CTA, but 5 lesions were suspicious, and 1 lesion was missed. Two incomplete occlusions were found by post-operative CTA, residual neck was found in 1 case. Conclusion: 16-slice CTA was a non-invasive, effective and accurate method to evaluate the intracranial aneurysm and it could be easily accepted by patients. It has advantages not only in diagnosis of the intracranial aneurysms, preoperative selection of treatment, also in the postoperative follow-up of the intracranial aneurysm.
