Application of 64 Multi-slice CT Angiography for Etiological Factors of Subarachnoid Hemorrhage

Objective:To explore the clinical application of 64 multi-slice CTA(MSCTA) for etiological diagnosis of spontaneous subarachnoid hemorrhage.Methods:76 patients were clinically diagnosed as spontaneous subarachnoid hemorrhage,they were examined by 64 MSCTA and by DSA or operation.The results of CTA were compared with those of DSA or operation.Results:Of the 76 patients examined by CTA,28 were diagnosed as having cerebral aneurysms proved by DSA and the operation,and 3 were diagnosed as having AVM proved by DSA and the operation.Conclusion:64 MSCTA is one of the choices in early etiological diagnosis for spontaneous subarachnoid hemorrhage.
