Abstract: ［Abstract］ Objective Research and sum up of clinical application of MSCTA in diagnosis of cerebral aneurysms. Methods The clinical data of 60 patients with suspected subarachnoid hemorrhage who underwent MSCTA in our hospital from October 2014 to January 2017 were selected, Among them, 15 cases underwent conservative treatment, and the remaining 45 cases underwent MSCTA got surgical treatment, which including 41 cases underwent DSA endovascular treatment and 4 cases underwent craniotomy. The diagnostic accuracy, application value and the author’s experience of CTA were analyzed. Results A total of 47 cerebral aneurysms were diagnosed by MSCTA in 45 patients, while 49 cerebral aneurysms were detected by DSA and craniotomy. The diagnostic coincidence rate was 95.9%. There was no significant difference between CTA and DSA that used to analyze the long axis of the tumor, the short axis of the tumor, and the neck of the tumor, P>0.05. Conclusion For patients with intracranial aneurysms, the detection of MSCTA has important clinical significance. It is helpful, safe and reliable to show the tumor size and neck of the patients intracranial aneurysm.
