Study on Sensitivity and Accuracy of Diagnosis of Intracranial Aneurysms Based on 256-Slice Spiral CT Angiography

Objective: To investigate the value of 256-slice spiral CT angiography in the diagnosis and postoperative evaluation of patients with intracranial aneurysms. Methods: A total of 62 patients with intracranial aneurysms diagnosed by neurosurgery in our hospital were randomly collected from 2017.03–2018.11. The MSCTA was performed by labeling intravenous non-ionic contrast agent (iodosyls alcohol). The obtained image was imageprocessed at Sun's stand-alone workstation (Philip256iCT). Observe the position, shape, size of the aneurysm, the relationship between the neck and the artery and the structure of the skull base, and compare with the intraoperative findings to understand the anastomosis between the preoperative and intraoperative. Postoperatively, 28 cases were reviewed, and the surgical results, the patency of the arterial artery, and the presence or absence of aneurysm residual were confirmed. Results: Sixty-two patients with intracranial aneurysms were diagnosed with MSCTA and DSA. A total of 66 aneurysms and multiple aneurysms were found. Of these, 32 patients underwent direct operative MSCTA and 43 underwent craniotomy. Endovascular interventional therapy. The location, shape, size, relationship between the neck and the parental artery of the aneurysm and the DSA performance were basically consistent with MSCTA. No false positive results were found. Postoperative examination of MSCTA in 28 cases, all developed well, the arterial artery was well patency, no residual aneurysm was seen. Conclusion: MSCTA can accurately display the location, shape and size of the aneurysm, the relationship between the neck and the artery and the structure of the skull base. It can be used as an important tool for clinical diagnosis and treatment of aneurysm imaging. An important method for post-review and follow-up.
