RESUMEN
Objective To investigate the values of320-slice CTA for the diagnosis and intraoperative application ofintracranial small aneurysms.Metbods Fifty patients with pathologically confirmed intracranial small aneurysms were selected as the study subjects from January 2012 to June 2016.All the patients underwent 320-slice CT examination,and then the diagnostic values of 320-slice CT were discussed.Results Totally 48 patients were confirmed with intracranial small aneurysms and the diagnostic accordance rate was 96％,and there was missed diagnosis in 2 patients and no patients mis-diagnosed.The results by 320-slice CTA were mostly consistent with those by pathological examination.320-slice CTA displayed the site,shape,size,aneurysm neck height and adjacent structure of intracranial small aneurysms clearly in 49 patients,and undeveloped aneurysms due to narrow entrance or intraluminal thrombosis occurred in 1 patient.Conclusion 320-slice CTA gains advantages in diagnosing intracranial small aneurysms such as non invasion and high convenience and provides basis for clinical treatment,and thus is worthy promoting clinically.
