Comparative study of DSCT,3.0T MR and DSA in the diagnosis of intracranial aneurysm / 实用放射学杂志

ABSTRACT

Objective To evaluate the characteristics and clinical application value of Dual Source CT(DSCT),3.0T MR and DSA in the diagnosis of intracranial aneurysm.Methods The imaging characteristics of DSCT,3.0T MR and DSA in 102 patients of in-tracranial aneurysm were analyzed retrospectively.Results The cerebral DSA were performed in 102 patients,and the sensitivity and accuracy of DSA were 100%.60 patients were detected by DSCT/CTA,and the sensitivity and accuracy of DSCT/CTA were 93.1% and 97.2% respectively.52 patients were detected by 3.0T MR/MRA,and the sensitivity and accuracy of 3.0T MR/MRA were 89.1% and 92.7% respectively.10 patients were detected simultaneously by CT and MR.The diagnostic sensitivity and accu-racy of these three methods had no significant difference(P >0.05).Conclusion The sensitivity and accuracy of DSCT,3.0T MR and DSA in the diagnosis of intracranial aneurysm are high and had no significant difference,each had its characteristic.Reasonable application of the three methods produces higher clinical value.
