PDFAbstract
Objective To compare the application value of magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) in the diagnosis of intracranial aneurysms (IAN). Methods The clinical data of 52 patients with IAN confirmed by surgery and pathology in our hospital were retrospectively analyzed. All the patients underwent MRA and DSA after admission. The accuracy of MRA and DSA in the diagnosis of intracranial aneurysms was compared and the diagnostic value was analyzed. Results The detection rate of DSA in aneurysms was 98.21% and of MRA was 94.64% (P>0.05). The differences of MRA and DSA in measuring tumor diameters and neck width were not statistically significant (P>0.05). Conclusion The accuracy rate of MRA is close to that of DSA in diagnosis of intracranial aneurysms and they are noninvasive. They can well display the three-dimensional conformation and shape of aneurysms, which can be taken as the preferred diagnosis of intracranial aneurysms. For patients who can not be diagnosed by MRA, DSA should be adopted for help.
