title: Can we evaluate cranial aneurysms on conventional brain magnetic resonance imaging?
abstract: OBJECTIVE
  To evaluate the contribution of conventional brain magnetic resonance imaging (MRI) for the determination of intracranial aneurysms.
  
  
  METHODS
  Brain MRI and computed tomography angiography (CTA) of 45 patients (29 women and 16 men; age range, 32-80 years) with aneurysm were analyzed. A comparison was made between brain MRI and CTA based on size and presence of aneurysm. The comparisons between MRI and CTA were investigated through Bland-Altman graphics, receiver operating characteristic curve, and Kappa statistics.
  
  
  RESULTS
  Fifty-seven aneurysms were evaluated. Forty-five percent of 57 aneurysms on CTA were detected on conventional brain MRI. A significant correlation was found between CTA and brain MRI in the diagnosis of aneurysm (P < 0.05). In an analysis of the size measurement, a significant correlation was observed between CTA and brain MRI. Seventy-seven percent of aneurysms <4 mm was not detected and the efficiency of MRI in the detection of aneurysms <4 mm was found to be low.
  
  
  CONCLUSIONS
  Aneurysms can also be appreciated on conventional brain MRI, and vascular structures should be reviewed carefully while analyzing brain MRI.
