To evaluate the contribution of conventional brain magnetic resonance imaging (MRI) for the determination of intracranial aneurysms.
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.
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.
Aneurysms can also be appreciated on conventional brain MRI, and vascular structures should be reviewed carefully while analyzing brain MRI.
评估传统脑磁共振成像（MRI）在颅内动脉瘤诊断中的作用。
分析45例（29例女性和16例男性；年龄范围32 - 80岁）患有动脉瘤患者的脑MRI和计算机断层血管造影（CTA）。基于动脉瘤的大小和存在情况，对脑MRI和CTA进行比较。通过Bland - Altman图、受试者操作特征曲线和Kappa统计分析来研究MRI和CTA之间的比较。
共评估了57个动脉瘤。CTA上57个动脉瘤中的45%在传统脑MRI上被检测到。在动脉瘤诊断中，CTA与脑MRI之间存在显著相关性（P < 0.05）。在大小测量分析中，CTA与脑MRI之间观察到显著相关性。77%的<4 mm动脉瘤未被检测到，发现MRI检测<4 mm动脉瘤的效率较低。
传统脑MRI也可发现动脉瘤，在分析脑MRI时应仔细查看血管结构。
