PURPOSE: To evaluate whether adding a contrast-enhanced fluid-attenuated inversion recovery (FLAIR) sequence to routine magnetic resonance imaging (MRI) can detect additional abnormalities in the brains of symptomatic @entity1 with mild @entity131 . MATERIALS AND METHODS: Fifty-four @entity1 with persistent symptoms following mild @entity6075 were included in our retrospective study (M     F = 32     22, mean age: 59.8    16.4, age range: 26-84 years). All MRI examinations were obtained within 14 days after @entity542 (mean: 3.2    4.1 days, range: 0.2-14 days). Two neuroradiologists recorded (1) the presence of traumatic @entity75 on MR images with and without contrast-enhanced FLAIR images and (2) the pattern and location of meningeal enhancement depicted on contrast-enhanced FLAIR images. The number of additional traumatic @entity75 diagnosed with contrast-enhanced FLAIR was recorded. Correlations between meningeal enhancement and clinical findings were also evaluated. RESULTS: Traumatic @entity75 were detected on routine image sequences in 25 @entity1 . Three additional cases of @entity75 were detected with the contrast-enhanced FLAIR images. Meningeal enhancement was identified on contrast-enhanced FLAIR images in 9 cases while the other routine image sequences showed no findings of @entity131 . Overall, the additional contrast-enhanced FLAIR images revealed more extensive abnormalities than routine imaging in 37 cases (p<0.001). In multivariate logistic regression analysis, subdural @entity1410 and @entity909 showed a significant association with meningeal enhancement on contrast-enhanced FLAIR images, with odds ratios 13.068 (95% confidence interval 2.037 to 83.852), and 15.487 (95% confidence interval 2.545 to 94.228), respectively. CONCLUSION: Meningeal enhancement on contrast-enhanced FLAIR images can help detect traumatic @entity75 as well as additional abnormalities not identified on routine unenhanced MRI. Therefore contrast-enhanced FLAIR MR imaging is recommended when a contrast MR study is indicated in a @entity1 with a symptomatic prior closed mild @entity542 .
