Our results disclosed that FLAIR images detected significantly more lesions than did fast T2-WI (p < 0.01) and contrast-enhanced T1-weighted images. The FLAIR pulse sequence combined with T2-weighting with nulling of the signal from cerebrospinal fluid was superior to fast spin-echo sequences in detecting peripheral and periventricular lesions. Post-contrast-enhanced T1-weighted images were more suitable for detecting leptomeningeal processes than were FLAIR images. We conclude that FLAIR images are complementary to fast T2-weighted images and contrast-enhanced T1W images. We suggest that FLAIR should be part of routine brain MR imaging protocols, particularly to define parenchymal lesions adjacent to the ventricles and sulci. |
