Improved detection of cortical and subcortical tubers in tuberous sclerosis by fluid-attenuated inversion recovery MRI.
We carried out fluid-attenuated inversion recovery (FLAIR) pulse sequences with long repetition and echo times in seven children with tuberous sclerosis, and compared them with conventional spin-echo (SE) sequences. FLAIR images exhibited higher sensitivity than conventional SE images to cortical and subcortical tubers. The low signal intensity of cerebrospinal fluid on FLAIR images allowed more accurate delineation of the cortical and subcortical tubers. However, T1-weighted imaging was still superior for delineation of subependymal nodules.
