| pubmed-article:1614318 | pubmed:abstractText | We present an imaging technique that affords direct and noninvasive visualization of brain surface structure. This technique utilizes the signal before the rf pulse in steady-state free precession. This signal highly reflects the spin-spin relaxation time T2 as was studied in our laboratory (Matsui et al. J. Magn. Reson. 62, 12, 1985). Therefore the cerebrospinal fluid (CSF), having a long T2, is depicted as high intensity. The CSF permeates cerebral sulci and fissures. The imaging time with this technique is less than 1 min. | lld:pubmed |
