RT Journal Article SR Electronic T1 Mesencephalic anatomy: demonstration by computed tomography. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 65 OP 67 VO 2 IS 1 A1 T F Berns A1 D L Daniels A1 A L Williams A1 V M Haughton YR 1981 UL http://www.ajnr.org/content/2/1/65.abstract AB Although gray and white matter are distinguished by computed tomography (CT) in the cerebrum and cerebellum, their resolution in the mesencephalon has not been reported. CT and anatomic sections of the mesencephalon were compared to determine the relative densities of the superior cerebellar peduncles (white matter) and red nuclei and central gray matter. The normal low attenuation of the superior cerebellar peduncle should not be misinterpreted as infarction or demyelination.
