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.
虽然在大脑和小脑中,灰质和白质可通过计算机断层扫描(CT)区分,但中脑部分的分辨率尚未见报道。对中脑的CT图像和解剖切片进行比较,以确定小脑上脚(白质)、红核和中央灰质的相对密度。正常情况下,小脑上脚的低衰减不应被误解为梗死或脱髓鞘。
