Although computed tomography (CT) delineation of normal white matter of the cerebral hemispheres has been well documented, there has been no description of white matter within the cerebellum. Through the use of phantom studies, CT number correlations between cerebellum and cerebral hemispheres, and anatomic correlation with in vitro specimens, the ability to visualize cerebellar white matter is demonstrated. Thin sections decrease volume averaging and enable consistent imaging of these structures. Size and shape of the corpus medullaris on CT scan may vary with the scan angle and level of section. Representative examples of various normal appearances are illustrated.
尽管计算机断层扫描（CT）对大脑半球正常白质的描绘已有充分记录，但尚未有关于小脑白质的描述。通过体模研究、小脑与大脑半球之间的CT值相关性以及与体外标本的解剖学相关性，证明了可视化小脑白质的能力。薄层扫描可减少容积平均效应，并能对这些结构进行一致的成像。CT扫描上髓体的大小和形状可能随扫描角度和切片水平而变化。文中展示了各种正常表现的代表性实例。
