Spinal C．T．の経験

Computed Tomography in the Diagnosis of Spinal Disease

Ⅰ．はじめに

　頭部疾患に対するComputed Tomography（コンピューター断層撮影．以下C．T．と略す）の有用性は，既に周知のこととなったが，近年，脊髄疾患におけるspinal C．T．の重要性も認識され始めてきた^{5,7,8,13,14,16）}．われわれは，最近経験したspinal C．T．を供覧し，種々の問題点につき検討を加えた．

Method: During the period from October 1977 through February 1979, 41 cases of spinal diseases were studied by either EMI Whole Body Scanner, CT 5005 or EMI Head Scanner, CT 1010. Slices were 10 min or 13mm thick.

Materials: ① disc diseases 15 cases ② ossification of posterior longitudinal ligament 10 ③ congenital anomalies 5 ④ spinal cord tumors 6 ⑤ trauma 3 ⑥ narrow cervical spinal canal 3 ⑦ calcification of ligamentum flavum 1 ⑧ spinal arteriovenous malformation 1.
