To determine the clinical usefulness of multidetector-row CT for the diagnosis of disorders in cattle, images were obtained from 27 cattle, which were then subjected to postmortem and histopathological examinations. The cattle were divided into three categories of disorder: neurological (18 cases), skeletal (four cases) and other (five cases). In five cattle, which were suspected to have brain diseases, no abnormalities were identified by either CT or histopathological examination. Eight types of lesions were detected by CT in the cattle with neurological and vestibular disorders. The diseases diagnosed included hydrocephalus (three cases), intracranial arachnoid cysts (three cases), otitis media (five cases), cerebral abscess (one case), meningoencephalocele (one case), porencephaly (one case), bicephalus (one case) and rupture of the spinal cord (one case). Lesions were identified in all the cattle with skeletal disorders, including luxation (two cases), fracture (two cases), spondylosis (one case) and congenital disorders of the skeletal system (one case). Morphological disorders in the eyes (one case), nasal cavity (two cases), frontal sinuses (one case), thyroid glands (two cases), lung fields (two cases) and abdominal organs (two cases) were diagnosed by CT.
