Two thousand five hundred and forty computed tomography (CT) examinations over a three year period were studied to determine the number of examinations of the body being performed, the use of body CT by clinicians from different specialties and the proportion of such patients with known or suspected malignant disease. Examinations were divided into head and body categories, the latter being sub-divided into groups on the basis of known neoplastic, suspected neoplastic and non-neoplastic disease. Forty-eight percent of examinations were of the body, and of these 44% were of patients with suspected neoplasia referred by general clinicians. The number of patients with known extracranial neoplasia referred by oncologists or radiotherapists was similar to the number of patients in whom there was no suspicion of malignancy. There is a significant demand for CT in the management of non-malignant conditions as well as in known or suspected malignant disease. The figures provided should be of value to those involved in establishing or updating CT units in general hospitals.
对三年期间的2540例计算机断层扫描（CT）检查进行了研究，以确定身体检查的数量、不同专业临床医生对身体CT的使用情况以及此类已知或疑似恶性疾病患者的比例。检查分为头部和身体类别，后者根据已知肿瘤、疑似肿瘤和非肿瘤疾病分为几组。48%的检查是针对身体的，其中44%是由普通临床医生转诊的疑似肿瘤患者。肿瘤学家或放射治疗师转诊的已知颅外肿瘤患者数量与无恶性肿瘤怀疑的患者数量相似。在非恶性疾病以及已知或疑似恶性疾病的管理中，对CT都有很大需求。所提供的数据对于参与综合医院CT科室建立或更新的人员应具有参考价值。
