The informative value of conventional x-ray film and computed tomography was analysed on the basis of findings in 214 patients having 9 primary and 189 secondary malignant tumours as well as 16 benign bone tumours. In 44% of the benign bone tumours CT yielded decisive additional information in so far as it became possible to determine the type of tumour (4) or the paraosseous tumour extension (3), respectively. The tumour status of the primary malignant tumours was determined throughout via x-ray film, whereas intraosseous and extraosseous extension of the tumorous process was covered much better by computed tomography. CT did not yield additional information in 28% of the secondary malignant bone tumours, whereas 33% of the osseous destructions--depending on the size and localisation--could be identified only via computed tomography. Decisive additional information was gained via CT in 39% of the patients mainly in respect of intraspinal or endocranial tumour extension.
基于214例患者的检查结果，分析了传统X线片和计算机断层扫描（CT）的信息价值。这些患者中有9例原发性恶性肿瘤、189例继发性恶性肿瘤以及16例良性骨肿瘤。在44%的良性骨肿瘤中，CT提供了决定性的额外信息，因为据此分别有可能确定肿瘤类型（4例）或骨旁肿瘤扩展情况（3例）。原发性恶性肿瘤的肿瘤状态通过X线片整体得以确定，而肿瘤进程的骨内和骨外扩展情况通过CT能更好地显示。CT在28%的继发性恶性骨肿瘤中未提供额外信息，而33%的骨质破坏——取决于大小和位置——只能通过CT识别。在39%的患者中，通过CT获得了决定性的额外信息，主要涉及脊髓内或颅内肿瘤扩展情况。
