Unit costs of computerized tomography (CT) in Australian hospital practice are considerably lower than those reported in the United States' literature, and not significantly higher than those of nuclear brain scanning which is at a threefold to fourfold disadvantage in false negative rates. CT is cost-effective not only in defining but in screening for neurological disease, and should replace radionuclide scans in both roles.
澳大利亚医院实际使用的计算机断层扫描（CT）的单位成本远低于美国文献中报道的成本，且显著低于核脑扫描的成本，而核脑扫描在假阴性率方面处于三到四倍的劣势。CT不仅在诊断神经系统疾病方面具有成本效益，在筛查方面也具有成本效益，并且在这两个方面都应取代放射性核素扫描。
