一项由五所大学中心合作开展的研究评估了头部计算机断层扫描（CT）的相对有效性，并与头部平片、放射性核素脑扫描和神经血管造影进行了比较，以检测和诊断脑内肿块。在2，928例患者中，CT增强和非增强是最准确的神经诊断方法，其中1，071例被发现患有颅内肿瘤。血管造影与CT一样准确，而放射性核素研究和平片的准确性要低得多，如果CT和血管造影阴性，很少发现阳性。
A cooperative study by five university centers assessed the relative usefulness of computed tomography (CT) of the head and compared with with plain head radiography, radionuclide brain scanning, and neuroangiography for the detection and diagnosis of masses in the brain. CT with and without contrast enhancement was the most accurate neurodiagnostic method employed in 2,928 patients, 1,071 of whom were found to harbor intracranial tumors. Angiography was as accurate as CT, whereas radionuclide studies and plain radiography were much less accurate and were seldom found to be positive if CT and angiography were negative.
