The value of group consultation in improving the accuracy of radiologic diagnosis was assessed. Abnormalities on 24 films were pointed out to six groups of three radiologists each. They were asked to reach a specific diagnosis for each case. Accuracy was compared in three settingss: (1) without consultation; (2) with consultation leading to a diagnosis by group consensus; and (3) with consultation followed by independent diagnoses. The accuracy of over 75% of the radiologist improved after consultation in either setting. The extent of improvement was inversely related to the initial accuracy level of the individual. When two or three radiologists agreed initially, they were more frequently correct than not. Group discussion followed by individual diagnosis is a practical approach to radiologic consultation.
评估了小组会诊在提高放射学诊断准确性方面的价值。向六组放射科医生（每组三人）指出了24张胶片上的异常情况。要求他们对每个病例做出明确诊断。在三种情况下比较了准确性：（1）无会诊；（2）会诊后通过小组共识得出诊断；（3）会诊后进行独立诊断。在任何一种情况下，超过75%的放射科医生会诊后的准确性都有所提高。提高的程度与个体最初的准确性水平呈负相关。当最初有两三位放射科医生意见一致时，他们的判断更常是正确的。先进行小组讨论然后进行个体诊断是放射学会诊的一种实用方法。
