The effect that accompanying patient information has on diagnostic accuracy in radiologic interpretation has been studied by many researchers but remains a matter of contention. Experiments in the past emphasized the chest film because this procedure is the one done most frequently in radiology. However, with the increasing importance of digital imaging, the role of patient history in these procedures should be assessed. The use of a model computerized patient history in the interpretation of digitized chest images that were displayed on a high-resolution workstation was studied. Two hundred forty-seven selected posteroanterior chest images that indicated disease and that indicated no disease were interpreted in random sequence by five board-certified radiologists, with and without accompanying patient histories. Readers were prompted by the response forms to evaluate images for the possible occurrence of interstitial diseases, nodules, or pneumothorax. No significant differences (P = .05) in the detection of these abnormalities were noted between case readings with and without history for any of the radiologists or for the group as a whole. However, this methodology reflects a direct interpretation approach. The results of this study may not necessarily be applicable to individual prompts, different imaging procedures, or other abnormalities.
许多研究人员对伴随患者信息对放射学解读诊断准确性的影响进行了研究，但这仍是一个有争议的问题。过去的实验重点关注胸片，因为该检查是放射学中最常进行的操作。然而，随着数字成像的重要性日益增加，应评估患者病史在这些检查中的作用。本研究探讨了在高分辨率工作站上显示的数字化胸部图像解读中使用模型化计算机患者病史的情况。5名获得委员会认证的放射科医生对247张选定的显示疾病和未显示疾病的后前位胸部图像进行随机顺序解读，解读时分别有无伴随患者病史。应答表格提示阅片者评估图像中是否可能存在间质性疾病、结节或气胸。对于任何一位放射科医生或整个小组而言，在有病史和无病史的病例解读中，这些异常的检出率均无显著差异（P = 0.05）。然而，这种方法反映的是一种直接解读方式。本研究结果不一定适用于个别提示、不同的成像检查或其他异常情况。
