Abstract

We performed a study to determine whether clinical history gives a positive or negative influence on X-ray film interpretation. One hundred and nine patient's radiograms, consisting of 55 normal and 54 abnormal cases (136 abnormalities), were interpreted twice by three pairs of residents in radiology and a pair of qualified radiologists, without clinical history first and with clinical history next. The interpreters recorded diagnosis and confidence level of normal or abnormal findings on a six-point scale. Analysis of receiver operating characteristic (ROC) curves showed that knowledge of clinical history improved diagnostic accuracy. Residents, especially beginners, should be advised to obtain clinical history whenever they read radiograms.

摘要

我们进行了一项研究，以确定临床病史对X光片解读有积极还是消极影响。109例患者的X光片，包括55例正常病例和54例异常病例（共136处异常），由三对放射科住院医师和一对合格的放射科医生先后两次进行解读，第一次不参考临床病史，第二次参考临床病史。解读人员以六点量表记录正常或异常发现的诊断及置信度。受试者工作特征（ROC）曲线分析表明，临床病史知识提高了诊断准确性。应建议住院医师，尤其是初学者，在阅读X光片时获取临床病史。
