This study measured missed bone diagnosis on CT performed for lymph nodes or visceral spread of cancers and lymphomas. A bone-expert reading was compared to that of visceral-cancer oriented observers. From 100 examinations, 65% of bone abnormalities were not described by current reporting of cancer cases. Changes in windowing and contrast of the image produced large variations in CT readings. A slow search with different windowing decreases the false-negative ratio. A fast reading with invariable viewing parameters increases false interpretations, even for experienced radiologists.
本研究测量了针对癌症和淋巴瘤的淋巴结或内脏扩散进行的CT检查中漏诊的骨病变情况。将骨专家的读片结果与专注于内脏癌的观察者的读片结果进行了比较。在100例检查中，目前癌症病例报告未描述65%的骨异常情况。图像窗宽和对比度的变化导致CT读片结果有很大差异。采用不同窗宽进行缓慢搜索可降低假阴性率。即使对于经验丰富的放射科医生，采用不变的观察参数进行快速读片也会增加错误解读。
