PURPOSE : To find the method of quantitative evaluation of radiological diagnosis by measuring influences to decision making by referring physicians, and to maximize the efficacy.MATERIALS AND METHODS : Work sheets of 260 questionaires and check lists composed of 10 items each to radiologists and referring physicians were prepared. The work sheets were delivered to 13 hospitals of the National University here in Japan. They were filled out by 10 cases of CT examination and 10 cases of MRI diagnosis at each hospital, and were returned to Osaka University. Every case was consistent through the each of exam order, image diagnosis and decision making. Every case was described by both a radiologist and the physician who ordered the examination and recieved the reports and images.RESULTS : 95% of 260 cases of interpretation of CT and MRI involved both process of the recognition and the thinking. Another 5% were based on genuine intuition. The thinking of physician's side was much more effected by the deeper thinking of radiologists. Pattern of reationship between radiologist's behavior and physician's decision making strongly depends on institutes and modalities.CONCLUSION : Analysis of these 260 cases tells that the level of accomplishment of technical efficacy and diagnostic accuracy on the side of radiology strongly influences the diagnostic thinking by the physician.

目得：通过测量对转诊医师决策的影响，找到定量评价放射学诊断的方法，并最大限度地提高efficiency.MATERIALS和METHODS：工作表的260份问卷和检查表组成的10个项目，每个放射科医生和转诊医师准备。这些工作表被送到了日本国立大学的13家医院。各医院CT检查10例，MRI诊断10例，并返回大坂大学。每例患者在检查顺序、影像学诊断和决策方面均保持一致。结果：260例CT、MRI图像的判读中，95%的病例既有认识过程，又有思考过程。另外5%是基于真实的直觉。医师的思维更受放射科医师的深层思维的影响。放射科医师的行为和医生的决策之间的关系模式强烈地依赖于机构和models.CONCLUSION：这260例分析表明，在放射学方面的技术效率和诊断准确性的完成水平强烈地影响医生的诊断思维。
