Diagnostic imaging is meant to reduce that uncertainty, ideally to the point where a clinician feels confident enough to choose a course of action. But the process of diagnostic imaging is itself prone to high variability and error. Sources of variability include technical, procedural, and anatomic variation, the variable use of language to describe and report radiological abnormalities, and the range of variability in the manifestations of disease processes Cognitive biases and varying understanding of the prevalence and likelihood of disease among radiologists can also lead to interpretive error. This chapter explores the sources of error and the sources of uncertainty in the radiological process. There is considerable overlap between the two.","PeriodicalId":262101,"journal":{"name":"Error and Uncertainty in Diagnostic Radiology","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123289485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The amazing properties of human visual perception have been found to involve a (perhaps unexpectedly) complex interplay between the eye and brain and can be affected by a large number of factors in surprising and unexpected ways. We will discuss what is different about a radiologist’s brain in this regard, compared to the brains of people who are not similarly trained and experienced. The chapter reviews the most common radiologist errors, as these may yield key insights into the process and lead to more effective strategies for error prevention.","PeriodicalId":262101,"journal":{"name":"Error and Uncertainty in Diagnostic Radiology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130908277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We will review the relative contribution of perceptual error—in which findings are simply not seen—as compared to other common types of error. This error epidemiology will be considered in the light of the underlying variability and uncertainties present in the radiological process. The role of key cognitive biases will also be reviewed, including anchoring bias, confirmation bias, and availability bias. The role of attentional focus, working memory, and problems caused by fatigue and interruption will also be explored. Finally, the problem of radiologist error will be considered in the context of the overall problem of diagnostic error in medicine.","PeriodicalId":262101,"journal":{"name":"Error and Uncertainty in Diagnostic Radiology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114731534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
