Bias and the expert witness in radiological malpractice litigation Rationale Misdiagnosis of disease in a medical image is likely due to search, perception or cognition errors. An additional contributing factor is the poor quality of clinical information given to the radiologist by the referrer. In certain malpractice cases, the radiologist (defen...

Rationale and objectives: To measure the effect of visual hindsight bias on radiologists' perception during chest radiograph pulmonary nodule detection. Materials and methods: This was a prospective multi-observer study to assess the effect of hindsight bias on radiologists' perception. Sixteen radiologists were asked to interpret 15 postero-ant...

This experiment investigated whether there might be an effect on the visual search strategy of radiologists during image interpretation of the same adult chest radiographs when given different clinical information. Each of 17 experienced radiologists was asked to interpret a set of 57 (10 abnormal) posteroanterior chest images to identify the prese...
Article
Rationale and Objectives: The aim of this study was to measure the effect of prevalence expectation as determined by clinical history on the diagnostic performance of radiologists during pulmonary nodule detection on adult chest radiographs. Materials and Methods: A multi-observer, counter-balanced study (having half the readers in each group read...
Article
Full-text available
Rationale and objectives: This research investigates whether an expectation of abnormality and prior knowledge might potentially influence the decision-making of radiologists, and discusses the implications for radiological expert witness testimony. Materials and methods: This study was a web-based perception experiment. A total of 12 board-cert...

This study aims to determine whether receiver operating characteristic (ROC) scores inferred from free-response receiver operating characteristic (FROC) were equivalent to conventional ROC scores for the same readers and cases. Forty-five examining radiologists of the American Board of Radiology independently reviewed 47 PA chest radiographs under...

Aim: To measure the effect of thinking aloud on perceptual accuracy and visual search behavior during chest radiograph interpretation for pulmonary nodules. Background: Thinking Aloud (TA) is an empirical research method used by researchers in cognitive psychology and behavioural analysis. In this pilot study we wanted to examine whether TA had an...

Questions

Question (1)
Question
In a case where a radiologist misses a lung cancer the only information he might have at the time is "patient has cough". Once the cancer is diagnosed and said patient sues the radiologist for negligence, does the patient's expert radiologist have more information when reviewing the original image? If so, surely there is hindsight bias which should deem the evidence unreliable.
