“…We found this to be a common feature, seen in 35 (81%) of the renal cancers: 25 cancers deformed the outer contour, 6 protruded into the renal sinus and displaced the renal sinus fat, and 4 altered the contour of most or all the kidney. Using multiplanar images can help recognize a renal contour abnormality (17). …”

“…As these prior studies utilized preselected cohorts of renal cancers, they cannot be used to determine the detection rate of renal cancer in clinical practice. Evaluation of patients brought to case review conferences or otherwise identified on an ad hoc basis has demonstrated errors in detecting non-stone renal pathology at unenhanced CT (16,17). However, the renal cancer detection rate cannot be determined with these study designs.…”

“…Horton et al have also examined misdiagnoses in CT reports of the abdomen and recommend the regular use of alternative windows to increase lesion conspicuity and use of multiplanar and/or three-dimensional reconstructions. 20 In contrast to CT, only 28 cases of discrepancy on MRI were referred. This may be due to two factors: first, that MRI was outsourced to another off-site provider until November 2007; and second, all the MRI scans are double read.…”

Common patterns in 558 diagnostic radiology errors

Introduction: As a Quality Improvement initiative our department has held regular discrepancy meetings since 2003. We performed a retrospective analysis of the cases presented and identified the most common pattern of error. Methods: A total of 558 cases were referred for discussion over 92 months, and errors were classified as perceptual or interpretative. The most common patterns of error for each imaging modality were analysed, and the misses were scored by consensus as subtle or non-subtle. Results: Of 558 diagnostic errors, 447 (80%) were perceptual and 111 (20%) were interpretative errors. Plain radiography and computed tomography (CT) scans were the most frequent imaging modalities accounting for 246 (44%) and 241 (43%) of the total number of errors, respectively. In the plain radiography group 120 (49%) of the errors occurred in chest X-ray reports with perceptual miss of a lung nodule occurring in 40% of this subgroup. In the axial and appendicular skeleton missed fractures occurred most frequently, and metastatic bone disease was overlooked in 12 of 50 plain X-rays of the pelvis or spine. The majority of errors within the CT group were in reports of body scans with the commonest perceptual errors identified including 16 missed significant bone lesions, 14 cases of thromboembolic disease and 14 gastrointestinal tumours. Of the 558 errors, 312 (56%) were considered subtle and 246 (44%) non-subtle. Conclusion: Diagnostic errors are not uncommon and are most frequently perceptual in nature. Identification of the most common patterns of error has the potential to improve the quality of reporting by improving the search behaviour of radiologists.

“…As the importance of abdominopelvic CT (APCT) scans increases, radiologists are faced with the challenge of ensuring comprehensive and accurate imaging interpretations. 1 It has been shown that multiplanar reformatted (MPR) images in multidetector row CT can improve the diagnostic performance, resulting in a more accurate image interpretation compared with axial images alone. 1 However, our experience is that abdominal radiologists are still predisposed to diagnostic errors in the interpretation of routine APCT imaging, despite these advances in imaging technology.…”

Diagnostic errors when interpreting abdominopelvic computed tomography: a pictorial review

Diagnostic errors remain an inevitable occurrence during abdominopelvic CT (APCT) interpretation, despite advances in imaging technology. The main cause of error is failure to identify a lesion (i.e. perceptual error) and failure to recognize a finding's significance (i.e. interpretive or cognitive error). Awareness and understanding of the causes of errors can reduce their occurrence and may lead to a reduction in morbidity and mortality. This pictorial essay highlights various causes of error in interpreting APCT scans and briefly discusses possible solutions for minimizing these errors.
