“…Such discrepancies may have serious clinical implications given that these reports, unlike those of radiology trainees and emergency doctors, are not subsequently checked by a neuroradiologist. Finally, despite the recent interest in cranial CT reporting by neuroradiographers [3], few studies have assessed report discrepancy rates in this group: 1 study assessed 2 radiographers' reports for paediatric head CT and found the accuracy in detecting significant abnormalities to be between 49% and 75% [14]; the only other study has assessed a single radiographer and shown a report sensitivity of 85.4%, which compared favourably with the sensitivity for senior trainees: 87.5% [15]. All these studies have recruited only small numbers of candidates: the maximum number of participants in previous studies assessing head CT reporting has been 18 [8].…”

Objectives: Demand for out-of-hours cranial CT imaging is increasing and some departments have considered addressing this shortfall by allowing non-radiologists to provisionally report imaging studies. The aim of this work was to assess whether it is appropriate for non-radiologists to report head CTs by comparing the misreporting rates of those who regularly report head CTs with two groups of non-radiologists who do not usually report them: neuroradiographers and emergency doctors. Methods: 62 candidates were asked to report 30 head CTs, two-thirds of which were abnormal, and the results were compared by non-parametric statistical analysis. Results: There was no evidence of a difference in the score between neuroradiographers, neuroradiologists and general consultant radiologists. Neuroradiographers scored significantly higher than senior radiology trainees, and the emergency doctors scored least well. Conclusion:The results of this preliminary study show that appropriately trained neuroradiographers are competent at reporting the range of abnormalities assessed with this test and that their misreporting rates are similar to those who already independently report these studies.

Paediatric radiology requires dedicated equipment, specific precautions related to ionising radiation, and specialist knowledge. Developing countries face difficulties in providing adequate imaging services for children. In many African countries, children represent an increasing proportion of the population, and additional challenges follow from extreme living conditions, poverty, lack of parental care, and exposure to tuberculosis, HIV, pneumonia, diarrhoea and violent trauma. Imaging plays a critical role in the treatment of these children, but is expensive and difficult to provide. The World Health Organisation initiatives, of which the World Health Imaging System for Radiography (WHIS-RAD) unit is one result, needs to expand into other areas such as the provision of maintenance servicing. New initiatives by groups such as Rotary and the World Health Imaging Alliance to install WHIS-RAD units in developing countries and provide digital solutions, need support. Paediatric radiologists are needed to offer their services for reporting, consultation and quality assurance for free by way of teleradiology. Societies for paediatric radiology are needed to focus on providing a volunteer teleradiology reporting group, information on child safety for basic imaging, guidelines for investigations specific to the disease spectrum, and solutions for optimising imaging in children.

“…Our training program may also not have been optimal for this specific group of observers. It was developed based on earlier experience by several groups who were successful in training non-radiologists to read imaging studies [5, 11, 21]. We combined both knowledge transfer and hands-on experience in a structured program with direct feedback.…”

“…Previous studies have demonstrated that radiographers can accurately read mammograms [7], plain x-rays [8], intravenous pyelograms [9] and double-contrast barium enemas [10]. Much lower accuracy results have been seen in a study in which non-radiologists evaluated paediatric brain CT but no dedicated training was given in that study [11]. …”

Can radiographers be trained to triage CT colonography for extracolonic findings?

ObjectivesRadiographers have been shown to be capable CT colonography observers. We evaluated whether radiographers can be trained to triage screening CT colonography for extracolonic findings.MethodsEight radiographers participated in a structured training program. They subsequently evaluated extracolonic findings in 280 low-dose CT colonograms (cases). This dataset contained 66 cases with possibly important findings (E3) and 27 cases with probably important findings (E4) [classification based on the highest classified finding (C-RADS)]. The first 40 and last 40 CT colonograms were identical test cases. Immediate feedback was given after each reading, except for test cases. Radiographers triaged cases based on C-RADS classification and indicated the need for a radiologist read. We constructed learning curves for correct case triaging by calculating moving averages.ResultsIn the final test series, 84/120 (70 %) cases with E3 or E4 findings and 139/200 (70 %) without E3 or E4 findings were correctly triaged. Correct identification of cases with E3 findings improved with training from 46/88 (52 %) to 62/88 (70 %) (P < 0.0001) but not for E4 findings [both 22/32 (69 %) P = 1.00].ConclusionsRadiographers improve after training in correctly triaging extracolonic findings at CT colonography but do not reach a high enough accuracy to consider their structural involvement in screening.Key Points• Radiographers were trained to triage CT colonography for extracolonic findings.• After training, radiographers improved sensitivity for likely unimportant findings.• After training, radiographers did not improve sensitivity for possibly important findings.• Radiographers should probably not be expected to identify all extracolonic findings.
