      AIM: To determine the accuracy of radiographers red dot or triage of accident and emergency (A&E) radiographs in clinical practice. MATERIALS AND METHODS Eligible studies assessed radiographers red dot or triage of A&E radiographs in clinical practice compared with a reference standard and provided accuracy data to construct 2×2 tables. Data were extracted on study eligibility and characteristics, quality, and accuracy. Pooled sensitivities and specificities and chi-square tests of heterogeneity were calculated. RESULT Three red dot and five triage studies were eligible for inclusion. Radiographers' red dot of A&E radiographs in clinical practice compared with a reference standard is 0.87 [95% confidence interval (CI) 0.85¿0.89] and 0.92 (0.91¿0.93) sensitivity and specificity, respectively. Radiographers' triage of A&E radiographs of the skeleton is 0.90 (0.89¿0.92) and 0.94 (0.93¿0.94) sensitivity and specificity, respectively; and for chest and abdomen is 0.78 (0.74¿0.82) and 0.91 (0.88¿0.93). Radiographers' red dot of skeletal A&E radiographs without training is 0.71 (0.62¿0.79) and 0.96 (0.93¿0.97) sensitivity and specificity, respectively; and with training is 0.81 (0.72¿0.87) and 0.95 (0.93¿0.97). Pooled sensitivity and specificity for radiographers without training for the triage of skeletal A&E radiographs is 0.89 (0.88¿0.91) and 0.93 (0.92¿0.94); and with training is 0.91 (0.88¿0.94) and 0.95 (0.93¿0.96). CONCLUSION Radiographers red dot or triage of A&E radiographs in clinical practice is affected by body area, but not by training.
    • Letter re: Comparison of acetabular and femoral morphologies on hip, pelvic, and lumbar radiographs (Yun et al.)

      Snaith, Beverly; Flintham, K. (2018)
      We read with interest the recent article by Yun et al. [1] comparing acetabular and hip measurements across pelvis, hip and lumbar spine radiographs. The authors assert that lumbar radiographs can be utilised in place of routine pelvis radiographs for these measurements. The example lumbar spine radiograph (figure 2) appears to be an abdominal image, with a contrast urogram. Indeed, standard texts [2,3] confirm that the anteroposterior lumbar spine radiograph should not include any coverage of the hips as appropriate collimation should limit the anatomy to T12 superiorly, lower sacrum inferiorly and the sacroiliac joints laterally, which would exclude the hip joints. Thus assessing any hip measurements on an appropriately collimated lumbar spine radiograph should not be possible. This is further compounded by the description of the centring point within their study (iliac crest), which varies from the internationally recognised standard of lower costal margin/L3 [2,3].
