Radiographer reporting has been studied for plain films and for ultrasonography, but not in paediatric brain CT in the emergency setting.
To study the accuracy of radiographer reporting in paediatric brain CT.
We prospectively collected 100 paediatric brain CT examinations. Films were read from hard copies using a prescribed tick sheet. Radiographers with 12 years' and 3 years' experience, respectively, were blinded to the history and were not trained in diagnostic film interpretation. The radiographers' results were compared with those of a consultant radiologist. Three categories were defined: abnormal scans, significant abnormalities and insignificant abnormalities.
Both radiographers had an accuracy of 89.5% in reading a scan correctly as abnormal, and radiographer 1 had a sensitivity of 87.8% and radiographer 2 a sensitivity of 96%. Radiographer 1 had an accuracy in detecting a significant abnormality of 75% and radiographer 2 an accuracy of 48.6%, and the sensitivities for this category were 61.6% and 52.9%, respectively. Results for detecting the insignificant abnormalities were poorer.
Selected radiographers could play an effective screening role, but lacking the sensitivity required for detecting significant abnormality, they could not be the final diagnostician. We recommend that the study be repeated after both radiographers have received formal training in interpretation of paediatric brain CT.
放射技师报告已在普通X线片和超声检查方面得到研究，但在急诊情况下的儿科脑CT检查中尚未开展。
研究放射技师对儿科脑CT报告的准确性。
我们前瞻性收集了100例儿科脑CT检查。使用规定的打勾表格从硬拷贝胶片上读取影像。分别具有12年和3年经验的放射技师对病史不知情，且未接受过诊断性影像解读培训。将放射技师的结果与放射科顾问医生的结果进行比较。定义了三类：异常扫描、显著异常和非显著异常。
两位放射技师正确将扫描读为异常的准确率均为89.5%，放射技师1的敏感度为87.8%，放射技师2的敏感度为96%。放射技师1检测显著异常的准确率为75%，放射技师2为48.6%，该类别的敏感度分别为61.6%和52.9%。检测非显著异常的结果较差。
选定的放射技师可发挥有效的筛查作用，但缺乏检测显著异常所需的敏感度，不能作为最终诊断者。我们建议在两位放射技师均接受儿科脑CT解读的正规培训后重复本研究。
