Computed tomography colonography (CTC) is the primary radiological examination for detection of colorectal cancer and premalignant polyps. It is a complex technique that requires special training and experience of both the radiographers performing the colonography and the radiologists who interpret the results. The considerable number of CTC performed means that interpretation of the examinations is a time-consuming task for radiologists. Therefore, this study aimed to evaluate the diagnostic performance of radiographers who received a training programme in colon diagnosing.
During the period from December 2014 to May 2015, 126 patients underwent CTC screening or diagnostics. The colon was interpreted by both a radiographer and an experienced radiologist. Subsequently, results were compared and consensus established.
A total of 100 patients were included, six polyps (6-9 mm), one polyp (≥ 10 mm), four cancer suspect areas and four second opinions. The result was nine true positives, three false positives, no false negatives and 84 true negatives corresponding to a negative predictive value of 1.000 and an accuracy of 0.969.
This study shows that radiographers can be a valuable contribution in the interpretation of CTC.

计算机断层扫描结肠成像（CTC）是检测结直肠癌和癌前息肉的主要影像学检查方法。它是一项复杂的技术，需要进行结肠成像的放射技师以及解读结果的放射科医生都具备特殊的培训和经验。大量的CTC检查意味着对这些检查结果的解读对放射科医生来说是一项耗时的任务。因此，本研究旨在评估接受结肠诊断培训计划的放射技师的诊断性能。
在2014年12月至2015年5月期间，126例患者接受了CTC筛查或诊断。由一名放射技师和一名经验丰富的放射科医生对结肠进行解读。随后，比较结果并达成共识。
共纳入100例患者，发现6个息肉（6 - 9毫米）、1个息肉（≥10毫米）、4个癌症疑似区域以及4个二次诊断意见。结果为9例假阳性、3例假阴性、无假阴性以及84例真阴性，阴性预测值为1.000，准确率为0.969。
本研究表明，放射技师在CTC解读方面可以做出有价值的贡献。
