Abstract
Shortening of interpretation time in computed tomography (CT) colonography is a critical issue in the screening for colon cancer. Recently, the analysis software improvement showed the other images like the dissection and multi-screen views for the shortening of the interpretation time. In this study, we aimed to compare the interpretation methods of CT colonography using the conventional fly-through and multi-screen methods in the same 53 patients. Interpretation time with the multi-screen method was significantly shorter than that with the conventional fly-through method. However, the total interpretation time, including the reporting time, was not significantly different from that of the conventional fly-through method. In addition, we identified a case that was misdiagnosed with the multi-screen method. In conclusion, interpretation of CT colonography with the multi-screen method has the possibility of shortening the interpretation time. On the other hand, training is necessary for the new methods of interpretation of CT colonography. Comparison with the conventional fly-through method is important until expertise is achieved in the interpretation of the new images in CT colonography in the training period.
