Comparison of 3D imaging software on referring to operative findings

There are several types of practicable three-dimensional (3D) image formulation software, including those attached to computed tomography (CT) devices. Based on the images taken by 64-section multi detector-row CT, we formulated three 3D images using 3 different software programs (Advantage Workstation Volume Share4, OsiriX, and CTTRY), and performed surgery with reference to these 3D images in 5 patients. In this study, the characteristics, advantages, disadvantages, and utility in the operative field were compared among the images formulated using each program. Consequently, there were no marked differences in the vessel images at the segmental level, and all software programs were deemed useful. However, there were differences in visualization at the sub-segmental level among the 3 software programs.
