3D Reconstructions for Point-of-Care Computed Tomography

Abstract

Objective: Demonstrate improvements in diagnostic accuracy and efficiencies in health care delivery afforded by the use of 3-dimensional reconstructions of point-of-care computed tomography (CT) in the office of the otolaryngologist.

Method: The Morita Accuitomo 3D CT scanner was used to obtain point-of-care CT images of the sinuses and temporal bones of patients at The Ohio State University Department of Otolaryngology in September of 2010. The advantages and limitations of 3D reconstructions in these cases were documented, and 3D videos were created.

Results: One hundred consecutive cases utilizing 3D CT scans were analyzed for areas of potential improved diagnostic accuracy. Reconstructions increased overall scan time by 35 seconds, on average. Representative cases of typical benefits and disadvantages seen in patients with sinus and ear disease were tabulated. Atypical cases where 3D CT provided unforeseen advantages, including patients with septal perforations and displaced ossicular prostheses, were also identified and analyzed. Three illustrative cases were selected for the creation of 3D videos.

Conclusion: 3D reconstructions of point-of-care CT scans provide enhanced diagnostic accuracy and efficiency of health care delivery, with minimal additional time costs for several patients in this investigation. These findings support the further prospective study of the cost efficiency and potential for improved patient outcomes with this novel technology.
