Abstract

Abstract: : Purpose:CT and MRI images are essential for the diagnosis of the orbital diseases. But sometimes it is difficult to understand the spatial relationship of the lesions. In this study we tried to evaluate the usefulness of the three-dimensional (3-D) analysis of the orbital diseases with using volume rendering system for CT and MRI. Methods:CT and MRI images were obtained from 10 orbital cases at Kitasato University Hospital from May 2000 through November 2001. Constructing 3-D images using Volume rendering system «VolumeProTM» for those 2-D images, we analyzed normal orbital region, traumatic retrobulbar hemorrhage, and other orbital lesions. Results:3-D images were obtained easily from 2-D images of CT and MRI. Those gave us stereographic image and helped us to understand the lesion anatomically. Conclusion:3-D imaging of the orbital diseases is the useful tool for understanding the intraorbital structures and for diagnosing the orbital masses. This technique is useful not only for understanding the disease and diagnosis, but also the decision making for the treatment, explanation to the patients, and education for the students.
