Computed tomography is widely utilized for the detection and staging of neoplasm. Typical chest, abdomen or pelvis CT scans may produce 10 to 20 transverse slices for each region. The mental reconstruction of the three dimensional anatomy from these transverse sections can be done by a physician who has had training in the analysis and interpretation of cross sectional anatomy and pathology. This mental reconstruction, however, may take years to develop into an efficient tool. With the 3-D reconstructions used in this study, diagnostic information concerning the location, shape and spread of tumor masses can be presented in a simple, intuitive 3-dimensional display. This technique has been found to be useful for improving communication between diagnostic radiologists and consulting physicians.
