Abstract
Three-dimensional images were generated by reformating data from an axial image set. Separate contours were generated for bone and for tumor. The contour representing the tumor was generated by tracing the tumor using a cursor on the CRT. The contours showed the relationship of the tumor to the skull base. Three-dimensional imaging by this method is more of a communication tool than a diagnostic tool. The information on such images can be derived from close analysis of the axial image set. Indeed, determination of the position of the tumor relative to very precise structures requires analysis of the original images. The three-dimensional imaging does orient the observer and give an overall view of the position of the tumor. Because the contour of the tumor is traced, the final image represents the opinion of the radiologist. Various technical considerations and artifacts are discussed.
