ASSESSMENT OF SPINAL-FUSION - CRITICAL-EVALUATION OF IMAGING TECHNIQUES

Before any radiologic imaging modality is employed in an investigative study, its efficacy must be critically assessed. The purpose of this report is to demonstrate how the choice of computed tomography imaging parameters affects the information provided by a computed tomographic examination. It is apparent from these results that imaging parameter s must be optimized before the results of an imaging technique can be compared to other modes of diagnostic evaluation, including surgical o bservations.
