Assessment of spinal fusion. Critical evaluation of imaging techniques.

Abstract

Before any radiologic imaging modality is employed in an investigation 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 parameters must be optimized before the results of an imaging technique can be compared to other modes of diagnostic evaluation, including surgical observations.
