Impact of Real-Time Three-Dimensional Rendering of CT Data on Diagnostic Performance
Helical acquisition of computed tomography (CT) data enables the complete coverage of larger anatomic regions. Secondary reconstructions in additional planes out of these data volumes are therefore of better quality than reconstructions from sequentially acquired axial slices. The usefulness of such reconstructed images has been proved in several prospective and retrospective studies, particularly for planning surgical interventions and for evaluating post-traumatic alterations or in certain expansive diseases [1, 3, 4, 12, 13, 16, 19]. However, all these studies compared only the added value of data postprocessing and did not consider the diagnostic effectiveness of the reconstructed images by using them instead of those acquired in the axial plane.
