Comparative Interpretation of CT and Standard Radiography of the Chest

Abstract

With modern multislice computed tomography (CT) scanners, which combine ultrafast acquisition with high spatial resolution, isotropic imaging of the chest can be performed during a short breathold. Adapting the slice thickness, the reconstruction increment, filter, and matrix enable an optimal isotropic visualization of each organ. The very large high-quality 3-dimensional datasets that are then generated require the use of various postprocessing techniques for an improved diagnostic. These tools have become a vital component for the visualization and the interpretation of the large volumetric data and to present the results to the clinicians. New dynamic modes of visualization have recently been introduced to reduce the storage capacity and to improve the workflow and the image quality for any organ interpreted by the user. Despite this gain in information obtained with modern multislice CT scanners, the patient’s dose has not been increased. On the contrary, it has been reduced thanks to the use of automatic dose modulation which adapts the X-ray tube output to maintain adequate dose and image quality when moving to different body regions.
