From Sixteen Slices to Nowadays — Cardiothoracic Imaging with CTthe development and ongoing refinement of CT-imaging techniques. The first generation of MDCT systems offered simultaneous acquisition of four slices at a shortest gantry rotation time of 0.5 s and provided considerable improvement of scan speed and longitudinal (.-axis) resolution and better utiliz

Cardiac Gatingconstruction techniques to virtually freeze the cardiac motion and to avoid motion artifacts in the images. Scan and image reconstruction needs to be synchronized with the heart motion, e.g., by using information from the patient’s electro-cardiogram (ECG) that is recorded in parallel to the CT scan

Cardiothoracic Image Postprocessingnwanted information that distracts from the clinical findings. The basis for image postprocessing is a three-dimensional image volume, which in most cases consists of a stack of individual axial images. The fundamental three-dimensional unit in this volume is called a “voxel.” Ideally, the spatial r

Dose Reduction in Chest CT image the entire chest in 2–5 s, producing up to 1,000 slices, each composed of sub-millimeter isometric voxels. These high signal-to-noise ratio, large field-of-view images provide non-invasive anatomic evaluation of the chest with similar information content to that achievable at autopsy. In vivo

Physiological Interactions opened the field of functional evaluation. However, interactions between heart and lung have long been identified as important physiological phenomena in pathology (.). For the radiologist, they are involved in difficulties of interpretation in a MDCT thorax examination and in the understanding of
