Abstract
The introduction of spiral CT in the early 1990s marked one of the important steps in the evolution of CT-imaging techniques.1,2 The technology allowed clinicians for the first time to acquire volume data without the risk of miss- or double-registration. It also enabled the reconstruction of images at any position along the patient’s length axis as well as reconstructions of overlapping images to improve the longitudinal resolution. Furthermore, spiral acquisition reduced scan times significantly as the patient moved continuously through the gantry rather than step-by-step (step and shoot mode).
