NCIt related terms : spiral CT scan; helical computed tomography;

NCIt definition : A method of computed tomography (CT) that uses continuous rotation of the X-ray tube and continuous transport of the patient through the scanning aperture that allows the rapid acquisition of a volume of CT data. Advantages over conventional CT include: rapid acquisition of a large volume of data within a single breath-hold, thus minimizing respiration artifact and misregistration between slices; the ability to reconstruct images retrospectively at any level within the scanned volume; optimization of intravenous contrast enhancement due to the short scan times; improved multi-planar and 3-D reconstruction; and the potential for radiation dose reduction. Same as helical computed tomography. (British Journal of Radiology 1994 May;67(797):436-44);

Alternative definition : NCI-GLOSS: A detailed picture of areas inside the body. The pictures are created by a computer linked to an x-ray machine that scans the body in a spiral path.; CDISC: A method of examining body organs by scanning them with X rays and using a computer to construct a series of cross-sectional scans along a single axis.;
