High-pitch spiral CT: effect on image quality and radiation dose in pediatric chest CT

posted by Michael M. Lell, M.D. | Oct 26, 2017
Michael M. Lell, M.D.

Computed tomography (CT) is considered the method of choice in thoracic imaging for a variety of indications. Sedation is usually necessary to enable CT and to avoid deterioration of image quality because of patient movement in small children. We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the … Read more
