computed tomography scanogram

computed tomography scanogram,

a CT technique used especially to measure discrepancies in limb length. CT scout images of the joints of the upper or lower extremity are taken, followed by placement of the CT cursors over the joints to obtain measurements. The CT scanogram is more consistently reproduced and radiation doses are lower than in the conventional imaging technique (orthoroentgenography). See also orthoroentgenography, scanography.
