Write these IN YOUR OWN WORDS: The most important assumption to keep in mind when using computed tomography scans for body composition estimation is that a single slice represents whole-body muscle distribution. To minimize error in longitudinal CT measures, the ideal would be to have scans performed using the same scanner by the same technician; this is rarely possible in research or clini- cal settings. From a practical standpoint, it is important that technical information such as tube voltage, scanner type, and slice thickness is documented given that inconsistencies in these variables could affect interpretation. Prospective research using CT, in addition to the aforementioned technical vari- ables, should attempt to control for patient positioning by establishing a standard protocol with the imaging department. Although it may not be feasible, establishing a collaborative relationship with radiologists and medical physicists before attempting to use CT scans to assess body composition is also suggested.
