Effect of a Novel Procedure for Limiting Motion on Body Composition and Bone Estimates by Dual-Energy X-Ray Absorptiometry in Children

We studied the effect of using the BodyFIX (Medical Intelligence Inc, Schwabmunchen, Germany) to immobilize children during a dual-energy X-ray absorptiometry scan on body composition and bone estimates. Overestimates of soft tissue and bone introduced by the BodyFIX were avoided by using a modified version of the system or were corrected by using mathematical models developed in this study.
