Does a spinal implant alter dual energy X-ray absorptiometry body composition measurements?

Background Most manufacturer manuals do not verify the use of dual energy X-ray absorptiometry for body composition analysis in subjects with a metal implant. This study aimed to quantify the effects of a spinal implant on body composition, and to determine whether unadjusted lean mass estimates are valid for patients with a spinal implant. Methods A total of 30 healthy subjects were recruited. Three consecutive scans were performed for each...
