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

ABSTRACT:

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 participant, one with and two without extraneous spinal implant, without repositioning between scans. Lean, fat and bone estimates in the total body, trunk and limb were measured.

Results

Precision errors for all total and regional body compositions were within the recommended ranges. Bone masses in the trunk and total body were s
