Summary:Subjects undergoing a series of procedures to determine body composition, including dual-energy x-ray absorptiometry (DEXA) scanning and extracellular water volume determination by bromide dilution, demonstrated abnormal DEXA scans in some cases. Oral doses of sodium bromide in the stomach were detected on total body DEXA scanning as contrast material. The physical principles that cause bromide to be imaged in a manner similar to calcium by the DEXA scanner are discussed so that other investigators may be aware of this potential pitfall in body composition analysis.
