Conclusion
We found that estimation of LBM with a BIA device was easily performed in a clinical setting.
Tailoring contrast dosage to LBM is shown to reduce patient-to-patient enhancement variability,
and may improve vascular and parenchymal enhancement and lesion conspicuity [3-5].
BIA or the Boer formula may yield a more accurate estimate of LBM than the James formula in obese patients [3,
12,
13].
Our study is limited by the small number of patients,
and the lack of a reference standard measurement to which the BIA results could be compared.
There were also few obese patients in which to compare the strengths and weaknesses of the different approaches to LBM estimation.
There are many BIA devices on the marked,
and analyses show that these devices is not uniform in their accuracy [14].
Each device should be investigated before adopting for body composition assessment.
The professional body composition device based on BIA,
shows a strong correlation and can be considered equal to acknowledged formulas (Boer,
James and Hume) for estimating LBM.
This may facilitate optimal contrast medium dosage in clinical practice in the CT-lab since adipose tissue contributes minimally to the distribution volume of contrast medium.
