Table 1 Equations for calculating allometric parameters using three different LBM and BSA contrast medium strategies
From: Strategies for calculating contrast media dose for chest CT
Allometric parameters | Equation |
|---|---|
LBM (kg) | |
According to James | |
Female | (1.07 • TBW) − 148 (TBW/H)2 |
Male | (1.10 • TBW) − 128 (TBW/H)2 |
According to Boer | |
Female | (0.252 • TBW) + (0.473 • H) − 48.3 |
Male | (0.407 • TBW) + (0.267 • H) − 19.2 |
According to BIA | |
Female/male | TBW (1–BFP/100) |
BSA (m2) | |
According to Mostellar formula | |
Female/male | [(H • TBW)/3600]0.5 |
