  • * For these subjects, tissue swaps occurred in all repeated scans. Values in parentheses are extracted from 1 scan each for which tissue swaps were corrected manually. This was done by inverting ST and fat values in MR-AC maps in respective regions. This is predictive for LBM with no tissue swaps but is not supposed to result in same LBM gained from artifact-free MR-AC image.

  • LBMMR-AC column shows values of LBM gained for all acquisitions with and without tissue swap and missing tissue artifacts. Scaled LBMMR-AC column shows values scaled by scaling factor gained from linear regression.
