    Department of Medical Physics, University of Edinburgh, Western General Hospital, UK
    J Sports Sci 20:563-76. 2002
    ..Although these limitations increase the uncertainties of muscle volume determination by anthropometry, they do not prevent its valid prediction in leaner individuals. The prediction of superficial adipose tissue was poorer...

    Peter Tothill
    Department of Medical Physics, Western General Hospital, Edinburgh, UK Electronic address
    J Clin Densitom 17:91-6. 2014
    ..Uncertainties of around 0.06g/cm(2) are similar to those previously reported for spine scanning and the results from cadaver measurements. They should be considered in assessing the diagnostic accuracy of DXA scanning. ..
