Tissue Quantitation Results Printout
You can show tissue quantitation results in the Body Composition section of the
Ancillary results printout. The tissue information combines fat and lean soft tissue.
Other tissue data in the report combines soft tissue and bone tissue.
Tissue quantitation gives the information that follows:
• R-Value of regions with sufficient soft tissue—this value gives the ratio of
38-keV attenuation to 70-keV attenuation in soft tissue. A typical R-Value is
1.28 thru 1.38. A higher value shows a leaner patient.
• Fat as a percentage soft tissue only (fat and lean tissue combined) for
each region.
• Fat as a percentage of body mass (soft tissue and bone mass) for each region.
• Total soft tissue content in grams (fat and lean tissue combined).
• Fat tissue content in grams.
