Standardization of dual‐energy x‐ray visceral adipose tissue measures for comparison across clinical imaging systems
Authors' conclusion
VAT measures can be estimated from GEHC and Hologic scans that classify individuals in a substantially similar way into metabolic risk categories, and systematic bias between the measures can be removed using simple regression equations. These findings allow for DXA VAT measures to be used in complement to other imaging modalities, regardless of whether scans used GEHC or Hologic systems.
