  • Visceral Fat Volume With Automated Analysis [ Time Frame: five minutes ] [ Designated as safety issue: No ]
    This is the measurement of Abdominal Visceral Fat in cubic centimeters as determined with a new automated segmentation program.
  • Visceral Fat Volume With Manual Segmentation [ Time Frame: five minutes ] [ Designated as safety issue: No ]
    This is the measure of visceral fat found with our older manual segmentation method

Toward an Automated Method of Abdominal Fat Segmentation of MR Images

Subjects will undergo a brief magnetic resonance (MRI) scan. The resulting images will be used to compare two abdominal fat segmentation techniques. The first technique is already validated and in use. The second technique was recently developed and has not been validated. The hypothesis is that the second technique will be the faster and more reliable of the two.
