Abdominal CT-based Muscle/Fat Segmentation AI Solution
PROS® CT: MQ
Segments and analyzes the muscle and fact of the extracted L3 slice
*Source: Performance report, based on Dice Coefficient Score
A fat index strongly correlated with metabolic state
A new index that provides more detailed muscle-related information
Classified into I and II based on the extent of fatty infiltration
*Hounsfield Unit(HU)
Type 2 diabetes mellitus¹
“Higher VFA and VSR at baseline were independent risk factors for the development of T2DM.”
NAFLD (non-alcoholic fatty liver disease)²
“A higher proportion of good quality muscle was associated with lower risks of NAFLD and fibrosis.”
Sarcopenia³
“BMI-adjusted index(SMA/BMI) was the best index of CT-measured SMA to reflect the age-related muscle changes and to maximize the diagnostic yield for sarcopenia.”
Myosteatosis⁴
“The NAMA/TAMA index developed in this study was useful for assessing myosteatosis.”
VFA, VSR, LAMA I/II, NAMA/TAMA etc.
