The ratio of low density muscle (LDM) area to normal density muscle (NDM) area within the Dorsal Muscle Group (DMG) boundary. LDM area is defined as the cross sectional area of the DMG falling in a low density muscle HU range (0 to 30). NDM area is defined as the cross sectional area of the DMG falling in a normal density muscle HU range (31 to 100).
