Elasticity parameter Definition
E shear wave elasticity
E mean_trans mean shear wave elasticity measured along the transverse orientation
E mean_long mean shear wave elasticity measured along the longitudinal orientation
E max_trans maximum shear wave elasticity measured along the transverse orientation
E max_long maximum shear wave elasticity measured along the longitudinal orientation
E sd standard deviation of the shear wave elasticity for each region of interest
E sd_trans Esd measured along the transverse orientation
E sd_long Esd measured along the longitudinal orientation
E mean_ratio Emean_long/Emean_trans
E sd_ratio Esd_long/Esd_trans
f mass 1000 Vmin/d
f mass_trans fmass along the transverse orientation
f mass_long fmass along the longitudinal orientation

Vmin is the minimum shear wave speed (m/s); d is the greatest dimension of the nodule measured from the B-mode images.
