Comparison of Smart-Shear Wave Elastography and Transient Elastography

"1. All Smart-Shear Wave(SSW) imaging examinations will be performed by one operator.~2. The right lobe of the liver is examined through the intercostal view with the patient lying in a supine or semi-decubitus position with the right arm in maximal abduction.~3. Once the optimal sizes of the regions of interest is chosen, they are fixed for subsequent measurement in each subject. Special attention is paid to avoid any focal lesion, vessels, biliary tracts, or artifacts from nearby lung gas or cardiac movement."

"1. Using the M probe in patients with BMI \<30 kg/m2.~2. Liver measurement is taken at either the seventh or eighth intercostal space of each subject over the right lobe of the liver. The measuring depth ranges from 2.5 to 6.5 cm below the skin surface.~3. Examinations are performed by a sonographer blinded to S-shear wave elastography, and biological results."
