Liver-stiffness measurements under free breathing are lower than those under apnea.

Stiffness discrepancies might be due to elevated central venous pressure during apnea.

Quality indexes of free breathing SWE image were generally poorer than that of apnea.

Under unfavorable clinical conditions free breathing SWE measurement is not reliable.
