Figure 5: Receiver operating characteristic (ROC) curve showing the correlation between the presence of ascites and liver shear-wave velocity (SWV; m/sec) (a) or spleen shear-wave velocity (SWV; m/sec) (b) as assessed by acoustic radiation force impulse (ARFI) imaging in patients with liver cirrhosis. The ideal area under the curve is 1.00. The solid lines represent ROC curves based on the liver stiffness (a) and spleen stiffness (b).
