Figure 4From: Effects of patient factors on noninvasive liver stiffness measurement using acoustic radiation force impulse elastography in patients with chronic hepatitis C Receiver operating characteristic (ROC) curves to classify the METAVIR fibrosis stages. Two diagnostic modalities, liver shear wave velocity (SWV), and FibroTest (F score) were compared. P value: significance for comparisons of areas under ROC curves between using liver SWV and FibroTest.Back to article page
