Figure 4 Standardized mean difference of dynamic contrast-enhanced ultrasound parameters. A: Rise time; B: Fall time; C: Mean transit time local; D: Peak enhancement; E: Wash-in rate; F: Wash-in area under the curve; G: Wash-out area under the curve; H: Wash-in and wash-out area under the curve. mTTL: Mean transit time local; PE: Peak enhancement; HCC: Hepatocellular carcinoma; ICC: Intrahepatic cholangiocarcinoma; SD: Standard deviation; WiR: Wash-in rate; WiAUC: Wash-in area under the curve; WiWoAUC: Wash-in and wash-out area under the curve; WoAUC: Wash-out area under the curve.
