Figure 2. Example case of a LR-M nodule. 78-year-old male with HBV and a growing nodule on MRI, approximately 3 cm, previously diagnosed as a hemangioma on MRI. CEUS imaging demonstrated arterial phase hyperenhancement at 16 s followed by almost immediate washout by 34 s. Biopsy showed the mass to be intrahepatic cholangiocarcinoma (image reproduced with permission from the ACR). MRI: magnetic resonance imaging; HBV: hepatitis B virus; CEUS: contrast-enhanced ultrasound; ACR: American College of Radiology
