Placement of a region of interest (A) around a metastasis in a 33 year-old female patient with squamous cell carcinoma of the nasal sinus. As the lesion is located subcapsular, the peripheral zones (dotted and dashed circles) are placed excentrically around the lesion ROI (continuous circle), under careful avoidance of larger vessels, other focal lesions or extrahepatic structures. Additionally, a T2-weighted (B), an arterial phase (C), and the hepatobiliary phase (D) images are given.
