Hepatobiliary phases in magnetic resonance imaging using liver-specific contrast for focal lesions in clinical practice

Figure 1 Flowchart: Exclusion criteria. MRI: Magnetic resonance imaging; FLL: Focal liver lesions.

Figure 3 Use of hepatobiliary phases: Detection of small metastasis in a potential patient undergoing liver surgery. Computed tomography (CT) (A) and magnetic resonance imaging (B) (10-min hepatobiliary phase) showed metastatic lesion in the right lobe (arrow). However, the doubtful/suspected nodule for metastasis on CT was not confirmed in the hepatobiliary phase (isosignal-white circle, pseudolesion). However, another hyposignal nodule (white arrow) in the left lobe was well evidenced in the hepatobiliary phase (it had not been identified on CT), compatible with secondary involvement.
