Fig. 5

Example case demonstrating accurate localization of MR and PET data using navigated MRI imaging. Respiratory compensated (RC-liver) PET data (a) demonstrates a lesion in segment 2/4A of the liver, which corresponds with a hepatobiliary phase (HBP) hypointense lesion on MR (b and c). Using a navigated acquisition, the lesion is aligned with the PET data (a and b), as compared to a breath-held acquisition where the lesion is displaced inferiorly with respect to the PET acquisition (a and c)
