A 57-year-old female with metastatic neuroendocrine tumor to the liver, the mediastinum, and lung (a). Hepatobiliary phase imaging of the liver demonstrates multiple hypointensities (b, arrows) that correlate with DOTA-TOC uptake on respiratory compensated PET imaging (c). By combining the navigated HBP imaging and respiratory compensated PET data, accurate fusion between PET and MRI can be performed (d)
