Flowchart of the study population.

Clinical impact of the Gadoxetic acid-enhanced liver MRI on the management plan of the patients with liver metastasis of colorectal cancer.

A 51-year-old woman with sigmoid colon cancer, who showed liver metastasis only on Gadoxetic acid-enhanced liver MRI. (a) Axial ¹⁸F-FDG-PET/CT image shows inhomogeneous physiologic activity of liver but no definite metastatic nodule. (b) Axial image of hepatocyte-phase on liver MRI shows a focal signal defect in segment 2 suggesting metastatic nodule (arrow).

A 46-year-old man with sigmoid colon cancer, who showed one metastatic nodule on PET/CT and two metastatic nodules on liver MRI in both hepatic lobes. (a) Axial ¹⁸F-FDG-PET/CT image shows a focal increased uptake in left lateral section of the liver (curved arrow), but there is no definite FDG uptake in right hepatic lobe. (b) Axial image of hepatocyte-phase on liver MRI shows focal signal defects in left lateral section of the liver (curved arrow), and also in the subcapsular portion of right hepatic lobe (arrow), suggesting two metastatic nodules in both hepatic lobes.
