MRI is highly sensitive for the detection of both hypervascular and hypovascular liver metastases.  In particular MRI can be performed with Eovist, a contrast agent that is taken up by normal hepatocytes, providing a bright liver background against which small lesions can be detected.

Liver metastases well delineated as dark lesions with Eovist.
Dynamic contrast enhancement shows rapid uptake and washout of contrast from carcinoid metastases to the liver.
