Patterns of enhancement of liver lesions with traditional extravascular contrast agents, Multihance and Eovist are reviewed. A comparison between enhancement patterns of these agents on the arterial and portovenous phase are reviewed for different liver lesions. The strengths and limitations of each contrast agent are discussed 

Diagnosis of liver lesions on MR is based on spatial and temporal patterns of enhancement seen with extravascular gadolinium based contrast agents that on delayed images move into the extracellular space. Newer contrast agents with excretion into hepatocytes have arterial, portovenous and equilibrium phase enhancement  that maybe different from traditional gadolinium based agents. These differences should be recognized and incorporated into diagnostic decision making and are reviewed. In addition technical optimization of MR scans for each agent is discussed, strenths and limitations are reviewed

Liver contrast agents are discussed their relative strengths and limitations are reviewed. Technical optimization of scans for each agent is also reviewed
