Multidetector CT is used to be the most common imaging technology in the evaluation of colorectal liver metastases. The heightened soft-tissue resolution provided by magnetic resonance (MR) imaging makes it a potential problem-solving tool in the assessment of colorectal liver metastases
particularly with the introduction of new imaging technologies
such as diffusion weighted imaging (DWI)
hepatocyte-specific contrast-enhanced MR imaging
dynamic contrast-enhanced MRI (DCE-MRI)
and so on. In this paper
their basic principles
main function parameters
and applications in the evaluation of colorectal liver metastases are reviewed.
