New MR techniques for the detection of liver metastases
Abstract
It is well established that hepatic resection improves the
long-term prognosis of many patients with liver metastases.
However, incomplete resection does not prolong survival, so
knowledge of the exact extent of intra-hepatic disease is
crucially important in determining patient management and
outcome. MR imaging is well recognised as one of the most
sensitive methods for detecting metastases. Recent developments
in gradient coil design, the use of body phased array coils and
the availability of novel MR contrast agents have resulted in MR
being recognised as the pre-operative standard in this group of
patients. However, diagnostic efficacy is extremely dependent on
the choice and optimisation of pulse sequences and the
appropriate use of MR contrast agents. This article reviews
current MR imaging techniques for the detection and
characterisation of metastases and discusses the relative
capability of different techniques for detecting small lesions.
