Abstract

Purpose of Review

Imaging is fundamental in the management of colorectal cancer (CRC). Contrast-enhanced computed tomography (CECT) and contrast-enhanced magnetic resonance (CEMR) are the imaging modalities recommended to stage and restage CRC. The aim of this review is to summarize the most relevant studies published on the role of contrast-enhanced imaging for the management of CRC.

Recent Findings

There are published data demonstrating the accuracy of CECT and CEMR for local staging of both colon and rectal cancer, as well as for the evaluation of distant metastases. Moreover, different aspects of these methods, in particular perfusion techniques, are emerging as prognostic biomarkers. The optimization of contrast media injection protocols is essential to ensure reproducibility and high image quality.

Summary

Contrast-enhanced imaging is mandatory in the management of CRC both for the evaluation of the primary tumor and of distant metastases.
