Advances in Imaging to Assess Response in Rectal Cancer

Summary

The goal of this observational study is to determine the feasibility of acquiring serial MRI images for advanced radiotherapy planning in colorectal patients. The main question it aims to answer: Is it feasible to acquire serial MR images for advanced radiotherapy planning for rectal cancer.
