There is a need to develop imaging methods that can assess treatment response and help individualise therapy in patients with oesophageal cancer. We explore the utility of dynamic contrast-enhanced MRI in a pilot study of 5 patients with oesophageal cancer. Each patient underwent two 3D DCE-MRI scans, each separated by a course of radical chemo radiotherapy. All patients showed significant treatment response demonstrated by changes in post-treatment pharmacokinetic parameters. We have successfully applied 3D DCE-MRI in oesophageal cancer and demonstrated its potential to assess treatment response.
