MRI-Based Radiotherapy Planning to Reduce Rectal Dose in Excess of Tolerance

<div>Rectum dose-volume histogram for CT- versus MRI-based planning. The volume of rectum at each dose level in 8 cGy intervals was averaged over 15 trial participants and is shown as a single dose-volume histogram for CT- versus MRI-based radiotherapy plans. Hatched area shows volume reduction of expected clinical benefit.</div>
