Where this comes from

Abstract

Delivery of breath-hold MR-guided SABR is time-consuming, and the use of real-time tumor-tracking in a sagittal plane may fail to detect out-of-plane displacements of organs-at-risk. Analysis of daily MR-scans performed pre- and post-SABR revealed frequent decreases in stomach volumes, and in the planned stomach doses.
