Changes in target volumes definition by using MRI for prostate bed radiotherapy planning - preliminary results

Abstract

Magnetic resonance imaging (MRI) is used quite routinely in radiotherapy treatment planning in the primary radiotherapy of prostate cancer as it provides more contrast imaging of soft tissues in the small pelvisthan planning CT, thanks to which it allows more exact delineation of target volumes and thus the saving of organs at risk.
