MRI reduces variation of contouring for boost clinical target volume in breast cancer patients without surgical clips in the tumour bed

Abstract

Omitting the placement of clips inside tumour bed during breast cancer surgery poses a challenge for delineation of lumpectomy cavity clinical target volume (CTVLC). We aimed to quantify inter-observer variation and accuracy for CT- and MRI-based segmentation of CTVLC in patients without clips.
