Image-Guided Radiotherapy and Chemotherapy in Gynaecological Cancer

MRI: cylinder

➢ Largest variation cranial and lateral in ‘folds’ and ligament structures

➢ Pathology study shows that 95% of lymph vessels are located in superficial 3 mm of vaginal tissue.

Consensus for study: • Cylinder 3 mm ‘ring’ expansion, where necessary further expansion • Include ‘vaginal folds’ to document dose in folds • Exclude: ligament structures cranially; air, fluid
