Potential of dose optimisation in MRI-based PDR brachytherapy of cervix carcinoma.

Background And Purpose: In this study on PDR treatment planning of utero-vaginal carcinoma, we analysed the dosimetry of traditional X-ray based plans as it presents on MR images. The potential gain of MRI-based dose optimisation was assessed.

Patients And Methods: Sixteen patients boosted with PDR brachytherapy after external beam therapy were included.
