MRI based 3D brachytherapy planning of the cervical cancer - our experiences with the use of the uterovaginal Vienna Ring MR CT applicator
Abstract
Uterovaginal brachytherapy planning is conventionally based on the use of two orthogonal Xray projections. Currently, there is a large development of 3D brachytherapy planning based on the fusion of CT and MRI, which takes into account the extent of the tumor and the location of organs at risk.
In this work, we evaluated the dosimetric data and first clinical results in patients with inoperable cervical cancer using MRI/ CT compatible applicator enabling 3D planning. Between June 2012 and March 2013, we performed 52 uterovaginal applications in 13 patients with inoperable cervical cancer using Vienna Ring MR CT applicator.
Planning was carried out by the fusion of MRI and CT. Target volumes and organs at risk delineation were carried out on the basis of GEC ESTRO and ABS recommendations as well as doses report-ing.
