3D fast recovery fast spin echo MRI for contouring in cervix cancer brachytherapy

At our department, T2w fast spin echo (FSE) MRI is used for contouring, while 3D T2w fast recovery fast spin echo (FRFSE) MRI is co-registered with FSE images for applicator reconstruction. We aimed to assess the value of FRFSE MRI for High risk CTV (HR CTV) contouring.

Gynecologic radiation therapy : novel approaches to image-guidance and management

3D MR and CT imaging is basis of modern brachytherapy. In this chapter recommended imaging techniques for both modalities are described, including the relevant physical background. Contents of this chapter can help the reader to establish modern 3D imaging for brachytherapy.

Inter-observer comparison of target delineation for MRI-assisted cervical cancer brachytherapy : application of the GYN GEC-ESTRO recommendations.

With the application of image-guided brachytherapy (IGBT) the dose conformity increases, but the method still depends on the ability of the radiation oncologist to delineate to a high degree of accuracy the target structures. The results of this study show that the application of the GYN GEC-ESTRO recommendations for IGBT contouring at two different institutions (Institut Gustave Roussy and Medical University of Vienna) with two different traditions for applicators, CTV assessment, MR image acquisition and dose prescription is feasible, and produces acceptable inter-observer variability.

Inter- and intraobserver variation in HR-CTV contouring : transverse and paratransverse image orientation in MRI assisted cervix cancer brachytherapy

Brachytherapy MRI based treatment planning can be employed succesfully only if the important issues of inter- and intraobserver contouring variability and MR image orientation are thoroughly investigated. Our results show that contouring in paratransverse (PT), as compared to transverse (T) plane, facilitates a comprehensive understanding of spatial relations between the applicator and the patho-anatomical structures. HR-CTV delineation in PT, as compared to T orientation is marked by a similar contouring time, is reproducible and leads to a comparable outcome in terms of DVH parameters.

Adaptive contouring of the tagret volume and organs at risk

Brachytherapy has developed exceptionally during last years, particularly in the field of image guidance. Therefore, the need for a review monograph, describing modern principles of brachytherapy, arised in the community. In this chapter principles of 3D image-based contouring of target and organs at risk for gynecologic brachytherapy has been described.
