Course Material 


This exercise consists of participants reading a short clinical vignette about the pre-selected post-operative spine case. Then, they will review the relevant investigations – including operative notes and pre- + post-operative imaging, before attempting to contour the clinical target volume. Adjacent critical organs may also need to be delineated. (e.g. spinal cord, thecal sac, nerve roots, bowel)

During the webinar, the session will start off with sub-speciality experts (surgeon, radiologist, radiation oncologist) giving a short talk on the relevant aspects of clinical management.
This will be followed by a break-out practicum session where participants can compare their interpretation of CTV with other group members, and against the suggested CTV by the expert.

Lastly, we will end the session with the radiation oncologist running through his CTV contour and explaining why he did, or did not, include certain areas. This is be followed by an overall panel discussion with the invited experts.


This program is designed to meet the interest of radiation oncologists and radiation oncology residents.


Each of the workshop sessions will last for two hours.  The session will cover the following areas:

  • (Pre-course) Access to platform and hands-on contouring by participants

  • Short talks each by sub-site surgeon, radiation oncologist and radiologist

  • Presentation of the case and delineation guidelines used

  • Breakout session to review participants’ contours in comparison to the reference contours

  • Summary of key points by expert panel 

  • Discussion between participants and experts

Learning Objectives

  • To be familiar with indications, types of surgeries, types of implants for spinal mets

  • To appreciate the various imaging modalities used in spine mets imaging, both in the de novo and post op setting. To be familiar with the types of artefacts seen with spinal implants and strategies to mitigate these

  • To be able to identify residual tumors and expected post-operative changes

  • To be able to define the high-risk CTV for post-op spine SBRT

  • To be aware of the common pitfalls in delineation
