OBS! Participate physical in Arvid Carlsson lecture Hall at Academicum or online through zoom. No registration required.
Welcome to the Sahlgrenska Academy Science Seminars, a series of seminars on Thursdays at 15-16. The seminars are, from November 2021, conducted both physical in Arvid Carlsson lecture hall at Academicum and online through zoom.
Here is the link to the webinar: https://gu-se.zoom.us/j/63483925988
The seminars are open to anyone interested in taking part of scientific breakthroughs and projects in the medicine and health science field. Scientists, students and other staff from GU, VGR and other organisations with the common interest of medicine and health science, welcome!
Speaker: Emilia Palmér, Dep. Of Clinical sciences, GU
Topic: MRI – A much needed development for cancer treatment
A common approach to treat cancer is to use radiation with high energy photons, and about half of all cancer patient receives radiation therapy (RT) at some point during their treatment. To plan for an effective treatment with as few side effects as possible, imaging data that illustrate a distinct and exact position of tumour and organs at risk must be available. The traditional RT workflow uses computed tomography (CT) to define tumour and organs at risk. The CT provides information necessary to calculate the delivered radiation dose but has the disadvantage of low soft tissue contrast. An imaging modality that does provide high contract between different type of soft tissues is magnetic resonance (MR) imaging, and this modality are therefore of great value in the modern RT workflow. But, considering the major role of magnetic resonance (MR) in medicine in general today, the use of MR in RT is still highly limited, mainly due to the many special requirements that needs to be fulfilled to use MR in RT. The latest modernization of the RT workflow is to completely exclude CT from the planning process, and instead convert information from the MRI to the information necessary to calculate the delivered dose leading to a so-called MRI-only RT workflow. This seminar will talk about the challenges of using MR in radiation therapy. It will describe Sahlgrenska University Hospital´s journey from 2014 when the RT dedicated MR was installed until today when it is a natural part of the RT workflow, and the ongoing research in the field.
