title:
PET/MRI enabled theranostic digital twins for personalised precision radiotherapy for brain
metastases and tumour (PET-DT)
Summary:
Brain tumours (BT) kill more children and adults under the age of 40 than any other cancer. 50+% BT are brain
metastases (BM). BT have poor prognosis and directly impact severely neurologic function, psychological
health and quality of life. Standard treatment for BM and BT comprises surgical resection, radiotherapy (RT) or
surgery with RT. The effectiveness of a treatment is evaluated through radiomics (feature-based or deep
learning-based from CT, MRI, or PET images) as a standard. However, the treatment response depends not
only on size but also on the structure of metastases which may contain tumour cells and tissue compartments
of contradicting radio-sensitivity. Hence the current ‘one-size-fits-all’ paradigm where the same amount of
therapeutic activity per cycle is administered lacks consideration of individual characteristics and features as
well as inter-variability in radiation biology and immunological factors, leading to substandard treatment
outcomes.
This PET-DT interdisciplinary researcher-exchange project aims to develop novel computational techniques using digital
twin (DT) technology to achieve personalised precision radiotherapy planning and prediction for brain tumour
and metastases treatment. The emerging hybrid imaging technique of Positron Emission Tomography/Magnetic
Resonance Imaging (PET/MRI) will be employed to simulate and analyse quantitatively the metabolic functional
data and physiological information.
