.........At the London Regional Cancer Program, Drs. Fisher, Lock, and Bauman are overseeing two observational trials looking at liver and brain cancer patients undergoing radiation therapy. Enrolled patients are receiving a blood flow imaging (CT Perfusion) scan before and after their radiation treatment course. These images are analyzed, to see how regions with different blood flow characteristics respond to radiation. The goal is to collect enough data to be able to predict the optimal amount of radiation needed to treat each region of the tumour. Our understanding of radiation through blood flow imaging would better allow us to produce a tailored radiation therapy plan unique to each patient's tumour using the pre-treatment blood flow images 

 Dr. Ting-Yim Lee, a scientist at the Robarts Research Institute and St. Joseph's Health Care London, has developed a medical imaging technique called computed tomography perfusion (CT Perfusion). This technique allows for the measurement on a millimetre scale of blood flowing in tissue.(full story)
