It is often difficult to see if prostate cancer has spread beyond the prostate gland using standard tests. Fortunately, there is a new imaging test that can help. This test uses a medicine, called a tracer, that binds to prostate cancer cells. It is attached to an emitter that can be detected by PETscanimaging. We can now produce the tracer here in Montreal in a research laboratory in order to support research for patients in Quebec in a way that is more affordable. By having access to this PET imaging tracer, we hope to prove that it is a better way to detect prostate cancer outside the prostate gland. This will help patients in Quebec make better decisions about their treatments and have access to better imaging tests. Here we will test the best way to produce and administer the test such that the results are optimized.
