Paul asks Tony how many MRI scans people should be getting.
How often do you think people should get an MRI scan?
Well, certainly people on treatment should be getting an MRI at least once a year and the nice thing with MRI, there’s no radiation, so it’s perfectly safe to do. And the goal of that MRI is twofold. One is to look for any new lesions that could indicate the treatment’s not fully effective and maybe consider switching treatments. And the other goal is for safety. There are some of the treatments that can cause some serious brain infections and by doing an MRI once a year we’re pretty confident we can pick it up before it becomes a major problem and change the treatment.
