    Radiologist here. 👋🏻

    You are right it does not require contrast. The scan uses a special technique to reduce signal from tissue that isn’t moving so only things that are moving produce high signal and show up “bright.” Since blood is the only thing really moving in the brain - voila!







  • Not sure why you were downvoted. In some instances I think this may absolutely be a factor and the generational perpetuation of such an environment is hard to overstate. My spouse and I refer to it as “One Hundred Years of Solitude” after the amazing novel by Gabriel Garcia Marquez. If you haven’t read it, it follows this family in Columbia through multiple generations showing how self-destructive behaviors can be passed through generations in a self-perpetuating way. That’s an aside to say that I agree that yes I suspect that for some folks this is a part of the story.
