Having to look up MRA. It’s just MRI (NMR) but with contrast that goes specifically to the brain (maybe carb-based)?
scan scam

Magnetic Resonance Angiogram. Yeah it’s an MRI. I guess they’re processing it somehow to enhance bloodflow like FMRI. Seems like it doesn’t require contrast.

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!

Is it really an x-ray of the brain? Surely that’s just of the skull.

Technically it’s both. It’s just that the bones stand out much more than the soft squishy insides.

There are brain x-rays called pneumoencephalographs where they replace the cerebrospinal fluid with air, x-ray, and then put the fluid back. Pneumoencephalography and angiography were really the only neuroimaging techniques available for most of the 20th century, so it was pretty common.

I asked mydelf the same. I guess you can only x-ray the brain by itself when it’s not enclosed in the skull? So this should be the best resolution when scanning a living human.

Does the brain belong to Vince McMahon?

Pretty sure a PET scan is when your dog smells your brain for colors

I think of myself a bit like a second Jesus now, honestly. I mean, just look at my works and teachings.
