Why is there a poster about Dopamine in the X-ray Room?
I mean, Dopamine is a neurotransmitter and thus cannot be detected with x-rays, not that x-rays are used with high frequency on the brain. There are other scans for that.
Blame the fact Neuro is currently all about the Dopamine for me noticing this fact
Current Mood: curious
I was about to say that when diagnosing Alzheimer's or other brain diseases you're measuring the number of dopamin receptors in the brain. But for that you'd need a PET scanner... I think that's a different machine, I'm not too sure though [/geek mode]
It's definitely a different machine used for PET scanning. It picks up the radiation from the radiated substance introduced into the blood, and requires rather different detection methods.
I know, I know, I just wondered if it was because of that, I can really think of no other reason. There are ventures to build one machine which functions as both, but I have no idea if hospitals can buy those already
I suppose one could argue that since both deal with radiation, maybe the room is multipurpose. Or something.
Technically NMR is not using radiation, just magnetic fields. Sorry, I am still too proud of that A in the exam to let this go ;)
I could see why they would want one machine for it, IIRC you usually do both anyway (as PET only gives you these nice blobs of colour), and it would be a lot cheaper to just buy one machine for two purposes

Art director had a blank spot on the wall that needed dressing.
I speak as a former set designer: it don't have to make sense, it gotta look good.

Re: poster about Dopamine in the X-ray Room
Yeah, that's probably the most logical explanation. ;)
I just picked up on it because of the last three weeks of lectures on Dopamine.
I wondered if it was set-dressing to capture Martha's feeling of "omg, this man is CRAZY INNA HED"
I don't think it'd be intended that way, because Dopamine isn't quite that well known. But it's an interesting subtext to consider.
