A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
How long does something need to stay still for a CT scan and can you send water through, just thinking about aquatic animals if you could just send the tank through.
Looking at my axolotl who can happily sit there not moving for hours in the hope of ambushing prey, staying still should be easy enough.
On OkCupid, I once briefly courted a woman with the username "RazeTheAxolotl." One of my opening questions was whether she meant "raise" or "raze." She meant "raise."
I don't think asking that helped with my chances. We didn't end up going on any dates.
I don't think animals are ever okay getting CT scanned
tomorrow is monday again, folks
20 ccs of lasagna, stat!
This made me smile! I love it 😀

Interesting.
Did you take these pictures, or could you mention their source? I want to make sure the author(s) get credit.
The author is my mom
I have a feeling, most of those are MRT and not CT
MRT machines are much larger than the devices shown here.
This feels like the equivalent of getting abducted by a superintelligent alien race, being put into a machine beyond your wildest comprehension, and then probably getting a treat and sent back home where nobody will believe you
The mice got a nice pillow
funny sad fact, if a person weigh 600 or more lbs, they sometimes have to use xrays/ct/mri in the zoos that are meant for larger animals.
This happened in Scrubs.
No shit, I once had the chance to accompany a patient to an large aninmal hospital for an MRI.
The problem: It was so far away that the patient needed to be airlifted. Which was far beyond the capacity of regular HEMS. So they called in the military and they send a fucking CH-53 cargo helicopter. These things are huge and loud. But cool.
That was one interesting ride. Somewhat embarrassing for the patient (who was not in on weight level due to simply eating too much - patient had a massive and life altering orphan hormonal disease) but patient kept somewhat good spirits and the volunteer fire brigade did a good job blocking the view.
Nowadays human medicine has improved - you can now simply use an open MRI with specialised gurneys. They usually can take more than 400kg, sometimes 500kg.
Does a larger MRI produce more data than a smaller one (same data density over a larger volume), or is it the same resolution spread out over a larger space?
It depends. MRI and to an even larger extent CT scans are "targeted" to an area. People are very very rarely scanned "totally".
E.g. you want to look at the cervical spine and therefore only examine this area. While you will also see neighbouring regions these are not necessarily full resolution (only if they can have an impact). So if the imaging run is being done for an area that is not affected much by the fat tissue it won't produce more data necessarily (a cardio MRI is a good example). If you do a abdominal or pelvis MRI/CT is normally does include all tissue and therefore will produce more data.
(Take this with a grain of salt though, while I worked inhospital for a while I am primarily a paramedic and more into repairing vital signs than radiology. While we have mobile CTs nowadays they are brain only and not my area of expertise)
There is an exception for the real complicated cases like the one I mentioned, though. As we didn't want to do the whole transport effort 4 weeks later again because another speciality found another issue the patient was indeed scanned almost completely" (with breaks in-between as that gets uncomfortable fast).
(Sadly enough the whole thing was done 6 weeks later again,indeed, as the patient had suffered from an acute stroke which later killed them. Sad story,really. Never had a chance in life)
Obviously we should have bigger radiology machines. It wouldn’t be unreasonable to have them where you have a substantial fat population.
It would probably be wiser to focus on healthcare access and nutrition than to make extremely expensive and already large pieces of equipment triple size as standard when alternatives already exist.
And for multiperson scanning of compatible patients in a dramatically more cancerous pandemic-affected modern cohort with dwindling hospital infrastructure! ᕕ(ᐛ)ᕗ
I had a patient tell me he had to go to a zoo for an MRI. I thought it was a self deprecating joke but he was serious.
I’m sorry, but I cannot stop laughing at this hedgehog 😂
I love how it's just taped down with like masking tape lol
Otherwise he’d be moving so fast the blueshift would be visibly noticeable
I hope they checked his pockets before the MRI violently pulls a bunch of rings at dangerous velocities!
MOISTURISE ME
why are they MRI-ing a filet? :3
One of the most difficult parts of veterinary medicine is the fact that your patients can’t directly communicate. Oftentimes, issues go unnoticed simply because the animal masks things like pain. Luckily, the vet immediately knew this hedgehog had something wrong, because it kept exploding into a bunch of golden rings.
