HOW IS THIS NOT COMMON KNOWLEDGE???? I've already had my kids and got a vasectomy. It would be so good to have photos like these hanging on the walls for when my boys bring home partners.
Yeah you don't do an MRI without reasons, thats probably why (very safe but less so compared to ultrasound). Also you get the live images with ultrasound I don't think that's standard with those big MRI systems.
There's no danger for an mri unless you've had major surgery involving metal inplants. There's no ionizing radiation so there should be no risks for the fetus.
Cost and scarcity are big limiting factors for mri though. Mri machines are massive permanent installations that cost in the millions. They are already busy with people who need diagnostics of specific conditions. Putting every expectant mother in one would lead to absurd wait times. Whereas doctors offices can have multiple little ultrasound machines on carts that are easy to quickly acquire imagining as part of routine visits.
Exactly. MRI machine is a big, expensive, in-demand thing. Ultrasound is cheap, quick and easy.
Though tbf I think this meme demonstrates that we need to lower the cost of MRIs.
So more dangerous than ultrasound. US is probably the safest thing there is.
There are a couple other dangers (metal particles in the eye, idiots bringing metal things with them...) but also it's not covering the same thing as us. Also more expensive etc etc.
