    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.









  • Because when looking to replace work horses with a steam engine you didn’t care what the absolute peak output of a horse was. You needed to know how big of an engine you needed based on how large the team of horses already powering the application was. Anyone trying to run a horse anywhere near their peak output for any length of time would injure them.
