You use those images of slices (a couple thousand) to reconstruct the fetus in 3D, which is pretty cool and much better than ultrasound.

MRI images are usually 256x256xY or 512x512xY.

yeas, but about 2000 of those AFAIK, more depending on the machine

The slice number is the Y part, and it's usually lower than the previous numbers (usually 40-120). MRI voxels are anisotropic. You get multiple slices per scan, but only one image, so the 2000s of 3d images doesn't make sense.

Of course "depending on the machine" is tricky, cause 8T MRIs exist (and I think they've gone above 10T by now). And the more powerful you get the more resolution you can crank in. But those MRIs are not available for standard hospitals (those are around 3T) and I have no experience with images produced from such machines.
