MRI is much lower resolution than X-ray. Dental researchers are speculating about using MRI for some uses, like implant planning, but the laws of physics are not in favor of reducing the voxel size to match the small features identified with X-rays.
My dentist just upgraded their gear, the tech no longer leaves the room when shooting the image, and I didn't get a lead blanket. Presumably that means the technology improved again and the total X-ray energy went down.
- derefr 5y agoI don't know much about MRI technology, but would you get an improvement in resolution if the whole machine was scaled down (i.e. because it only needs to fit someone's head in it, rather than their whole body)?
- Kliment 5y agoThere's already head-only MRI machines. Like all MRI machines, they are phenomenally expensive to operate, eat shittons of energy, and only make sense if they're in constant use. But yes, reducing bore size improves resolution.
