MRIs would be another revolutionized field. Cooling is a big size constraint and cost driver. You would still need a large amount of power if you want to have clinical scans at 3T or 5T, though, but in wealthy countries the number of MRI machines would for sure proliferate and it would probably become more routine. Low-resource environment deployments may become a tad more feasible, to be honest the power requirements will still probably be too high, but at least you wouldn't need an always-on source.
