Couldn't find anything online except for a reddit thread with random guesses. Alternative explanations are colocating with ER (the places I go to tend to not have an ER so not sure that's the reason), or for CT & Xrays the floors might have to additionally be lead-lined if not on the first floor which adds to the cost (when there's a basement imaging can often be located there apparently). Could also be a convention that's just been established but there's no real reason.
