The CT machine noise should be apparent from the OP, but just to make it clear: You're hearing the giant motor that spins that thing around several times per second.
The MRI machine is a bit different. The noises it makes are literally the machine itself creaking in different ways to the different types of varying magnetic fields it uses to scan you.
@atatassault @ivor @qotca @stux โCreakingโ doesnโt really do it justice IMHO ๐. A wooden ship under sail โcreaksโ, or an old rocking chair. An MRI machine is more akin to sticking your head inside a large church bell and someone hitting it with a hammer
