CT scan of a Lego toy MRI
Some time ago, I built a Lego MRI system as a giveaway for a pediatric radiologist and had it CT scanned later. So the poor minifig got a double scan ;-)
This is the axial scan shown as cine.
Note that the density of the bricks is different for each color.
In MRI, Lego material would have no signal, of course.
This is a photograph of the lego toy MRI itself:
