I'd just like to clarify: the new machines aren't MRI (the magnets in those would prohibit all metal objects being within 100ft).
The new machines are also xray; but the xray emiters and detector are now on a spinning carriage similar to an MRI. This allows you to build a 3d model of the object and calculate it's volume, which when combined with the density measurements gives much more reliable material detection.
This also means your stuff doesn't have to be removed from bags to ensure items aren't blocking each other from the scanner.
You're so right, it makes perfect sense. Thanks for the correction!
