MRI Scan what is the chalky drink for?

Probably a 'barium meal' – a preparation which contains barium salts. It's not for an MRI but for scanning the stomach and intestines; the barium salts work through the intestines as the preparation is digested, and then show up on radiographic images (x-rays).

The oral contrast used for CT studies is barium sulfate (sometimes flavored with something to make it easier to drink). If this is a CT then I would say it's almost certainly oral contrast that's used to opacify the bowels.

If it's truly an MRI that she's having, it may be gadolinium chelate or manganese-based agent used similarly for oral contrast but I've no experience with this sort of thing.
