Yellow stool after cat scan test

I had a Cat Scan yesterday.  I had to drink barium prior to the test and they also injected me with contrast dye.  This morning my stools were bright yellow.  I called the place where I had my cat scan and she said she's never heard of that happening before.  I called my dr. but he's not in today.  Is this normal?  I'm kind of concerned that my liver couldn't handle all that stuff they put in me.  I was also having stomach pain above my belly button last night.

Thanks for any info you can provide.
