Hi Rich,
The contrast used in CT's is an iodine based one. Anyone with iodine allergies can have trouble with it. Usually patients are premedicated with Benedryl but sometimes that doesn't work
They take the pictures while the contrast is going through the veins. It's just a way to more clearly differentiate veins from the surrounding areas.
I would think a reaction to the contrast is far worse than not having it onboard for the scan. Your mom should get a good scan even without contrast
