My son had an MRI with gadolinium- turns out he is allergic to it, he developed a full-body itchy rash. There were like 20 interns in to see him, for the experience I guess. They were ready to send him to the ER in case it interfered with his breathing, luckily it didn't.
That would have been frightening. Did it require treatment beyond antihistamine?
I’ve given MR contrast to patients a lot of times (probably tens of thousands) and have seen hives and rashes a handful of times but vastly more often with iodinated contrast in X-ray procedures (usually CT).
