A member asked:
Can mri contrast give you a headache? as had an mri today with contrast and felt sick and had a headache afterwards. it was mri of the heart.

Yes,: uncommonly a transient headache and/or nausea can occur following injection of an MRI contrast agent. It is important to note that this is not an allergic reaction, but rather due to the effect of the contrast on receptors in the brain. If you need to have contrast in the future, it may or may not recur.
