What kind of injection is given for a MRI?
If your exam does require the use of the injection, a small needle is inserted into a vein in your arm. We let some normal saline drip into the vein first. This is to keep access open to the vein during the MRI exam. About two-thirds of the way through the exam, we will inject a contrast agent called “gadolinium.” This material is only used for MRI. You may feel a cool sensation going up your arm. As with anything taken into your body, there is a very slight chance of an allergic reaction.
