After the scan, you can resume normal activities immediately. But if you have had a sedative, a friend or relative will need to take you home and stay with you for the first 24 hours. It's not safe to drive, operate heavy machinery or drink alcohol for 24 hours after having a sedative.
In patients with normal kidney function, most of the gadolinium contrast medium injected (over 90%) is passed out in the urine within 24 hours.
The side effects patients are reporting now include joint pain, muscle fatigue and cognitive impairment that can last for years. The gadolinium used in the dye is anchored to a molecule to create a nontoxic compound.
If you had intravenous contrast, you should drink at least eight glasses of water throughout the day to help flush the contrast out of your body. Your doctor will receive the results within 48 hours.

Yes, you can eat and drink as normal.
22, a team led by Johns Hopkins scientists suggests that MRI's strong magnet pushes on fluid that circulates in the inner ear's balance center, leading to a feeling of unexpected or unsteady movement.
The contrast medium dye doesn't permanently discolor your internal organs. Instead, it temporarily changes how imaging modalities view and interact with your body. After the completion of your imaging exam, either your body absorbs the contrast material, or you eliminate it through your urine.
Late adverse reactions after intravascular iodinated contrast medium include symptoms such as nausea, vomiting, headache, itching, skin rash, musculoskeletal pain, and fever.
According to the Food and Drug Administration (FDA), the only scientifically established adverse health effect related to gadolinium is a rare condition called nephrogenic systemic fibrosis, or NSF, a painful disease of the skin. NSF can occur in a small subgroup of patients with pre-existing kidney failure.
After being administered, GBCAs are mostly eliminated from the body through the kidneys. However, trace amounts of gadolinium may stay in the body long-term. Recent studies conducted in people and animals have confirmed that gadolinium can remain in the brain, even in individuals with normal kidney function.
If your brain MRI requires a contrast material, your healthcare provider will insert an intravenous catheter (IV line) into a vein in your hand or arm. They'll use this IV to inject the contrast material. Contrast materials are safe intravenous (IV) drugs.
Contrast agents are safe to use during scans, and your body naturally rids you of them within a day or two when you urinate or have a bowel movement.
Drink plenty of water after the MRI scan to help your kidneys flush the contrast out from your body. If you become unwell during the day after your scan, go to your nearest emergency department or general practitioner (GP). The kidneys remove most MRI contrast agents from your blood.
Most people feel nothing after receiving an injection of contrast, Dr. Taouli says. Only a very small number of people will have adverse effects. Of those, a skin rash, hives, and pain at the injection site are more common.
Keep your eyes closed or even wear a blindfold.
It's much easier in an open MRI it's wider than a standard scanner, so patients shouldn't feel any walls touching them.
Labyrinthine stimulation can induce nausea and vomiting. In this case, labyrinthine stimulation by the MRI magnetic field caused vomiting, and the associated increase in intracranial pressure resulted in reopening of a CSF leak.
Background: Magnetic Resonance Imaging (MRI) is associated with high levels of anxiety in many patients which may interfere with image quality and increase examination time.
There are several types of imaging tests that can be used for headache and migraine: An MRI or a CT scan are the most commonly ordered.
If You Have an Overactive Bladder
This feeling of urgency can make it harder to hold urine in. While you may still experience this urgency to a degree, not drinking for several hours before your procedure can make you less likely to experience incontinence during the scan.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
They can talk with you and be there to support you during and after the examination. They can also drive you home if you have sedative medicine during the examination. If you do take sedative medication, you cannot drive yourself.
You shouldn't experience any after-effects from a CT scan and can usually go home soon afterwards. You can eat and drink, go to work and drive as normal. If a contrast was used, you may be advised to wait in the hospital for up to an hour to make sure you don't have a reaction to it.
