Some people have mild nausea, cramping, or diarrhoea from the contrast material injected ingested. This will usually pass after an hour or two.
What happens after the MRI scan? You are likely to have diarrhoea after the scan and therefore, you will need to stay close to a toilet for the rest of the day. We recommend that you arrange for someone to drive you home because of the effects of any medication we may give you for your scan.
You may be advised to wait half an hour to see if you react to the contrast solution or buscopan. As the contrast solution can cause diarrhoea, you are strongly advised to go to the toilet as much as you can before you leave the hospital. It can also cause diarrhoea and cramps for a few days.
An even smaller number (between about 1 and 4 in 100) will notice mild nausea or headache. Vomiting can occur, but this is rare (less than 1 in 100 injections). Gadolinium contrast medium is generally very safe. Side effects or reactions are uncommon, but can occur.
Second degree burns are the most commonly reported patient problem. Other reported problems include injuries from projectile events (objects being drawn toward the MRI scanner), crushed and pinched fingers from the patient table, patient falls, and hearing loss or a ringing in the ear (tinnitus).
Some MRI scans involve having an injection of contrast agent (dye). This makes certain tissues and blood vessels show up more clearly and in greater detail. Sometimes the contrast agent can cause side effects, such as: feeling or being sick.
If you are given contrast by mouth, you may have diarrhea or constipation after the scan. Otherwise, you don't need any special care after a CT scan of the abdomen. You may go back to your usual diet and activities unless your healthcare provider tells you differently.
Flu-like symptoms. Headache. Metallic taste. Nausea, vomiting or diarrhea.
Some patients feel a small amount of discomfort from bloating or cramping during the exam. Please arrive at the MRI Department 15 minutes before your scheduled exam.
If you are suffering from gastrointestinal issues, many different imaging tests can be beneficial in diagnosing diseases of the digestive system. Standard imaging tests for gastric conditions include MRIs, CT scans, and ultrasound.
Other rare but possible delayed reactions include nausea, vomiting, diarrhoea or constipation, abdominal pain, pain in the injected arm, rash, dizziness and headache. These signs and symptoms almost always disappear within a few hours and usually little or no treatment is required.
Common side effects of contrast materials are generally mild and may include a rash, nausea, and vomiting. More severe reactions can include anaphylactic shock or nephrogenic systemic fibrosis.
On very rare occasions, a few patients experience side effects from the contrast material. These may include nausea, headache, and pain at the site of injection. It is very rare that patients experience hives, itchy eyes, or other allergic reactions to the contrast material.
The kidneys remove most MRI contrast agents from your blood. People with normal kidney function pass the contrast out into the urine between two to 24 hours after it is injected.
You won't have pain from the magnetic field or radio waves used for the MRI test. But you may be tired or sore from lying in one position for a long time.
Delayed reactions can occur 1 hour to 7 days after exposure, are often mild, and include flu-like symptoms, nausea, diarrhea, rash, pruritus, urticaria, abdominal pain, and dizziness; these tend to occur more with ionic contrast agents.
Because radiation is not used, there is no risk of exposure to radiation during an MRI procedure.
If you have to go to the bathroom, then go to the bathroom. On the other hand, do not go to the bathroom unless you must. There is a chance that you may be asked to drink some contrast material before the scan. You do not want this contrast material to mistakenly leave your body because you went to the bathroom.
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.
The most common adverse reactions are minimal: headache, nausea (feeling slightly sick) and dizziness for a brief time after the injection. A few patients will have a feeling of coldness at the injection site.
Late adverse reactions after intravascular iodinated contrast medium include symptoms such as nausea, vomiting, headache, itching, skin rash, musculoskeletal pain, and fever.
Temporary side effects – The iodine-based contrast dye used in a PET CT scan can cause temporary side effects. Some PET scan side effects are diarrhea, nausea, etc., which eventually fade within a day.
How long after receiving contrast could I have an allergic reaction? A small number of people have a reaction to contrast more than 1 day after they receive contrast. Most people who get these delayed reactions have rashes, itchy skin, headaches, or nausea.
Mild hypersensitivity reactions (incidence <3%) consist of immediate skin rashes, flushing or urticaria pruritus, rhinorrhea, nausea, brief retching, and/or vomiting, diaphoresis, coughing and dizziness; moderate to severe (incidence <0.04%) reactions include persistent vomiting, diffuse urticaria, headache, facial ...
