You will be able to carry on your day as planned once the test has been completed. If you require sedation for the scan, the MRI facility will give clear instructions on what to do before and after the scan. You will not be able to leave until you are fully awake and you will need someone to drive you home.
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.
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.
If you are very claustrophobic, your doctor may give you a mild sedative, or your MRI may be scheduled with sedation. If so you will need to have someone drive you home after the test.
The magnetic fields that change with time create loud knocking noises which may harm hearing if adequate ear protection is not used. They may also cause peripheral muscle or nerve stimulation that may feel like a twitching sensation. The radiofrequency energy used during the MRI scan could lead to heating of the body.
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.
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.
After the exam
Radiology staff will bring you back to your locker and you can change back into your clothes. If injected contrast agent was used, the IV will be removed from your arm before you go home. If you took medication to prevent claustrophobia or were given anesthesia, you must have someone else drive you home.
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.
How long does an MRI scan take? A single scan may take a few seconds or 3 to 8 minutes. You may be asked to hold your breath during short scans. The total scan lasts 15 to 90 minutes, depending on the size of the area being scanned and how many images are needed.
You will not be able to have breakfast the morning of your surgery. You can brush your teeth in the morning, just be sure to spit the water out!
It's important that patients remove all clothing prior to their MRI exam. We ask patients to remove: All outer clothing, including shoes. Bras or any undergarment that could have metal in it.
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. If a contrast material is used, you may feel some coolness when it is put into your IV.
Unless you were given a sedative, you can resume your daily activities! After an MRI, you will be able to walk around, drive, or even go back to work. An MRI is nothing to be nervous about. It will only give a better diagnosis and help your doctors provide the care you need.
After receiving MRI contrast
You should be able to continue with your day as normal. 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).
A brain MRI can take about 30 minutes to an hour to complete. It may take longer if you're getting a brain MRI with contrast. Your healthcare provider will be able to give you a more exact time range based on the specific reason for your scan.
There is no special preparation necessary for the MRI examination. There are no food or drink restrictions prior to the MRI exam. Continue to take any medication prescribed by your doctor unless otherwise directed. MRI or MRA Kidneys, MRCP, Liver or Pelvis: Do not eat anything four hours before the exam.
Eating before your appointment
If you are receiving a certain cardiac MRI examination, you may not have food for two hours before the examination and NO coffee (decaf or regular); NO caffeine; NO tea; and NO chocolate for 24 hours prior to the examination.
Unless you're told otherwise, you can shower and wash your hair the morning of your MRI. Don't use any hair products (such as hair spray or hair gel). Don't wear any metal objects. Remove all jewelry, including body piercings.
What medications are used? Propofol will be given through an I.V. to induce sleep. This medication has a short duration of action and a rapid recovery time and is administered to make sure you remain asleep during the entire MRI study.
What type of anesthesia is used for MRI? Generally, MRIs under anesthesia are performed under sedation, although sometimes they are performed under general anesthesia. Sedation is characterized as being in a state between relaxed and very sleepy, but not quite unconscious.
Why? Because an MRI scanner´s powerful magnetic field... can damage or completely destroy hearing aids, watches, cell phones, PDA´s, storage media, insulin pumps, electronic keys, etc.
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.
The average cost of an MRI can range anywhere from $400 to $12,000, depending on the place of service, health insurance, location, extra medications, the provider, and body part scanned. Health insurance typically covers authorized MRIs.
