Is an MRI scan painful?
An MRI (Magnetic Resonance Imaging) scan is generally painless. This scan does not use X-rays or any other radiation; instead, it relies on strong magnets, radio waves, and a computer to create detailed images of internal body parts. The goal of the scan is to assist doctors in diagnosing conditions affecting soft tissues and monitoring treatment, such as the brain, spinal cord, nerves, muscles, ligaments, tendons, and joints [1].
What do you feel during an MRI scan?
Although the scan itself does not cause pain, there are some sensations you may feel during the procedure:
- Noise: The MRI machine produces loud sounds, such as clicking, humming, and thumping, while taking images. To reduce discomfort, you may be provided with earplugs or headphones [1].
- Staying still: The scan requires you to remain completely still for a period of time to ensure the images are clear [1]. The table you lie on may be hard or cold, and you can request a blanket or cushion to increase your comfort [2].
- Claustrophobia (fear of enclosed spaces): If you suffer from this type of anxiety, you must inform your healthcare provider in advance. You may be given medication to help you relax and reduce anxiety, or your doctor may suggest an open MRI machine, which is less enclosed [1].
How do you prepare for an MRI scan?
Proper preparation can make your experience more comfortable. Here are some important steps:
- Removing metal objects: MRI machines use strong magnets, so metal objects or implants can interfere with the scan and may be unsafe. You will need to remove items such as jewelry, watches, hairpins, and hearing aids [1].
- Informing your healthcare provider: It is essential to inform your doctor if you are pregnant or breastfeeding (especially if you will receive contrast material), if you have kidney problems, or if you have any metal in your body such as bullets or shrapnel, or electronic devices like a pacemaker, artificial joints, or any other implants. Even tattoos or permanent makeup may contain dark ink with metals that can interfere with the scan [1].
- Fasting: In some cases, you may be asked not to eat or drink for 4 to 6 hours before the scan, especially if the scan is for the abdomen [2].
- Hospital clothing: You are usually asked to wear a hospital gown or clothing free of metal zippers or buttons [2].
Contrast Material (Dye)
Sometimes, you may need to receive a contrast material (dye), which is typically given intravenously. This material helps show specific parts of your body more clearly in the images [1]. The most common material is gadolinium, which is very safe. However, you must inform your doctor if you have a history of severe allergic reactions to other medications or if you suffer from kidney problems, as gadolinium can be harmful to people with kidney issues who require dialysis [2].
After the scan
After most MRI scans, you can return to your normal activities immediately [1]. If you were given medication to help you relax, you will need someone to take you home [1]. A radiologist will review the images and share them with your doctor [1].
