MRI, how do I prepare myself for it?

Magnetic resonance imaging, also known as MRI or magnetic resonance imaging, is a non-invasive diagnostic method used to image internal organs, bones and tissues. Unlike other imaging modalities such as X-rays or computed tomography (CT), MRI uses a strong magnetic field and radio waves to create detailed cross-sectional images of the body.

MRI scanning is particularly useful in diagnosing conditions such as cancer, injuries, inflammation, and neurological disorders such as strokes and Alzheimer's disease. The images produced during an MRI scan can help make accurate diagnoses and plan the best possible treatment.

Preparing for an MRI scan

Before an MRI exam, you should tell the medical staff any relevant information about your health, including any allergies or medical conditions you may have. You should also inform if you are pregnant, have a pacemaker or metal implants, as these may interfere with an MRI scan.

Since MRI is based on magnetism, you should remove any metal objects before undergoing the exam. This may include jewelry, piercings, dentures or even credit cards and keys. You will also be asked to stay away from electronic devices such as cell phones, smartwatches and laptops, as these can interfere with the magnetic field.

During the MRI exam

The MRI exam usually lasts between 30 and 60 minutes and takes place in a specially equipped MRI booth. During the exam, you will lie on a movable table that is inserted into the MRI machine. The medical staff will use a speaker system to inform you of the procedure and give you instructions on how to move and breathe to ensure clear images.

During the exam, you may hear loud tapping sounds produced by the movement of the magnetic fields in the MRI machine. It is important to stay calm and focus on your breathing during the exam to improve image quality.

Potential risks

In general, an MRI scan is safe and non-invasive. However, there are some potential risks associated with the exam. Individuals with metal implants or a pacemaker may be affected by the strong magnetic field and may experience side effects such as dizziness, nausea or headaches. Always inform medical personnel of any potential risks or concerns before undergoing an MRI scan.
