MRI Scan of the Neck

What is the exam?

Magnetic resonance imaging (MRI) is a diagnostic imaging technique that uses a powerful magnetic field and radio frequency waves to obtain images of the structures and internal organs of the body. It allows the inside of the body to be observed from any angle and with much greater clarity, providing a large amount of information.

How is it done?

The exam is performed in an area that is protected from external magnetic fields. The patient must not have any type of metal prosthesis or implant, pacemaker, artificial heart valve or any other metal/magnetic object in his or her body.

The patient lies down on the examination table, following the instructions given by a technician. The table then slides into a tunnel located inside the scanner. A magnetic field is generated and radio waves are then emitted, aimed at the organ to be studied. The generated images are captured and stored digitally. Some MRI scans require contrast medium to be administered. This is a substance that allows a distinction to be made between the different anatomical structures (organs and blood vessels). The contrast medium that is ingested is expelled from the body through the urine.
The magnetic field cannot be felt. It is painless. Some people may feel claustrophobic while they are inside the scanner tunnel. If the patient feels cold, he or she can ask for a blanket. The patient receives earplugs because the noise and buzzing sounds are very loud.

Throughout the exam, the patient is observed and monitored by a technician. Excessive movement may distort the magnetic resonance images. If the patient has difficulty keeping still, he or she may receive a sedative. No recovery period is required (unless the patient has been sedated). After an MRI scan, the patient may resume his or her daily activities.
