Magnetic resonance

Ressonància magnètica nuclear a Vall d'Hebron

Nuclear magnetic resonance is a test that allows us to take anatomical, functional images of the human body to diagnose and assess a person's state of health. There are several diseases that require such images, such as trauma, brain and bone marrow explorations and cancer, among others.

Description

How does it work?

 

Using a powerful magnet and radio waves, the magnetic resonance device allows us to get detailed images of the internal structures of the human body.

To have the test done, patients lie down on a stretcher that is inserted into the magnetic resonance device. Usually it lasts between 20 and 40 minutes, during which a nurse or technical staff attend to the patient and indicate what position they need to lie in so that nothing interferes with the images. It is important that patients do not move during the test.

There are times when it is necessary to administer a contrast intravenously, so that some parts of the body can be seen better.

When the patient is a child or does not want to cooperate, professionals can assess whether sedation is necessary.

After finishing the test, the radiologist will interpret the images and draw up the report.
