What is Cardiac MRI?

Through it, high-resolution images of the different areas of the heart can be obtained in order to accurately assess its function. Magnetic resonance imaging works through the use of magnetic fields and the emission of radio waves, which allows detailed images to be obtained, without being invasive for the patient.

Usually, cardiac MRI is used to assess the size, shape, and function of the heart and thus be able to detect different pathologies such as alterations in the coronary arteries, congenital heart problems or conditions located in some heart muscle.

Recommendations before the study:

Although it is an extremely simple procedure for the patient, it is important that before entering the machine you remember the following: 

  • For a better interpretation of the results and, above all, for your safety, you should remove any metallic object.
  • This procedure does not emit radiation, therefore, you will not have any problems if you use a defibrillator or pacemaker. 

During the study:

The most important thing is that you relax, since it will be necessary for you to remain motionless on the inside of the MRI machine for a period of time that ranges from 20 minutes to an hour at the most.

During a large part of the process, you will hear loud, repetitive sounds, so in some cases, you may choose to use noise-canceling headphones.

Remember that at all times you will be in communication via intercom with a technician, who will give you directions as required by the study.

Once the procedure is completed:

After the procedure, and only in case you have been sedated, it may be necessary to rest and avoid returning to your daily activities that same day. Otherwise, you will be able to resume your routine a few hours after the study.

After interpreting the study data and issuing the corresponding results, your ABC doctor will inform you about the treatment to follow and if any additional studies are required.
