What does it consist of?
You must be stretched on your back with your head resting on a cushion, the table will move to the area to study that is in the center of the resonance equipment. The test can last from 30 to 45 minutes, during this time, you will have to remain as calm as possible, since the taking of images is not continuous but different image planes are made. Subsequently, with this information, we proceed to reconstruct the images that will allow us to visualize the lymphatic vessels. Once finished, you will be able to continue with your daily life as normal.
In this test it is necessary to administer subcutaneous contrast and then proceed to the opacification of the lymphatics of the punctured area, being more intense to greater drainage of them.
CASES IN WHICH IT IS RECOMMENDED
Who is it for?
- Identify the sentinel lymph node or the first lymph node to receive lymphatic drainage from a tumor.
- Plan a biopsy or surgery that will help evaluate the stage of the cancer and create a treatment plan.
- Identify blockage points in the lymphatic system, such as lymphatic flow in an arm or leg or lymphedema.
How should you prepare?

- Metal objects: The technician will give you the necessary instructions, provide you with a gown and ask you to remove any metal objects (jewelry, watch, piercings, hairpins, mobiles, dental prostheses and hearing aids).
- Heart devices: It’s important to tell the technician about any devices you’re implanted in your body (pacemakers, electrodes, and clips from previous surgeries).
