Magnetic resonance angiography. Prices, reviews, ratings
General information
When exposed to radio waves, electromagnetic energy is released in a fairly strong magnetic field, after which it is recorded and processed using computer.
This study allows you to get high-quality images of blood vessels without the use of radiopaque agents. The procedure is completely painless.
Procedure
Preparation
Before magnetic resonance angiography, the patient is given a questionnaire to fill out, where he indicates whether there are any metal objects in his body (they can affect the quality of the image). Before starting, you must remove absolutely all metal objects, clothing with metal buttons, jewelry, glasses, wigs or dentures. Before the diagnosis, be sure to inform the doctor about any allergies to any drugs.
Magnetic resonance angiography procedure
On a special table, the patient is placed in a magnetic resonance chamber. The doctor leaves the room, but the patient can communicate with him via intercom.
The examination usually consists of 2-6 sessions of obtaining images, each of which lasts from two to fifteen minutes. Depending on the type of diagnostic surgery, the duration is from ten minutes to one hour.
If a contrast study is required, during one of the sessions the patient is given intravenous gadolinium, with the help of which the vessels become more contrasting.
Rehabilitation period
After the examination is completed, the catheter is removed, the puncture site is pressed for 25 minutes to stop the bleeding. A special aseptic pressure bandage is applied to the puncture area and the patient is prescribed bed rest.
