Whole-Body MR Angiography
Whole-body MR angiography is the ideal method to depict all arteries of the body three-dimensionally. This is how we can search for vascular abnormalities on all levels of your body. This technology allows us to make assessments about the most important blood vessels of all parts of the body:
- head and neck vessels
- vessels in your torso
- peripheral vessels
In many cases, MR angiography replaces an angiographic examination using a catheter and X-rays.
Process of the Examination
You are lying on a moveable examination table that slowly slides into the tunnel of the machine. Depending on which part of your body is to be examined, you will be positioned in the machine with either your head or your feet in the front. The examination lasts 20 minutes to about one hour depending on the part of the body to be examined and the desired results. During this time, you should lie on your back as calm and relaxed as possible.
During the examination, you are holding an emergency buzzer which you can push if needed. Depending on the examination, an ECG device is put on your chest in order to interpret the results in unison with your heartbeat. Moreover, surface coils are laid on you and loosely fixed in place by straps. Since the MRI machine produces loud knocking sounds, you are given sound-proof headphones with which you can listen to music if you wish. It may also be necessary for you to follow commands on how to breathe during the examination.
The objectives of some examinations necessitate the use of a contrast agent which is injected via an arm vein at a certain point in time during the examination. To this end, a so-called "indwelling cannula" is inserted into your arm and attached to the pump of the contrast agent in the examination room. The contrast agent employed in the MRI scan does not contain iodine but rather gadolinium which is generally well tolerated by the body. Very seldom do patients have an allergic reaction, e.g. itching, skin rash, nausea. Excretion of the contrast agent ensues via the kidneys. Please tell us if you suffer from a kidney disorder.
Please observe these absolute contraindications if you have:
- a pacemaker
- an implanted neurostimulator
- a cochlear implant or any other electronic implants
In case of doubt, we kindly ask you to contact us before your examination.
