Mr Angiography Neck Test

About The Test

M.R. angiography (M.R.A.) utilizes a strong magnetic field, radio waves, and a computer to assess blood vessels and help detect anomalies. The test does not utilize radiation and could require the injection or injection of contrast materials.

The contrast material used in M.R.A. has a lower risk of triggering reactions to the body than the contrast material used in computed tomography (C.T.).

Discuss with your doctor any health issues such as recent surgeries and allergies and if you are expecting. Magnetic fields are not hazardous. However, they can cause certain medical devices to fail. Most orthopedic implants are not a risk, but it is important to inform the technologist in advance if you are using any device or metals within your body.

Sometimes, your doctor will provide you with a report card containing your implant information. The technologist will need this information. The guidelines for drinking and eating before your examination differ between different facilities.

Unless your doctor advises not to, take your usual medications as you normally do. Take jewelry off at home, and dress in loose, comfortable clothes. If you're afraid of being nearby or are anxious, you might want to ask your doctor to prescribe an infrequent sedative before the examination.

What exactly is M.R. Angiography?

Doctors employ angiography to identify and treat blood vessel-related illnesses. Angiography tests reveal images of blood vessels that are major throughout the body. In certain instances, contrast material is employed.

Doctors perform angiography using:

  • Fluoroscopy ( x-rays) to aid in the placement of catheters within the blood vessel and to inject contrast to see the vessels

  • computed tomography (C.T.)

  • Magnetic resonance imaging (M.R.I.)

For magnetic resonance angiography (M.R.A.), an extremely powerful magnetic field and radiofrequency waves, as well as computers, are utilized to assess blood vessels and assist in identifying irregularities. Like the majority of MR-based tests don't use radiation.

An M.R.A. examination may or may not require contrast material. If required, injection of the gadolinium-based contrast material could be utilized. However, the gadolinium-based contrast material is more likely to cause allergic reactions than the iodinated material employed to perform C.T. angiography.

Therefore, the doctor or technologist typically administers the contrast substance by inserting an intravenous (IV) catheter inside the vein of your arm.

What are the most common applications of this procedure?

Doctors utilize M.R.A. to look at blood vessels in the most important regions, including:

  • Brain

  • neck

  • Heart

  • chest

  • abdomen (such as kidneys and the liver)

  • pelvis

  • feet and legs

  • hands and arms

Doctors make use of M.R.A. to:

  • Detect abnormalities, like aneurysms within the aorta in both the chest and abdomen and other blood vessels.

  • It is possible to detect atherosclerotic (plaque) conditions in the carotid artery in the neck. It can restrict cerebral blood circulation and lead to stroke.

  • Find an arteriovenous abnormality within the brain or in other places.

  • Identify the presence of plaque diseases that have narrowed leg arteries and aid in preparing for angioplasty/stent placement or surgery.

  • Find out if there is a problem in the arteries that lead to the kidneys, observe blood flow to prepare for kidney transplants, or the placement of stents.

  • Help interventional radiologists and surgeons perform repairs to damaged blood vessels, for example, placing Stents or assessing the effectiveness of a stent following its placement.

  • After trauma, find out if there is a problem with one or more arteries in the chest, neck, pelvis, abdomen, or limbs.

  • Examine the arteries that feed the tumor before surgical procedures or other procedures like chemotherapy or selective internal radiation therapy.

  • Recognize the dissection or splits in the aorta of the abdomen or chest or its main branches.

  • Determine the extent and severity of coronary artery disease and its consequences and plan interventions, such as coronary bypass and stenting.

  • Check the pulmonary arteries within the lungs for the presence of pulmonary embolism (blood clots like those coming through the veins of your legs) or A.V.M.s in the pulmonary arteries.

  • Examine congenital defects that affect blood vessels, specifically blood vessels in children (e.g., malformations of the heart or blood vessels caused by a congenital heart condition).

  • Examine the presence of stenosis and blockages of vessels.

  • Check for signs of arterial disease in patients, particularly those with a history of it.

When the iodinated contrast material is not used, M.R.A. can also be used as an alternative to C.T. angiography.

What do I perform M.R.A. done?

This exam is usually performed as an outpatient procedure.

The technologist will put you on the mobile exam table. They might use straps or supports to help you remain still and keep your place.

The technologist can install devices with coils that are capable of sending and receiving radio signals all around or near the body of the body being examined.

M.R.I. tests typically include several runs (sequences), including several runs that can last for more than a minute. Each run will produce various sounds.

If the exam you are taking involves using contrast material, then the doctor, nurse, or technologist will place the IV catheter (IV line) into a vein inside your arm or hand. The IV will be used for injecting the contrast substance.

You will be placed in the magnetic field of the M.R.I. device. The technologist will examine while using an outside computer in the room. You'll be able to communicate with the technologist using an intercom.

If your examination includes a contrast material, the technologist injects this into an IV line (IV) following an initial set of scans. They will also take additional photographs during or following the injection.

Once the examination is finished, The technologist might request you to sit until the radiology examines the results if further tests are required.

The technologist will cut off your IV line when the test is complete and place a small bandage over the insertion site.

The entire test is generally completed in about 60 minutes after imaging has been initiated.
