magnetic resonance angiography (MRI)MRAIt is a type of x-ray that provides images of blood vessels inside the body MRA For the head to look at the blood vessels leading to the brain to check for a bulge (aneurysm), a clot, or a narrowing (narrowing) in the blood vessels. myhealth .
The importance of MRA
An MRI gives very detailed images of tendons and other organs, such as the brain, because the imaging waves pass through the bones.
Gives an MRI (MRAPictures of specific arteries and veins that doctors want to examine.
These detailed images provide doctors with information they cannot learn from a physical exam.
What are some common uses of MRA?
Doctors use MRA To examine blood vessels in key areas, including:
The abdomen (such as the kidneys and liver)
Legs and feet
– arms and hands
Doctors use MRA in order to:
Identify abnormalities, such as aneurysms in the aorta, whether in the chest, abdomen, or other arteries.
Detection of atherosclerotic disease (plaque) in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke.
Identifying a small aneurysm or arteriovenous malformationAVM) – an abnormal connection between blood vessels – inside the brain or elsewhere.
Detecting plaque disease that narrowed the arteries in the legs and helping to prepare for intravascular intervention or surgery.
Screening for disease in the kidneys’ arteries or visualizing blood flow to help prepare for a kidney transplant or stent placement.
Directing interventional radiologists and surgeons to perform repairs to diseased blood vessels, such as stent implantation or stent evaluation after implantation.
Detection of injury to one or more arteries in the neck, chest, abdomen, pelvis, or extremities after trauma.
Evaluation of the arteries feeding the tumor before surgery or other procedures such as chemoembolization or selective internal radiotherapy.
Determine the division of the thoracic or abdominal aorta or its main branches.
Demonstrate the extent and severity of coronary artery disease and its effects and plan intervention, such as coronary bypass and stenting.
Examination of the pulmonary arteries in the lungs for pulmonary embolism (blood clots, such as those that travel from leg veins) or pulmonary arteriovenous malformation.
Consideration of congenital malformations of blood vessels, especially arterioles in children (eg, malformations of the heart or other blood vessels due to congenital heart disease).
Assessment of stenosis and blockage of blood vessels.
Examination of arterial diseases, especially patients with a family history of it.
