MR Angiography
What is Magnetic Resonance Angiography?
MRI is a method of producing extremely detailed pictures of body tissues and organs without the need for x-rays. The electromagnetic energy that is released when exposing a patient to radio waves in a strong magnetic field is measured and analyzed by a computer, which forms 2D or 3D images that may be viewed on a computer monitor. MR angiography (MRA) is an MRI study of the blood vessels. It utilizes MR technology to detect, diagnose and guide the treatment of heart disorders, stroke and blood vessel diseases. MRA provides detailed images of blood vessels even without intravenous contrast medium. Frequently, a special form of intravenous contrast, gadolinium, is used which markedly improves the quality of the MR images of the vessels.
Why is Magnetic Resonance Angiography an excellent alternative to Catheter Angiography?
MRA provides detailed images of blood vessels without having to insert a catheter directly into an artery. There is no significant recovery time and cost is substantially less when compared to standard angiography. A very small amount of gadolinium based contrast medium may be injected, unlike catheter angiography which uses a large volume of iodine-based contrast. MR contrast is very safe and the risk of an allergic reaction is extremely low.
How is the procedure performed?
You will be placed on a special table and positioned inside the opening of the MRI scanner. A typical exam consists of 2 to 6 imaging sequences, each taking from 2 to 10 minutes. Each sequence provides a specific image orientation and a specified degree of image clarity or contrast. Depending on the type of exam being done, the total time needed can range from 10 to 60 minutes, not counting the time needed to change clothing, have an IV put in, and answer questions. When contrast medium is needed, a substance called gadolinium is given by IV injection during one of the imaging sequences.
