Imaging Sciences (Radiology)

MR Angiogram

Magnetic resonance imaging (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 two- or three-dimensional images that may be viewed on a TV monitor. MR angiography (MRA) is an MRI study of the blood vessels. It utilizes MR technology to detect, diagnose and aid the treatment of heart disorders, stroke and blood vessel diseases. MRA provides detailed images of blood vessels without using any contrast material, although today a special form of contrast usually is given to make the MR images even clearer. The procedure is painless, and the magnetic field is not known to cause tissue damage of any kind.

MRA Head

Head MR Angiography is usually done without
contrast. The technique is completely noninvasive and
provides a good visual aid.

MRA Neck

Neck MRA in this case has been performed with contrast. It
covers from the aortic arch to the Circle of Willis.
