Computed Tomography Angiography (CTA)

A CTA scan is a quick special type of CT scan that allows the Radiologist to see detailed images of your blood vessels using iodinated contrast. A CTA exam helps evaluate how blood flows through arteries and veins. CTA studies can discover narrowing, blockages, aneurysms and blood clots.

Frequently Asked Questions

Computed Tomography (CT)

A Computed Tomography (CT) exam is a medical imaging test that helps Radiologists see detailed pictures of the inside of your body. It uses X-rays and computer technology to create cross-sectional images of organs, bones and blood vessels.

Magnetic Resonance Imaging (MRI)

MRI is a medical imaging exam that uses nuclear magnetic resonance to visualize internal structures of the body in detail. There is no radiation. MRI’s help Radiologist examine organs, muscles, joints,ligaments, muscles, bones, brain, spine and soft tissue anatomy. An MRI creates two-dimensional or three-dimensional images of any part of the body. MRIs provide good visual contrast between the fat and water content of the body which makes them especially useful in revealing abnormalities like tumors, inflammation and infection.
