CT (computed tomography)
angiography (CTA), is specialized exam utilizing the latest
engineering and computer technologies to produce images of blood
vessels. Compared to traditional angiography, where a catheter is
placed directly into the artery being studied, CTA is less
invasive, requiring injection of iodine-based contrast (dye) into
a vein in the arm, and is routinely performed in an outpatient
setting.
CTA is most commonly used to study
the aorta and blood vessels supplying the lungs and kidneys. With
the advent of multi-detector CT, faster scanners with higher
resolution can image smaller vessels, including the arteries of
the brain and extremities. With a 16-detector CT, even the
coronary arteries can be evaluated. 3D images are generated with
the use of sophisticated software.
Main Street Radiology
installed the first 16-detector CT in Queens. With the most
advanced software available, we are able to perform high
resolution 3D CTA.
