CTA (CT Angiography)
A computed tomography angiography or CT angiography is a medical test in which a patient will receive an injection of a special dye through an IV in their arm or hand before undergoing a CT scan to produce detailed pictures of blood vessels and tissues.
Computerized tomography scans or CT scans are X-rays that create cross-sectional images of your body with a computer. The CT scanner consists of a machine with a tunnel. During a CT angiogram, a patient will lie on an examining table and pass in and out of the tunnel while the machine scans a specific part of their body. Combining a CT scan with the contrast material dye causes blood vessels and tissues a clinician wishes to study further to ‘light up’ for further examination.
