What is CT angiography of lower limb?
Computed tomography angiography (CTA) is an accurate and rapid diagnostic tool for detecting vascular injuries in lower extremity trauma, including arterial laceration, transection, dissection, thrombotic occlusion, pseudoaneurysm, arteriovenous fistula, and intimal flaps.
What is CT peripheral angiogram?
Lower-extremity computed tomographic (CT) angiography (ie, peripheral CT angiography) is increasingly used to evaluate patients with peripheral arterial disease. It is therefore increasingly important for all vascular specialists to become familiar with the strengths and limitations of this new technique.
How do you do lower limb angiography?
How is the Lower Extremity Angiography Test Performed?
- A numbing medicine (anesthetic) is injected into the skin over an artery.
- A needle is placed into that artery.
- A thin plastic tube called a catheter passed through the needle into the artery.
- Dye flows through the catheter.
- X-ray images are taken of the artery.
How CT angiography is done?
CT angiography is a type of medical test that combines a CT scan with an injection of a special dye to produce pictures of blood vessels and tissues in a part of your body. The dye is injected through an intravenous (IV) line started in your arm or hand.
What is difference between angiography and CT angiography?
CT angiography vs angiogram The main difference between the two procedures is that while a standard angiogram involves a catheter being inserted into the artery and to the area being studied, a CT angiogram does not require the insertion of a catheter.

How accurate is CT angiography?
Results: The diagnostic accuracy of CT coronary angiography was evaluated regarding true positive, true negative values. The overall sensitivity and specificity of CT angiography technique was 100% (95% confidence interval [CI]: 39.76%–100%) and 91.30% (95% CI: 79.21%–97.58%).
