CT Scan Left Lower Limb Angiography (CTA)
Understanding CT Scan Left Lower Limb Angiography (CTA)
What is CT Scan Left Lower Limb Angiography (CTA)?
A Computerized Tomography (CT) angiography left lower limb test is a medical imaging technique used to detect the blood vessels that carry blood to your left leg. A high-contrast medium is injected before the scan to get clear images. The CECT is recommended when you have painful cramps in leg muscles, leg numbness, difficulty walking, and extreme soreness.
CT angiography of the left lower limb is a rapid and reliable technique. The contrast medium may cause temporary skin redness and itching after the scan. Abnormal test results indicate thrombosis, pseudoaneurysm, arterial laceration, and intimal flaps. Please inform your doctor or X-ray technician if you are pregnant before taking the test. It is better to remove all metal objects like jewelry to avoid obstructing the imaging
