Computed tomography of the lower limb arteries is an accurate and highly effective diagnostic imaging technique in detecting vascular diseases of the lower limbs.

Computed tomography angiography of the lower limbs or CT angiography of the lower limbs is an imaging method that examines the vascular system using high-intensity X-rays. Contrast dye is injected into the arterial system from the femoral artery to the iliac artery triad, then X-rayed to take pictures of each cross-sectional vessel and reconstruct the image of the vascular system in three-dimensional space.
