[16] Typically duplex ultrasound scan is the only investigation required for ...

[citation needed] Modern computerized tomography (CT) scanners provide direct imaging of the arterial system. Studies have shown the sensitivity and specificity of CT in identifying lesions with >50% stenosis to be 95% and 96%, respectively. [58] As such, CT may be considered as an alternative to invasive angiography.
It travels up the leg and medial side of the thigh to reach the groin, where it drains into the common femoral vein. [32] Along the length of the GSV, it [clarification needed] receives numerous tributaries (from the subcutaneous layer) and drains into the deep veins via the perforator veins. The "eye sign"
