Color duplex (color flow Doppler) has largely replaced venograms as it provides real-time imaging without the need for radiation exposure or contrast dyes. It is a non-invasive technique that uses ultrasound to visualize blood flow in veins and arteries, making it a safer and more patient-friendly option compared to traditional venography.
