Tilting enhances visualization of lower extremity veins with duplex colour flow imaging.
The present paper presents the results of a comparative analysis of the number veins and of the ease of visualisation of below the knee as displayed by colour Duplex scanning in both legs of 10 normal individuals in the horizontal and 40 degrees foot down tilted position. Foot-down tilting improves the ease of visualisation of lower leg veins by 38% and the number of visible branches by 28%. Therefore, this technique should preferably be employed in the diagnosis of deep vein thrombosis in order to improve diagnostic accuracy.
