Abstract
The authors tested a device that allows the tip of a needle to be visualized at color Doppler ultrasonography. The device directs an oscillating air column through a 0.016-inch inner-diameter hollow stylet, creating movement at only the needle tip. The movement is reliably and accurately displayed as a beacon of color at depths of 15 cm in vitro.
