Although ultrasound guidance is extensively used in percutaneous interventional procedures, the limitations of B-mode, gray-scale sonographic guidance can restrict clinical use. Little attention has been paid to the use of color Doppler sonography during such procedures.

There are several ways in which color Doppler sonography can facilitate percutaneous procedures that involve insertion of a needle or catheter. The advantages of color Doppler sonography include the following: (a) better visualization of the shaft and tip of the needle, especially in solid, echogenic lesions, when the needle is moving, or when the beam-needle angle is narrow; (b) improved targeting of either vessels or non-vascular structures (ie, biliary ducts) to be punctured; (c) avoidance of interposed vascular structures and highly vascular areas during puncture of lesions; (d) improved visualization of poorly echogenic catheters, allowing proper placement; and (e) prompt detection of complications, including active bleeding, after withdrawal of the needle.
