Real-time ultrasound (US)-guided biopsies and drainage procedures require constant visualization of the needle tip. Ensuring optimum needle tip visualization is paramount to the success of these procedures. The authors have found that pumping the stylet in and out of a stationary needle shaft increases the echo-genicity of the needle shaft and tip, thereby facilitating needle localization. This technique, which we have termed "the pump maneuver," is a quick, useful, and atraumatic adjunct to be considered during US-guided percutaneous needle biopsy and drainage procedures.
实时超声（US）引导下的活检和引流操作需要持续观察针尖。确保最佳的针尖可视化对于这些操作的成功至关重要。作者发现，将针芯在固定的针杆内反复抽动可增加针杆和针尖的回声，从而便于针头定位。我们将这种技术称为“抽动操作”，它是一种快速、有用且无创的辅助方法，在超声引导下经皮穿刺活检和引流操作中应予以考虑。
