Percutaneous punctures: a new radiological skill.

Abstract

Percutaneous aspiration or biopsy of abdominal masses is being performed with increasing frequency. Percutaneous puncture under fluoroscopic control is the simplest technique; it has the advantage that contrast media can be inserted into a cyst to outline its walls. Ultrasound can play an important role in guiding punctures if the mass or organ to be punctured cannot be seen on a radiograph or will be approached from an unusual angle. CT scanning is the preferred procedure for guiding the puncture of bone lesions and some small structures. The author concludes there may soon be a need for abdominal-puncture experts.
