Abstract
Percutaneous aspiration or biopsy of abdominal masses is being performed [in humans] 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 of organ to be punctured cannot be seen on a radiograph or will be approached from an unusual angle. CT [computed tomography] scanning is the preferered procedure for guiding the puncture of bone lesions and some small structures.
