[Ultrasonographic guidance of percutaneous biopsies and punctures].
Real time ultrasonography is routinely used for guidance of percutaneous punctures towards small targets, with three goals: 1. Aspiration biopsies for analysis of an abnormality detected with ultrasonography. 2. Injection of contrast media inside normal structures (urinary, biliary or pancreatic tract) or abnormal collection (cysts, pseudocysts). 3. Treatment by percutaneous sclerosis, aspiration, decompression, drainage.
