Ultrasonically guided percutaneous puncture technique

Abstract

Abstract Ultrasound provides anatomical sectional pictures of organs and lesions on the basis of which optimum direction and depth of puncture can be established. The use of a specially designed transducer with a central canal through which the needle is introduced ensures the maintenance of the correct direction during the procedure. A number of areas of applicability are discussed and it is found that as an aid in percutaneous puncture ultrasound has essential advantages when compared to radiology.
