ABSTRACT

Ultrasound-guided punctures have been part of clinical routine for many years. Meanwhile the variety of biopsy needles has become huge, so that we can offer a special gadget for each indication and each organ. The results of investigations of the materials may help one to gain a general idea of the available possibilities and help to in the choice of the right one. In the special chapters about organs and tumour types one can find out which biopsy needles can achieve best results and guarantee the lowest possible level of complications. The path of access and possible injuries to important structures play an important role when choosing the size of the biopsy needle and the technique of puncture. Besides the results of comparative studies, the personal experience of the interventionalist is an important factor for choosing the right material because the individual's manual skills have an important impact on the results.
