Needle localisation of non-palpable breast lesions

Localisation of non-palpable breast lesions using a simple inexpensive apparatus which can be constructed in most hospital workshops is described. A single-needle bi-plane technique is used. The details of the apparatus are given and the radiographic control of the insertion of the needle is described, particular emphasis being placed on practical details in order to assist those who are unfamiliar with the technique. The importance of localisation for the pathologist is emphasised.
