The recent expansion of elastography amongst all the manufacturers has led to a rocketing increase in the number of examinations whose results are rather disappointing and very uneven. Some manufacturers (the pioneers) have a great experience, and they perfectly master this technique which was long frowned upon. There is an obvious discrepancy in the results which is partly linked to the various types of equipment available to the users, but there is also great unevenness due to the fact that this technique is very much operator dependent without training. A minimum expertise and training should allow the limitation of disparity in the results obtained and tone down that dependence. To recall the basic principles of elastography and make clear once again the technical recommendations for the carrying out of the examination has seemed more pertinent and essential in order to ensure the good use of this remarkable technique which has become an unavoidable part of the echographic examination of breasts. Part of the recent bibliography presented here bears witness to the good clinical results of this technique, and we have no need to repeat and reproduce them.
