title: [Two-dimensional echocardiography. Principles, techniques, and anatomical comparisons].
abstract: This article introduces bidimensional echocardiography. The main sections are reviewed. A brief comparison between M-mode and 2 D echocardiography is proposed showing that the two techniques are really complementary to one another. Judging by the many applications of M-mode echocardiography in recent years, one may safely expect considerable developments for the bidimensional echocardiography which, in its very first steps, already appears irreplaceable.
