[ Radiological anatomy of the breast]

The macroscopic anatomy of the breast is often not well understood; it is the reason why the radiologic images formation of this organ needs to be explained. This work is based upon anatomical-radiological confrontations, which allow to separate the two main compartments of the gland, the fibroglandular tissue and the adipose tissue, and to study the limits of these two components. Their different proportions are at the origin of different patterns leading to a simple classification of non-pathologic breast X-rays. This classification makes easier the diagnosis of abnormalities, especially of tumoral origin.
