Extended field of view and 3D in the diagnosis of breast pathology is relatively new software in Ultrasonography. It is the ability to collect images from different segments of the human body, while the operator performs a scan with the transducer continuously along the segment of the body examined. The images are stored on the computer, processed and presented on the computer screen. This technical advance applied to breast ultrasonography has improved the documentation of the lesion by 79% in large masses and 69% in breast implants.

The indications for this technique are benign pathology, malignant pathology (especially in large tumors) and post-surgical control (breast silicon implants).

The limitations of extended field of view are:

- No color Doppler application when use it and no 3D possible with extended field of view

This technique also allows to measure lesions, especially large lesions such as large simple cysts, giant fibroadenomas, phylloides tumors, hematomas, abscesses, limph nodes, etc.

A major application is in breast silicon implants, allowing us to see the entire implant and understand its shape, size, structure, and any concomitant pathology such as breaks, contractures, and so on, and the presence or absence of tumors in breast tissue.

Besides 3D breast application let us analyze a lesion in 3 planes: longitudinal, transverse and especially coronal (this is not possible in 2D view). With 3D, we can better analyze the edges and content of a lesion and document the commitment of neighboring tissues and analyze much better vascularization and the type of blood vessels of lesion especially in malignant tumors or limph nodes, in which we can analyze better if it's neovascular vessels.

Extended field of view and 3D let us improve the lesion documentation especially in big lesions and breast cancer.
