When it comes to radiology, the term echogenic refers to material that allows ultrasound waves to be reflected. The term echogenicity can be understood as the property of a given material (an organic tissue, or a blockage cannula, for example) to reflect ultrasound and generate echoes, which in turn generate echographic images, also called sonographic images, allowing the echogenic object to be visualized more clearly on the image formation screen. Sonovisible is also a term used to describe materials with similar properties.
