Describing radiographic lesions is the foundation for any radiographic interpretation. Without being able to properly describe a radiographic lesion or finding you will not be able to form an accurate differential. When trying to come up with a way for students to recall the important aspects of radiographic description I came up with an acronym LESION. Each letter applies to a different component of describing a radiographic lesion or finding. The acronym is primarily for intraosseous lesions, but can also be applied to other lesions or findings as well.
LESION stands for location, edge, shape, internal, other, and number.
