          TERMINOLOGY

          • Definitions

            • Echogenicity: Echo pattern, internal characteristics of mass, defined relative to subcutaneous fat
            • Hyperechoic = echogenic: More echogenic than subcutaneous fat
            • Hypoechoic: Less echogenic than subcutaneous fat
            • Heterogeneous: Mass with both hyperechoic and hypoechoic portions, mixed echogenicity
              • Distinguish from complex cystic and solid, which has both anechoic (cystic/fluid) and hypoechoic (solid) components
