what is the appropriate term to describe abnormalities on diagnostic ultrasound?
attenuation
intensity
density
echogenicity

Explanation:

• Attenuation: Refers to the reduction in the intensity of a wave (like an ultrasound wave) as it travels through a medium. It's more about the wave's weakening rather than describing abnormalities.
• Intensity: Measures the power per unit area of a wave. While related to ultrasound waves, it's not the term specifically for describing abnormalities.
• Density: A physical property of matter (mass per unit volume). Not directly related to describing ultrasound - based abnormalities.
• Echogenicity: In diagnostic ultrasound, echogenicity refers to the ability of tissues to reflect an echo (ultrasound wave). Abnormalities can be described based on their echogenicity (e.g., hyperechoic - more reflective than surrounding tissue, hypoechoic - less reflective).

Answer:

echogenicity
