"In ultrasound, the attenuation coefficient (α) is estimated from the gradient of attenuation against the frequency of ultrasound with units of dB MHz-1 cm-1. In soft tissue, ultrasound attenuation is 0.5 to 0.75 dB MHz-1 cm-1 4. In fatty liver and fibrotic liver, the attenuation coefficient increases. In the case of breast tissue, the attenuation coefficient decreases in fatty tissue and medullary carcinoma. It increases in fibrotic tissue and ductal carcinoma of breasts 1."

"The linear attenuation coefficient will vary with substance density, whereas mass attenuation coefficient will not. As an example, water and ice would have different linear attenuation coefficients but the same mass attenuation coefficient."
