Attenuation in blood, urine, and biologic fluids is described as:

Explanation:
Attenuation is the weakening of an ultrasound beam as it travels through a medium due to absorption and scattering. Blood, urine, and other biologic fluids are largely water-based and contain few structures that scatter or absorb sound strongly. Because of this, the ultrasound energy passes through these fluids with little loss, so their attenuation is described as low. This is why fluid-filled areas tend to transmit sound easily and appear dark on ultrasound. Higher attenuation occurs in denser or more complex tissues, but fluids remain comparatively low in attenuation.
