Abstract
The intrinsic ultrasonic attenuation of a gallstone [human] is an important factor in determining the degree of shadowing. B scans in vivo and in vitro demonstrated that stones with higher attenuation also show the most shadowing. Attenuation can be correlated with physical structure; more highly attenuating stones tend to have the largest percentage of crystalline material, a larger average crystal size and a more rigid structure. The authors recommend that higher frequency transducers be used where possible if nonshadowing structures are seen in the gallbladder.
