[Gallstones as depicted in the sonogram and radiogram. A comparative study].
Eighty-seven unselected gall stones were examined radiologically and by ultrasound in vitro. No relationship of diagnostic value could be established between the amount of calcification and stone demonstration, the sonogram being influenced by the size of the stone, its surface contour and its position in the ultrasound beam. Sonography is therefore not suitable for selecting those patients on whom litholysis could be carried out. Sonography appears to be useful only in a negative way by establishing the exact size of the concretion.
