[Indications and limitations of ultrasonic investigation in abdominal pathology].

Investigation of the abdomen by ultrasounds must now be included among routine tools in abdominal diseases. All abdominal organs, with the exception of the intestine with its gas content, are open to investigation with this technique which combines harmlessness and rapidity with its unique possibility of making differential diagnosis possible in structures with different tissue constitution. The limitations are to be sought more in the examiner's interpretational capacities and in the apparatu's limited resolution power rather than in the technique proper.
