[Contribution of ultrasonics in the evaluation of abdominal tumors in children].

Twenty-eight children with abdominal tumors were examined ultrasonically. Real-time ultrasonography proved particularly useful in infants. In most cases ultrasonography shortened the diagnostic procedure by giving accurate images of the tumor's limits, size, contents, and origin. The method yielded an overall diagnostic accuracy rate of 89%. Moreover, ultrasonography is a reliable and safe means of monitoring abdominal tumors during and after therapy. In 1981, plain roentgenograms, intravenous urography with cavography and ultrasonography should be sufficient in the standard radiologic approach of most children with abdominal tumors.
