[Use of ultrasound for diagnosis of foreign bodies of the brain].

With the aid of modern ultrasonic diagnostic devices experiments were conducted in order to receive signals from foreign bodies of a different composition, non-radiocontrast ones including. Experiments on 10 human brain preparations revealed the typical peculiarities of echo-signal from foreign bodies in the cerebral matter. In 30 adult mongrel dogs it was proved that foreign bodies can be diagnosed in the course of primary and secondary debridement of skull and brain wounds. It was found that the shape and size of the foreign bodies in the human brain can be most explicitly determined with the aid of a specially designed device having a high azimuthal resolution.
