title: [Surgical echographic diagnosis of brain tumors].
abstract: Echographic examination of 43 patients was conducted during removal of tumors or during diagnostic operations. Brain tumors of supra- and subtontorial localization were detected. The use of an improved ultrasonic transducer and the transmission sonication method helps in identifying more exactly the character, size, and depth of the tumor as well as determining the condition of the ventricles and main arteries of the brain. The application of the improved method ensures the choice of an adequate surgical approach and reduces the traumatic character of the operation.
