EXAMINATION OF THE APPLICABILITY OF THE U LTRASONIC METHOD AT PIG

The application of sonography at pigs has hitherto been confined to gy necological questions. In this examination applicabilities of the ultr asonic method are examined from the internistical point of view. The s onographical normal picture of organ structures and the value of this method as aid for diagnosis of clinically manifest changes are shown. A 5MHz linear-scanner and a 3,5 MHz convex-scanner (76-degrees) turned out to be suitable. 112 patients of the Clinic of Internal Medicine I I and additional 35 healthy pigs were examined. Preliminary examinatio ns were made with isolated organs, which were scanned in a water bath. The sonographical findings of pathological changes could be secured b y the postmortem findings. Within the scope of the main examinations, manners of representation and sonographical appearance of liver, gall- bladder, kidneys, urinary-bladder, stomach, lungs, muscular system, sp ine and transponder were elaborated. The standardized measuring of liv er and kidney proved statistically secured dependencies among the meas uring data and were significantly related with the body-weight. The ul trasonic guided puncture of gall-urinary bladder and of liquor crebros pinalis could be carried out successfully.
