Objective: Intraoperative ultrasound can be trained only in the OR until now. The situation is not ideal for teaching due to the lack of time. There ist a need for special models to teach and test ultrasonic skills of young neurosurgeons also outside the OR.

Methods: We created a semibiologic model using a fresh pig brain which was treated with different methods. 1) injection of graphit and glue to simulate a soft tumor specimen 2) inflating of a special constructed fluid filled ballon device to simulate a cyst. Puncture technique could be used if asked for. 3) no treatment to simulate normal conditions. 4) insertion of a hard material to simulate a foreign body. The complete medical staff was tested individually with this test battery.

Results: Only 2 of 20 tested persons can give the correct diagnosis in all cases. In all other physicans the usage of ultrasound and elastography was limited. All participants accepted the meodel as good for training and education. The most important fact is to create the artificial lesion without inflating air.

Conclusions: The presented model ist suitable to train ultrasound as well as elastography. Especially new ultrasiund techniques can be teached and trained slowly and in a stress free manner without the time pressure inside the OR.
