- A simple and inexpensive tissue phantom is easily created for use in training residents and fellows to perform multiple procedures in the liver. -Enhancements including respiratory motion and simulation of target lesions, abscesses and infected gallbladders customize the teaching experience. -Method of phantom creation and application to teach targeted and nontargeted biopsies, percutaneous drainage of liver abscesses and percutaneous cholecystostomy are demonstrated.

1. Creation of liver tissue phantom    a. Bovine liver and porcine chest wall preparation    b. Phantom enhancements simulating physiologic and pathophysiologic conditions       -Target lesions (simulated metastases)       -“Respiratory motion” simulator       -Liver abscesses       -Artificial gallbladder          -Both liver abscess and gallbladder models can be repeatedly punctured and drained in same session 2. Sample teaching materials     a. Didactic presentation content teaching performance of each procedure:        -Nontargeted liver biopsy        -Targeted liver biopsy        -Percutaneous cholecystostomy        -Liver abscess drainage 3. Hands-on teaching demonstration     a. Video and still image displays: use of models for hands on teaching         -Sonographic appearance of simulated pathology         -“Pus”, “bile” aspiration         -Demonstration of model durability for repeated procedures
