One of the more common situations we will encounter in veterinary medicine is when a car hits one of our patients. Diagnostic imaging is often one of the first tools we will reach for when we see an “HBC” on the schedule. In this case we are going to consider the Roentgen sign of position. You will be given 2 radiographs to consider. In the first, look for what is missing in the abdomen. In the second, think about where the missing organ might be hiding. A VD projection was taken but was intentionally left out of this case to simplify the learning objectives.
