The aim of imaging of gunshot wounds is to: determine the path of the projectile/s; determine which tissues have been injured; estimate the severity of the injuries; identify any retained bullets and determine if any further investigations are required. Active haemorrhage must always be assessed for.
This case demonstrates how diaphragmatic injury can be inferred based on the trajectory of the bullet and the presence of blood on both sides of the diaphragm.
