Blunt chest trauma typically occurs as part of polytrauma, usually secondary to motor vehicle accidents, sports related injuries or defenestration in Western Europe. Each chest compartment may be responsible for immediate and/or delayed complications, thus requiring a dedicated systematic and comprehensive analysis. The use of image post-processing is mandatory in order to not overlook a potentially severe injury. The purpose of this paper is to review the technical considerations of multidetector CT, and the imaging features and interpretation method for each chest compartment, in order to generate an adapted report.
