This document discusses various concepts and classifications related to abdominal trauma imaging. It begins with definitions of terms like window, Hounsfield units, and anatomy. It then covers classifications of injury to different solid organs like liver, spleen, kidney, and pancreas. Specific examples of injuries at different grades are shown, along with complications. Treatment options for some injuries are also mentioned.

This document discusses skull and facial fractures. It begins by defining a fracture as a partial or complete break in the skull bone, usually from direct impact, indicating substantial force was applied to the head. It then describes the anatomy protected by the skull - the brain, meninges, CSF. Skull fractures are more common in thin areas and develop at sites of increased force. Imaging helps assess the fracture pattern, type, extent and position. CT is usually best to evaluate skull fractures and brain injury while MRI is better for soft tissue injuries. Various fracture types - linear, depressed, basal, open vs closed - and classifications are described. Pediatric fractures like growing skull and birth fractures are additionally discussed.

#49: Subdural hematoma
In some instances: SDH appears isodense or minimally hyperdense to gray matter
The cause has been attributed to several factors, including anemia with a hemoglobin concentration of less than 10g/dL, admixture with CSF, disseminated intravascular coagulation.
