Focal versus diffuse injury. Deceleration Injuries (Diffuse Axonal Injury): Your skull is hard and your brain is soft. With rapid acceleration–deceleration of the head, shearing forces cause mechanical axonal damage. This is a much higher frequency than previously thought and suggests that most cases of post-traumatic hypopituitarism remain undiagnosed and untreated. The severity and outcome of a DAI depend on the extent and degree of damage to brain structures and can be classified as mild, moderate, or severe DAI. The sensitivity to depict nonhemorrhagic diffuse axonal injury is 0% at CT versus 11% at MR imaging, whereas the detection rate of hemorrhagic diffuse axonal injury is 22% at CT versus 47% at MR imaging .
