Abstract
Notes:
- CT scan often does not show the severity and extent of cerebral damage. Does not detect acute ischemia well.
- In the guidelines for imaging children with suspected physical abuse published by the American College of Radiology, an MRI is suggested if the CT is negative, or to help determine timing.
- While SBS can be missed, it is also sometimes overdiagnosed, with parents or caregivers falsely accused.
- "The demonstration of associated cerebral ischemia acutely may be the key to the diagnosis of SBS."
- Diffusion weighted imaging may help distinguish ischemia from traumatic axonal injury.
- Cerebral ischemia may be one of the mechanisms leading to irreversible damage in SBS.
- The length of a hypoxic episode is related to the severity of the brain damage.
- MRI is superior to CT in establishing timing.
