Skull radiographs are rarely performed except as part of skeletal surveys in suspected non-accidental injury or myeloma.
X-ray skull: May be used if CT is not available in skull fractures, however, depressed skull fractures may be difficult to visualize by X-ray skull and it cannot be used to evaluate for intracranial injuries
PN Sinuses
- On plain radiographs the normal sinuses are transradiant because they contain air.
- Plain films have a role in showing mucosal thickening, fluid levels and fractures.
- In most sinus disease, CT is the preferred technique.
- MRI also demonstrates the sinuses well, but is rarely required as the primary investigation
