Imaging in head injury Ø Plain X Ray ØCT scan Ø MRI Ø Angiography
X Ray Skull Ø Lateral view • Sphenoid Sinus – look for Fluid /air Level • Pneumocele • Double Densities • Linear Fracture Ø PA View • Frontal Sinus - look for Fluid /air Level • Pineal Shift
CT Scan ØIt is the most important investigation as it clearly depicts the extent of injury. ØUsually a Plain CT head with bone window is required ØMany times the first CT scan is done quite early a repeat CT scan should be done, preferably within 12 -24 hours after injury.
