Imaging Of Traumatic Brain
Injury
Learning Objectives
? To learn mechanisms of various TBI
? To identify common TBI
? To identify complications of TBI
Epidemiology
? 10 million people suffer from TBI every year globally
? 10% are fatal
? 5-10% sustain chronic disabilities
? 20-25% have moderate disabilities
Modes of injury
? Missile / Penetrating injury
? Non missile injury ? road traffic accidents, falls.
? Ground level falls in children and elderly adults
Classification
Primary injury
Secondary injury
? occurs at the time of injury
? Due to mass effect
? Fractures
? Herniations
? Intracranial hematoma
? Edema
? Contusions
? Ischemia
? Lacerations
? Vascular injuries
? DAI
Modalities
? Radiographs / X-rays
? NCCT
Can only identify fractures
Preferred screening tool
Intracranial injuries can not be
Bone injuries
detected
Parenchymal injuries
? CT Angiogram
? MRI
Penetrating injuries
DAI
Dissection
Normal CT with non explainable
Cervical spine fractures ? vertebral neurological deficits
artery injuries
Guidelines for NCCT
GCS 3-8
For rest
? get CT as soon as possible
? fall in GCS
? Initial scan is normal then get a
? Depressed / open fractures
repeat CT if patient deteriorates ? >2 episodes of vomiting
neurologically
? Skull base fractures
? If initial scan is abnormal and
patient is stable, get a repeat CT ? Dangerous mechanism
24-36 hours to check
Skul Fractures
Depressed fracture of frontal bone
associated with haemorrhage in
frontal sinus
Depressed comminuted fracture
with marked inward displacement of
fragments
Intracranial Injuries
Air
Blood
Bone

Secondary effects
Take Home Points
? Identify the mode of injury
? Identify the pattern of injury
? Look for primary injury
? Secondary injury
? Actionable findings
