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
