Neuro-Imaging in Brain Injury Lecture Outline

• Optimal TBI protocol – Standard – Advanced

• Imaging findings highly specific for head trauma • Imaging findings possibly related to head trauma • Imaging findings more likely relating to head trauma?

– Atrophy • Global • Hippocampal • Cortical

– White Matter Shearing – DTI (Diffusion Tensor Imaging)

TBI Protocol • CT: assess life threatening conditions in ER

– Bleeds, fractures, midline shift

Subdural Hematoma Subarachnoid Hematoma Intraparencheymal Hematomas

Value of CT

• Essentially nondiagnostic for mTBI

• Soft Tissue Swelling! Commonly missed by radiologists

• Some findings on CT will resolve by the time MRI is performed (Subarachnoid Hemorrhage, Subdural hemorrhages)

Prognosis of Subdural and Subarachnoid Hemorrhage (Often only seen on initial CT)

Subdural Hematoma Subarachnoid Hemorrhage

Mortality rate as high as 60%, which has improved recently with recent medical and surgical advances (Alagoz, Yildirim et al. 2017) However, there remains risk for significant morbidity with functional recovery rates from surgically treated acute subdural hematomas ranging from only 19-45% (Bullock, Chesnut et al. 2006, Tallon, Ackroyd-Stolarz et al. 2008).

A high mortality rate of 35-40%, despite neurosurgical treatment advances, has been reported following SA hemorrhage (Pothiawala 2012). Twenty-five percent of patients develop moderate depression, 50% of survivors report that they think that their personality has changed, generally for the worse, the cases reported being mostly weakness, excessive irritability, memory difficulties, daytime drowsiness and insomnia” (Daniere, Gascou et al. 2015).

TBI Protocol

• MRI – Only way to completely assess prognosis, full extent of damage, can be done

as outpatient.

MRI optimal protocol Standard Imaging – 3T magnet (better camera lens) – SWI (hemorrhage) – Thin section, triplane (contusions and shearing) Advanced Imaging – Volumetric Software (atrophy means injury) – DTI (White matter tract damage) – Perfusion (Blood flow) – Other? (MRA, spectroscopy, fMRI) – Time and cost constraints?

Why Advanced Imaging?

Conventional MRI is insensitive for traumatic brain

injury with only 27% of patients demonstrating

findings. (Yuh et al., 2013) Therefore advanced

imaging is indicated which can identify pathology

not present on conventional sequences. (Vanier et

al., 2020) (Osborn, 2017)

The corpus callosum is the largest white matter fiber tract of the brain and the only significant fiber tract connecting the right and left hemispheres. Without the corpus callosum, the two halves

(hemispheres) of the brain cannot communicate. Injury to this vital structure is a very poor prognostic sign.

When to Image? (EARLY!)

• 70% of Hemorrhagic DAI resolves on follow-up MRI

• 30% of Non-hemorrhagic DAI resolves

• 30% of contusions resolve on subsequent MRI and a volume reduction of 44% on average one year following trauma.
