What are the Diagnostic Tests Used for Traumatic Brain Injuries

Due to the long term effects, difficulty of diagnosis, and varying degrees of severity, Traumatic Brain Injuries are currently among the most frightening and serious injuries commonly associated with automobile, motorcycle, and trucking accidents.

Because of the possible repercussions of a Traumatic Brain Injury, diagnosis is of the utmost importance. However, certain types, such as Diffuse Axonal Injuries, of Traumatic Brain Injuries are exceedingly difficult to diagnose with the use of only CT and MRI scans because the damage to the brain is microscopic, rather than macroscopic. In order to diagnose Diffuse Axonal Injuries, a doctor or radiologist must notice small bleeds in the corpus callousem or cerebral cortex.

Susceptibility Weighted Imaging (SWI)

Susceptibility Weighted Imaging uses a type of contrast in MRI different from traditional imaging techniques. A phase image and a magnitude image of the brain are taken. These two images are then combined to create an enhanced contrast magnitude image referred to as a SWI. SWI is particularly helpful for the evaluation of diffuse axonal injury (DAI), which are not routinely visible on CT or conventional MRI sequences. “SWI exploits the magnetic susceptibility differences between tissues, resulting in phase differences between regions containing paramagnetic deoxygenated blood products (deoxyhemoglobin, intracellular methemoglobin, and hemosiderin) and surrounding tissue. The signal-intensity cancellation in the magnitude images and the additional suppression from the SWI filtered-phase images produce a hypointense signal in areas of acute and early subacute hemorrhage.” SWI is crucial in the detection of DAI due to the difficulty typical diagnostic studies have of revealing such injuries. SWI is typically run at a high resolution and is sensitive to gray matter/white matter boundaries which allow the radiologist or interpreting physician to see the microscopic bleeds which other diagnostic tools tend to miss.

Diffusion Tensor Imaging (DTI)

DTI is a form of Diffusion Weighted Imaging (DWI), which is a well-established magnetic resonance imaging (MRI) method for diagnosing cerebral ischemia. DTI allows direct examination of aspects of the tissue microstructure and provides a detailed view of the brain, and enables mapping of the orientation of white-matter tracts. DTI has been shown to adeptly image the brain’s white matter structures (such as the Corpus Callosum), the most important location of pathology in TBI. Additionally, DTI allows physicians to quantify white matter integrity (and because TBI frequently involves white matter injury) and therefore can be used to demonstrate injuries and pathology which can be attributed to mild TBI.
