Advanced MRI

The medical team at CIN has changed the landscape for people suffering with mild to moderate TBI. Traditional methods of imaging brain disorders may lack diagnostic specificity, which may lead to errors and delays in diagnosis while frequently missing critical treatment windows. Advanced imaging with MRI has been called the “equalizer” for its ability to detect the presence of different subtypes. Our methods include two unique core imaging strategies:

Susceptibility Weighted Imaging (SWI)

SWI is 3 to 6 times more sensitive than traditional MRI imaging, revea2ling even the smallest hemorrhage.

Diffusion Tensor Imaging (DTI)

DTI is even more sensitive than SWI. It allows the CIN team to identify other chronic, degenerative processes that cause test results to remain abnormal (continuing to show signs of disorders) despite real functional recovery.

Magnetic resonance imaging has come a long way from the familiar black-and-white images. Today’s advanced neurovascular imaging techniques track the flow of liquid in the brain, identifying gaps and areas of trauma. Two such techniques—Susceptibility-Weighted Imaging (SWI) and Diffusion Tensor Imaging (DTI)—are used with patients of the Center for Integrated Neurology.

In a DTI image, regions highlighted in blue indicate nerve (axonal) injury.

Susceptibility-Weighted Imaging (SWI)

The image at right shows a comparison of a traditional MRI technique, FLAIR (a), to an SWI image (b). Both images were taken of the same patient. Note the visible ‘gaps’ in (b) that would have gone undiagnosed were a clinician to use only (a). The SWI image is possible through the use of algorithms that differentiate the densities of adjacent tissues. While signal density forms the basis of all MR scans, including (a), the SWI scan (b) is 3-to-6 times more sensitive as it accounts for the susceptibility of all brain elements, including hemorrhages – hence the name susceptibility-weighted image. SWI is clinically appropriate in the diagnosis of: TBI, Tumors, Stroke and Hemorrhage, Multiple Sclerosis, Vascular Dementia, Sturge-Weber disease and other brain disorders.

Diffusion Tensor Imaging (DTI)

DTI is appropriate for imaging the brain’s neural tracts for signs of injury or disorder. DTI works by measuring the diffusion of water through tissue. Measurements are isolated to identify the preferred direction of flow, which allows for the isolation of neural tracts from the brain’s white matter. DTI is the most sensitive MR approach currently available and can be used to identify tract-specific lesions caused by TBI. In one study, DTI scans found tumors, hemorrhages and obstructions in 63 of 179 patients that were undiscovered using traditional MRI scans (sciencedaily.com, 4/23/2009).

Both SWI and DTI MR applications are available to our patients.
