The Imaging core of the Stroke Institute provides neuroimaging services for all areas of stroke and cerebrovascular disease. Our core is led by stroke recovery arm led by Dr. Muhammad Haque.
The primary emphasis of the clinical and translational MR stroke imaging core is to develop qualitative and quantitative surrogate markers of the post-stroke prognosis, secondary degeneration, recovery, and treatment efficacy.The neuroimaging scientists at the Magnetic Resonance Image Processing Stroke Core are ready to assist you with your clinical and preclinical imaging needs by designing experiments, optimizing image acquisition protocol, and data analysis. Imaging protocols are designed to evaluate ischemic and hemorrhagic post-stroke lesion volume, white matter integrity, chronic neuronal loss, rate of brain atrophy, cerebral blood perfusion, neuronal circuitry, and metabolic profile.
Typical image acquisition protocol includes: high resolution 3D anatomical images, diffusion tensor imaging, arterial spin labeling, quantitative susceptibility imaging, magnetic resonance spectroscopy, resting state functional MRI.
Quantitative image processing includes: Voxel based morphometry, diffusion tensor matrix, deterministic and probabilistic tractography, cerebral blood volume and cerebral blood flow, lesion segmentation, neuronal network, cortical thickness, iron concentration and metabolite concentration.
We apply matlab based processing code using commercial and freeware software packages such as Analyze, e-film, SPM, FSL, DTI_Studio, STI etc.
The Imaging Core also serves as the imaging analysis center for international stroke trials including the following:
Quantitative Susceptibility Mapping allows for quantitative volumetrics of hematoma in patients with intracerebral hemorrhage
Tractography of the corticospinal tracts
Picture of cerebral blood flow
