Study Notes
Initial TBI Assessment
- Essential elements for initial traumatic brain injury assessment include various imaging techniques to detect structural damage.
- Non-contrast Brain Computed Tomography (CT) effectively identifies skull fractures and brain hemorrhages.
- Advanced MRI testing for TBI includes Diffusion Tensor Imaging (DTI) 3D Tractography, which assesses white matter integrity.
Magnetic Resonance Spectroscopy (MRS)
- Common metabolites measured during MRS include N-acetylaspartate (NAA), choline, and creatine.
- Specific metabolites or markers not typically measured by MRS need to be identified in the context of TBI assessments.
Arterial Spin Labeling (ASL)
- Arterial Spin Labeling MRI (ASL) is a non-invasive technique that quantitatively measures cerebral blood flow, contrary to being labeled invasive.
Functional MRI (fMRI)
- Two varieties of functional MRI techniques are: Blood Oxygen Level Dependent (BOLD) imaging and perfusion-based imaging.
- BOLD imaging sequences assess the hemodynamic response related to neural activity, providing insights into brain function during cognitive tasks.
Biomarkers After TBI
- Several biomarkers have been researched for their presence in serum after TBI, indicating cellular response and injury severity.
- Understanding these biomarkers aids in developing diagnostic and prognostic tools for clinical application.
Importance of Advanced Neuroimaging
- Advanced neuroimaging testing is crucial for accurate TBI diagnosis and management, enabling tailored treatment strategies.
- Neuroimaging results assist in understanding the extent of injury, planning rehabilitation, and predicting patient outcomes.
TBI Diagnostic Testing Classification
- TBI diagnostic testing can be categorized based on the techniques used, including structural imaging (CT, MRI) and functional imaging (fMRI, ASL).
