Feb

Overview

Diffusion imaging measures water mobility to infer tissue microstructure. It is sensitive to acute ischemia and white matter integrity. Diffusion techniques include DWI and DTI among others.

Acute Stroke

Diffusion weighted imaging detects acute ischemic injury within minutes of onset. It guides reperfusion therapy decisions and prognosis. ADC maps help differentiate cytotoxic from vasogenic edema.

White Matter Tracts

Diffusion tensor imaging maps white matter tracts and connectivity. It aids in surgical planning and research on neurodevelopment and degeneration. Tractography supports preservation of critical pathways.

Advanced Methods

High angular resolution and multi shell acquisitions improve microstructural modeling. Quantitative diffusion metrics provide biomarkers for disease. Ongoing work refines acquisition and analysis standards.

Head CT

Overview

Head CT is rapid and widely available for acute neurologic assessment. It detects hemorrhage fractures and mass effect. CT is the first line tool in many emergency settings.

Trauma and Hemorrhage

CT identifies acute intracranial hemorrhage and skull fractures. Rapid detection guides neurosurgical and critical care interventions. Repeat imaging monitors evolution of findings.

Chronic Disease

CT evaluates chronic sinus disease calcifications and bone pathology. It complements MRI for certain indications and surgical planning. Non contrast and contrast enhanced protocols are used as appropriate.

Limitations and Complementary Imaging

CT has limited soft tissue contrast compared with MRI. MRI provides superior evaluation of brain parenchyma and posterior fossa. Choice of modality depends on clinical question and timing.

Neuroimaging

Feb

Overview

Neuroimaging includes CT MRI and nuclear techniques for brain and spine. It evaluates stroke tumors infection and degenerative disease. Advanced imaging provides functional and metabolic information.

Stroke Imaging

CT and MRI protocols rapidly assess ischemic and hemorrhagic stroke. Perfusion imaging identifies salvageable tissue. Rapid imaging guides reperfusion therapy decisions.

Tumor Evaluation

MRI provides detailed tumor characterization and extent. Advanced sequences assess cellularity vascularity and metabolism. Imaging guides biopsy and treatment planning.

Functional Imaging

Functional MRI and PET assess brain activity and metabolism. These techniques support presurgical mapping and research. They provide insight into neurologic disorders and recovery.

CT Perfusion Stroke

Feb

Overview

CT perfusion assesses cerebral blood flow and volume to identify salvageable brain tissue. It complements non contrast CT and CT angiography in acute stroke evaluation. Perfusion maps guide reperfusion therapy decisions.

Acquisition and Processing

Rapid acquisition and automated processing produce perfusion maps for clinical use. Standardized thresholds help identify ischemic core and penumbra. Timely imaging is critical for treatment eligibility.

Clinical Impact

Perfusion imaging expands treatment windows for selected patients by identifying viable tissue. It supports decision making for thrombectomy and thrombolysis. Integration with clinical assessment optimizes outcomes.

Limitations

Perfusion results can vary with acquisition parameters and post processing algorithms. Artifacts and patient motion may affect interpretation. Multidisciplinary protocols ensure appropriate use and interpretation.
