Perfusion Imaging
4
Feb

Overview

Perfusion imaging evaluates blood flow volume and transit time in tissues. Modalities include CT MRI and nuclear methods. Perfusion provides functional information for stroke tumor and cardiac assessment.

Brain Perfusion

CT and MR perfusion identify ischemic penumbra in acute stroke. Perfusion maps guide reperfusion therapy and prognosis. Standardized thresholds aid clinical decision making.

Tumor Perfusion

Perfusion imaging assesses tumor vascularity and response to therapy. Changes in perfusion metrics can indicate treatment effect. It complements anatomic and metabolic imaging in oncology.

Cardiac Perfusion

Myocardial perfusion imaging evaluates ischemia and viability. PET SPECT and MRI provide perfusion assessment depending on clinical needs. Quantitative perfusion supports risk stratification and management.

Head and Neck Imaging

Overview

Head and neck imaging uses CT MRI and ultrasound depending on the indication. It evaluates tumors infections and trauma. Detailed anatomic imaging guides surgical planning.

Oncologic Imaging

Imaging stages head and neck cancers and assesses treatment response. PET CT is useful for metabolic assessment. MRI provides soft tissue detail for surgical planning.

Airway and Swallowing

Fluoroscopy and video swallow studies assess swallowing function. Imaging evaluates airway patency and structural abnormalities. Findings guide therapy and surgical decisions.

Vascular Considerations

CT angiography and MR angiography assess vascular lesions and fistulas. Vascular imaging is important in trauma and tumor planning. Endovascular options may be guided by imaging findings.

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.

Perfusion Imaging CT MR PET
4
Feb

Overview

Perfusion imaging measures blood flow blood volume and mean transit time using CT MRI or PET to assess ischemia and tumor perfusion.

Technique

Dynamic contrast bolus tracking and deconvolution algorithms produce quantitative perfusion maps. Acquisition timing is critical.

Clinical Uses

Acute stroke core and penumbra assessment tumor perfusion for grading and therapy response and myocardial perfusion.

Limitations and Safety

Contrast use and radiation for CT. Standardization across platforms is challenging.
