Selection and Interpretation of Diagnostic Imaging Tests for Evaluating Cerebrovascular Lesions

Emerging Imaging Techniques and Innovations in Cerebrovascular Diagnosis

Cerebrovascular lesions, including ischemic and hemorrhagic stroke, require precise imaging for accurate diagnosis and management. Advances in radiodiagnosis have led to the development of high-resolution and functional imaging techniques that enhance diagnostic accuracy.

Standard Imaging Modalities

• Computed Tomography (CT): Rapid assessment of acute stroke and hemorrhage.
• Magnetic Resonance Imaging (MRI): Detailed imaging for ischemia and vascular abnormalities.
• Ultrasound (Carotid Doppler): Evaluation of extracranial arteries.

Emerging Techniques

• CT Perfusion Imaging: Assesses cerebral blood flow and infarct core.
• MR Angiography: Provides non-invasive vascular mapping.
• Artificial Intelligence-assisted Imaging: Enhances stroke detection and classification.

Interpretation Considerations

Clinicians must consider patient history, symptoms, and imaging findings for optimal cerebrovascular lesion evaluation. Integration of advanced imaging modalities improves diagnostic precision and treatment planning.
