AI Article Synopsis
- Assessing cerebral vasculopathies is complex and depends on understanding various imaging methods' strengths and weaknesses.
- Techniques include bolus-based CT and MR angiography, which need precise timing for contrast enhancement, and non-contrast MRA, which avoids contrast but may have less detail.
- Digital subtraction angiography is the most reliable but invasive, whereas VW-MRI is a non-invasive option for evaluating vessel wall issues; traditional brain MRI is good for detecting vasculitis but offers non-specific results.
Article Abstract
Assessment of cerebral vasculopathies is challenging and requires understanding the utility of different imaging methods. Various techniques are available to image the vessel lumen, each with unique advantages and disadvantages. Bolus-based CT and MR angiography requires careful timing of a contrast bolus to provide optimal luminal enhancement. Non-contrast MRA techniques do not require a contrast agent and can provide images with little venous contamination. Digital subtraction angiography remains the gold standard but is invasive, while VW-MRI provides a non-invasive way of assessing vessel wall pathology. Conventional brain MRI has high sensitivity in the diagnosis of vasculitis but findings are nonspecific.
