Understanding Angiography of brain
Digital Subtraction Angiography provides detailed visualization of brain. Contrast material highlights vascular structures and improves tissue differentiation. The procedure uses controlled radiation to create precise images with excellent anatomical detail.
Clinical Indications
This evaluation helps detect arterial blockages, identify aneurysms, assess blood flow patterns, and guide vascular interventions.
What to Expect
The procedure typically takes 10 minutes. You may experience a brief warm sensation as contrast is administered. The examination is painless and non-invasive.
How to read the report
- Results reviewed by board-certified radiologist.
- Report transmitted to referring physician.
