What imaging technique is used to visualize blood vessels and check for stenosis?

• A. X-ray
• B. Magnetic resonance imaging (MRI)
• C. Angiography
• D. Computed tomography (CT)

Answer: (C)

Angiography is the correct choice for visualizing blood vessels and checking for stenosis. This imaging technique specifically involves the use of a contrast dye that is injected into the blood vessels, typically under fluoroscopic guidance. This allows for detailed imaging of the vascular structures, enabling the identification of obstructions or narrowing (stenosis) in the vessel. The detailed images produced can help facilitate diagnoses and guide treatment plans for various vascular conditions. While X-rays, MRI, and CT scans can also be utilized in the assessment of vascular issues, they are not as specific or effective as angiography for directly visualizing blood vessel lumen and detecting stenosis. X-rays do not provide sufficient detail for blood vessels without the use of contrast, while MRI and CT generally offer less direct visualization of vascular structures compared to the targeted approach of angiography. Thus, angiography stands out as the most appropriate imaging technique for this purpose.
