Which diagnostic test is used to visualize the vascular system after injecting contrast dye and taking X-ray pictures?

• A. CT (Compound Tomography)
• B. MRI
• C. X-ray
• D. Angiogram

Answer: (D)

Angiography is the imaging study designed to visualize blood vessels by injecting a radiopaque contrast dye and taking X-ray images. The contrast highlights arteries and veins, letting you see blockages, aneurysms, or abnormal vessels. It’s usually performed under fluoroscopy, so clinicians can watch how the dye fills the vessels in real time. Plain X-ray doesn’t show vessels clearly on its own, and MRI or CT image vessels using different techniques (like MR or CT angiography), but the classic test described—visualizing the vascular system after contrast with X-ray imaging—fits an angiogram.
