Digital Subtraction Angiography (DSA)

Digital Subtraction Angiography (DSA) is an imaging technique used to visualize blood vessels. It involves injecting a special dye (contrast agent) into the bloodstream, then taking X-ray images. By using digital technology, the images taken before and after the dye is added are digitally "subtracted," removing bones and surrounding tissues from view. This process highlights the blood vessels clearly, helping doctors diagnose conditions like blockages, aneurysms, or other vascular issues. DSA provides detailed, real-time images that are essential for accurate assessment and planning of treatment options.
