What is Digital Subtraction Angiography (DSA)?
Digital Subtraction Angiography (DSA) is a fluoroscopic method used to evidently visualize blood vessels in a bony or complex soft tissue environment in interventional radiology. These images are captured by computerized X-ray devices. A specific dye or contrast medium is generally applied to create it simpler to see the blood in the legs, heart or other organ during the test. The concept behind DSA is to obtain a static image in the first phase of the procedure and subtract it from the following vibrant image flow.
