What is the Digital Cardiac Angiography?

The Digital Cardiac Angiography (DCA) is also sometimes known as the Digital Subtraction Angiography(DSA). It is a medical test, a modified form of computer imaging that records pictures of the major blood vessels to the heart or brain. It lets a doctor know if there are any blockages in your blood vessels, how severe they are, and what can be done about them. In this test, a dye is injected into a vein in the arm, and an X-ray machine quickly takes a series of pictures of the chest or head and neck.From one of our reader’s experience, it is not a painful procedure, but a bit unpleasant if you are afraid of needles.
