| what machines does angio uses |
uses constrast material & CT, MRI,X-ray to produce pictures of major blood vessels throughout the blood. |

after the contrast is injected through the catheter & reaches the blood vessels being studied-several x-rays are taken |
| how is the incision site closed |
by placing pressure on the area for approx.10 minutes. |
| when is the IV removed |
after the radiologist determines that all the necessary images have been obtained |
