DIGITAL ANGIOGRAPHY

To create a blood or artery X-ray, also called digital angiography, iodine is injected into the veins and a digitized image is created. Then, a second image is established of only the parts of the X-rayed section without iodine. The first image is subtracted then a final image is produced containing both the first and second images together. Lastly, the results are printed. The doctor or surgeon then compares the results of the angiography to a perfect angiography structure to see if there are any malfunctions.
