DYNA EMBOLIZATION - Pilot Study of IV Dyna CT and CBV Imaging Techniques

"The scan requires that the patient lie still on a hard surface for about 5-10 minutes. Before the scan, they will have a special fluid called contrast dye injected through the IV in their arm. This contrast dye helps to see the blood in the arteries using x-ray pictures.~After the IV dyna CBV is completed, they will have their routine conventional angiography to evaluate the lesion for embolizable arteries as part of routine clinical care. If the patient undergoes embolization of the lesion (as part of the standard of care), a post embolization Dyna CBV will be performed."
