Case: Aortic Aneurysm with Complex Endovascular Repair

posted by Carlo Nicola De Cecco, M.D., PhD | Jul 1, 2016
Carlo Nicola De Cecco, M.D., PhD

In this case, 70 kV was applied which resulted in an excellent intravascular contrast enhancement with only 50 mL contrast medium and a significant effective dose reduction to 3.9 mSv. To further reduce the increased image noise, associated with the lower tube voltage setting, images were reconstructed using ADMIRE … Read more
