Indication Dual Energy CTA Aorta

posted by Marco Das, M.D. | Mar 28, 2008

Aortic aneurisms are a common pathology, with the potential risk of rupture. To characterize the aneurysm and for differential diagnosis CTA is performed. Dual Energy improves the aortic examination by higher image quality of CT angiography (CTA). MSCT – first line modality for aortic pathologies in the ER In imaging of the … Read more
