Aortography Chest and Abdomen Catheter-based aortography is considered the reference standard for the diagnosis of congenital aortic diseases [10]. Aortography provides information regarding flow and allows hemodynamic measurements to be taken; however, several noninvasive studies can provide similar information. As such, the role of aortography in diagnosing aortic diseases is decreasing as the sensitivity of other noninvasive modalities, such as transthoracic echocardiography (TTE), CTA, and MR angiography (MRA) improves [11-18]. Aortography is now most commonly performed when an intervention is planned. CT Chest and Abdomen There is no relevant literature available to examine the use of CT chest and abdomen with intravenous (IV) contrast alone in the management of congenital aortic disease.
