How is internal carotid agenesis diagnosed?

Internal carotid agenesis is diagnosed when the absence of the internal carotid artery is noted on tests used to visualize the blood vessels and surrounding bones such as angiography, computed tomography scanning (CT scan), and magnetic resonance imaging (MRI).[1] [2]  Once internal carotid agenesis is diagnosed, these tests are done periodically to monitor the other blood vessels and check for aneurysms.[1]
