title: Magnetic resonance imaging in internal carotid artery agenesis with computed tomography and angiographic correlation--case reports.
abstract: The authors present two cases of agenesis of the internal carotid artery (ICA) discovered incidentally on magnetic resonance imaging and confirmed on computed tomography, magnetic resonance angiography, and conventional angiography. They also propose a clinical algorithm for the workup of patients with suspected absence of the ICA.
