A). Coronal free-breathing REACT MIP image reveals incidental focal stenosis at the right proximal internal carotid artery (arrow). No vascular stenosis or extrinsic mass effect is identified at the thoracic outlet. Note the excellent depiction of the intercostal arteries. B). Subsequent CTA performed two weeks later shows a short segment of moderate stenosis of the right internal carotid artery due to an atherosclerotic plaque, correlating with findings on earlier REACT MRA.
