We present here two patients that had an aberrant right subclavian artery and an anomalous origin of the right vertebral artery from the right common carotid artery. We review the previous literature and discuss herein the embryologic mechanism and clinical implications of this variation.
OBJECTIVE We have used diffusion tensor tractography (DTT) for the evaluation of the somatotopic organization of corticospinal tracts (CSTs) in the posterior limb of the internal capsule (PLIC) and cerebral peduncle (CP). MATERIALS AND METHODS We imaged the brains of nine healthy right-handed subjects. We used a spin-echo echo-planar imaging (EPI)(More)
Despite denial as a disease entity, carotidynia had shown relatively concordant imaging finding as an inflammatory process surrounding the carotid bifurcation area. We report serial computed tomography (CT) images of a case with carotidynia that showed the layered thickening of the carotid wall with self-limiting disease course.
BACKGROUND We evaluated the feasibility of black-blood double inversion recovery magnetic resonance imaging (BBDIR) and CT imaging (CTI) for depiction of IAPs. METHODS We performed BBDIR on 20 control subjects and 13 patients with acute ischemic stroke. We measured the thickness of the normal vessel wall in control subjects and the maximal and minimal(More)
