title: MR angiography artifact due to metal joint of ventriculoperitoneal shunt mimicking severe carotid stenosis.
abstract: An artifact due to the metal joint of a ventriculoperitoneal shunt resulted in a diagnosis of severe internal carotid artery stenosis at magnetic resonance angiography. Conventional x-ray angiography showed the presence of the metal joint and revealed that the artery was not stenotic.
