From: Spontaneous intracranial arterial dissection in the young: diagnosis by CT angiography
Dynamic computed tomographic scans with maximum intensity projection (MIP) images in the coronal (a) and parasagittal planes (b, c) revealing diminished caliber of the intracranial portions of the left internal carotid artery (arrow). The contralateral right internal carotid artery displays normal caliber (arrowhead).
