Measurement of stenoses located in the middle cerebral, intracranial vertebral, or basilar arteries. If there is a focal stenosis that does not involve the origin of index artery, then the widest, parallel, normal, proximal, nontortuous segment is chosen to measure the normal reference diameter (D_normal). If the index artery is stenotic at its origin, but its feeding artery is normal, the widest, normal, nontortuous segment of the feeding artery is chosen to measure D_normal. If the index artery is diseased in its entire length, the most distal, normal, parallel, nontortuous segment of the artery is chosen to measure D_normal.

Measurement of stenoses in the intracranial carotid artery. For the precavernous, cavernous, and postcavernous intracranial carotid artery, the widest, nontortuous, normal portion of the petrous carotid artery is chosen to measure the normal reference diameter (D_normal). If the entire petrous portion of the carotid artery is diseased, the most distal, parallel, normal part of the extracranial internal carotid artery is chosen to measure D_normal.
