Stewart, We tried to scan pt. for Temporal Arteritis and had Many patients
with a positive biopsy and no temperal artery "halo",  I am not sure if any
one out there has any protocols other than obvious areas of narrowing within
the Temporal artery ...we use our "entos" ATL scanhead.  Also....the
Temporal artery is extracranial....not necessarily near any temporal
window...excess power would not be a problem unless you were using TCD power
settings.
