Cavernous Sinus and Inferior Petrosal Sinus Flow Signal on Three-Dimensional Time-of-Flight MR Angiography

摘要

BACKGROUND AND PURPOSE: Venous flow signal in the cavernous sinus and inferior petrosal sinus has been shown on MR angiograms in patients with carotid cavernous fistula (CCF). We, however, identified flow signal in some patients without symptoms and signs of CCF. This review was performed to determine the frequency of such normal venous flow depiction at MR angiography.
