Consecutive axial CE-MRA images from the cranial-to-caudal direction depict the CNIX and the CNX/XI complex within the JF. A, The most cranial section is located on the level of the right supCNIX and the left infCNIX (crossed arrow). Note that in this case, no circumscript thickening of the nerve is identifiable. Thin white arrows indicate the inferior petrosal sinus; 1, the ICA; 2, the sigmoid sinus. B, Section at the level of the supCNIX (thick arrows). Crossed arrows indicate CNIX within the JF; thin white arrows, the inferior petrosal sinus; 1, the ICA; 2, the sigmoid sinus. Note that the right sigmoid part (2`) is significantly larger than the left one (2) in this case. J. Linn et al. AJNR Am J Neuroradiol 2009;30:34-41 ©2009 by American Society of Neuroradiology
