This figure shows the scan of a 58-year-old male patient (subject 11) with a complex occipital dural AVF (Cognard type IIb) fed by branches of both external carotid and vertebral arteries.It highlights the advantages of venous saturation pulses in 7 Tesla TOF MRA. The exact location of the fistulous point (arrow in magnified image section) is depicted by mixing hyperintense unsaturated arterial blood with hypointense saturated venous blood in the superior sagittal sinus.
