Site of flow acquisition and venous sinus measurement in a control patient. a An MRA of a 4.7 year old male with seizures who had a normal MRI. The while line indicates the level of the flow quantification acquisition. The acquisition crosses both carotid and basilar arteries at the skull base. b An MRV of the same child with while lines showing the sites of the cross-sectional measurements. From superior to inferior these are the sagittal sinus, transverse sinuses, vertical portion of the sigmoid sinuses and the horizontal portion of the sigmoid sinuses. c The cross-sectional image of the sagittal sinus which is triangular. d The cross-sectional image of the right transverse sinus which is triangular. e The cross-sectional image of the left vertical sigmoid sinus which is oval. f The cross-sectional image of the horizontal portion of the sigmoid sinus which is oval
