Fig 1. Sagittal (A) and coronal (B, C) sections of MIP reformations in a 22-year-old woman (patient 11) demonstrate the normal venous anatomy: superior sagittal sinus (thin arrow), the inferior sagittal sinus (arrowheads), the straight sinus (thick arrow), and the transverse sinuses (curved arrows). No venous pathologic condition was present in this patient. The MDCTA was performed on a 64-row-detector system.
