The purpose of this study was to assess the usefulness of three-dimensional (3D) gadolinium-enhanced magnetic resonance (MR) angiography for evaluation of the intracranial venous system. ⋯ Three-dimensional gadolinium-enhanced MR angiography is noninvasive and very useful for imaging of the intracranial venous system. It can replace 2D TOF MR venography not only because of its short examination time but because it better demonstrates intracranial venous structures. For evaluation of the SSS, lateral sinus, sigmoid sinus and straight sinus in particular, conventional catheter angiography seems to be unnecessary.
