These images are from an MRV (magnetic resonance venogram). The principle is similar to an MRA, except the image acquisition parameters are set to highlight venous anatomy. The image on the left represents an AP view, and the image on the right represents a lateral view.

1. superior sagittal sinus

2. transverse sinus

3. sigmoid sinus

4. confluence of sinuses (torcula)

5. straight sinus
