A–D, Diffuse sinus thrombosis (arrows, arrowheads) in a 37-year-old woman with a history of abruption of placenta and diabetes insipidus. The diagnosis of thrombosis may be possible from the sagittal MIP image of 2D-TOF MR venography (25/9/1, flip angle = 30°) (A) and by the indirect finding of lack of visualization of the affected sinuses. With 3D contrast-enhanced MP-RAGE (13.5/7/1, TI = 300, flip angle = 15°), however, the reconstructed sagittal and source axial images (B and C) show the extent and size of the low signal thrombosis (arrows) as well as the patency of the affected sinuses, which is confirmed on DSA image (D)
