A–E, Postoperative sinus thrombosis (arrows) in a 62-year-old man. The coronal source and MIP images of 2D-TOF MR venography (25/9/1, flip angle = 30°) (A and B) show no flow signals in the left transverse and sigmoid sinuses, which may be difficult to differentiate from hypoplasia of the sinuses (see fig 5). The reconstructed coronal and source axial images (C and D) from a 3D contrast-enhanced MP-RAGE sequence (13.5/7/1, TI = 300, flip angle = 15°) clearly show the thrombosis in the left transverse and sigmoid sinuses, which is confirmed on the DSA image (E)
