Fig 1. Coronal (A) and sagittal (B) views from maximum intensity projection (MIP) of 2D TOF MRV demonstrate signal intensity void in the posterior aspect of superior sagittal sinus and medial aspect of transverse sinuses. On the coronal (C) and sagittal (D) reformatted images of the CTV, there is normal flow seen in the superior sagittal sinus and transverse sinuses, which confirms that the signal intensity void seen in the superior sagittal and transverse sinuses is artifactual.
