Abstract Objective: To investigate the MRI and MSCT characteristics of persistent falcine sinus, in order to improve the understanding and diagnosis of it． Methods: Clinical, MRI and MSCT data were collected from 17 patients with persistent falcine sinus confirmed by MRI and MSCT from January 2005 to July 2014． Results: MRI cerebral conventional examination was performed in 9 cases, and T2WI sagittal view showed an enlargement vascular flow void signal arising from the great cerebral vein and draining into the superior sagittal sinus in its middle and posterior third part. Magnetic resonance venous imaging(MRV) clearly showed the great cerebral vein draining into the superior sagittal sinus through the opening falcine sinus in 2 cases． Enhanced T1WI also clearly showed the superior sagittal sinus connected with the cisternae venae magnae cerebri by an enhanced blood vessel in 1 case． Five patients underwent CTA, and falcine sinuses were seen as ribbon or yardstick-like vascular structures between the vein of Galen or straight sinus and the posterior third part of the superior sagittal sinus. Conclusion: MRI and MSCT imaging of persistent falcine sinus is characteristic． Conventional MRI combined with MRV, enhanced MRI and MSCT can show the appearance more clearly, position of the persistent falcine sinus and its relationship with surrounding structures, contributing a lot to its comprehensive evaluation．
