[Abstract] Objectives: Motion of the cerebrospinal fluid (CSF) in aqueduct of sylvius was examined in volunteers and a number of patients with abnormalities of the CSF circulation with MRI in phase contrast cine mode (Mm cine PC).Materials and Methods: Control group 30 cases hydrocephalus group 16 cases on a Philips Achieva 3.0 T X-series MRI unit were displayed. Quantitative evaluation of CSF flow via phase reconstruction permits a more precise mapping of the intracranial and intraspinal flow patterns is more sensitive in detecting fluid motion and allows calculation of CSF velocity and flow volume.Results: Aqueduct cerebrospinal fluid of control group is associated with cardiac pulsation the flow type of control group is bi-directional flat rhythmic flow. In control group ,the cerebrospinal fluid flow curve was the smooth inverted u" type ,and in hydrocephalus group the curve was wave type. The average CSF flow of the head and foot side in the control group were (0.0311+0.0201) ml/s and (0.0366+0.0196) ml/s, the velocities were (4.027+1.174) cm/s, (4.107+1.433) cm/s, respectively. In hydrocephalus group, the average CSF flow of the head and foot side were (0.0070+0.0069) ml/s and (0.0078+0.0044) ml/s, the velocities were (0.550+0.327) cm/s, (0.606+0.599) cm/s respectively. The comparisons of the average flow velocity between two groups have statistics meaning (P<0.05).Conclusions: Cine PC MRI, is capable of demonstrating both normal and abnormal intracranial and intraspinal CSF flow. Such a study can be easily added as an extra pulse sequence at the end of a routinely acquked MR exam.
