摘要We used MRI to examine 38 healthy females and 38 female patients with empty sella syndrome. Cerebrospinal fluid flow was examined in six regions of interest, including the anterior clinoid processes, posterior clinoid processes, and 1.0 mm, -1.0 mm, 2.0 mm, -2.0 mm from the midpoint of the line between the anterior and posterior clinoid processes. The results revealed no significant differences in cerebrospinal fluid flow velocity and discharge in a single cardiac cycle, or indicators of cardiac cycles in the control group, indicating that the cerebrospinal fluid flow was relatively steady in the saddle area of the normal brain. In the empty sella syndrome group, cerebrospinal fluid hernia into the saddle area triggered a fluctuation of the anterior and posterior clinoid processes in the saddle area, while the flow in other regions in the saddle area was relatively steady; this resulted in significant differences in cerebrospinal fluid flow velocity and discharge, as well as the cardiac cycle.
