WebApr 13, 2024 · All patients were preoperatively evaluated by phase contrast cine-MRI to study the CSF flow and enhanced MRI to assess possible arachnoiditis. A complete spinal cord MRI was also obtained. There were 84 patients (85.7%) with CM Type 1 (CM-1), while CM Type 1.5 (CM-1.5) was identified in 14 patients (14.2%). WebSep 18, 2024 · PCC-MRI is a non-invasive method used to study CSF flow dynamics in IIH. The most specific CSF flowmetry parameter to diagnose IIH is mean flow (MF), and it was significantly higher in first discovered IIH group than other IIH groups. So we concluded that PCC-MRI can be used as non-invasive technique for diagnosis of IIH.
