      Using spinal MR imaging to dichotomize patients with spontaneous intracranial hypotensioninto spinal longitudinal extradural CSF collection positive and negative populations accurately determines the nature of their underlying CSF leak (mechanical dural tear versus CSF venous fistula or nerve root sleeve leak), correctly predicts in whom autologous nondirected and directed epidural blood patch may work and in whom it will fail, and finally prescribes the positioning (prone versus decubitus) for subsequent dynamic myelography providing the most efficient pathway to definitive leak localization and repair. Using this systematic approach, the authors have been able to identify the exact site of CSF leakage in 27 (87%) of 31 consecutive patients referred to their institution with MR imaging evidence of SIH.

      Gadolinium-Enhanced Susceptibility-Weighted Imaging in Multiple Sclerosis: Optimizing the Recognition of Active Plaques for Different MR Imaging Sequences

      The authors analyzed the accuracy of gadolinium SWI for detecting the imaging evidence of active inflammation on MS plaques when a BBB dysfunction was demonstrated by a focal gadolinium-enhanced lesion and compared this technique with gadolinium-enhanced T1 spin-echo and T1 spin-echo with magnetization transfer contrast sequences. Differences in BBB dysfunction were evident in the 103 patients among gadolinium SWI, gadolinium T1 spin-echo, and gadolinium T1 magnetization transfer contrast. Gadolinium T1 magnetization transfer contrast demonstrated the highest number of active demyelinating plaques. Gadolinium SWI was highly correlated with gadolinium T1 magnetization transfer contrast in depicting acute demyelinating plaques and these techniques provided better performance compared with gadolinium T1 spin-echo.
