The degree of demyelination and signal disruption can be quantified by measuring the functional anisotropy (FA) and mean diffusivity (MD) of white matter tracts (WMTs) via diffusion tensor imaging (DTI). In this study, we analyzed the correlation between clinical variables evaluating LUTS (including urodynamics parameters and validated questionnaires) with both FA and MD values in a cohort of female MS patients. METHODS: Twenty-eight MS women with LUTS were enrolled in this prospective study. Urodynamics and validated questionnaires including the Urinary Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) were collected. DTI images were acquired (32 directions, one B0 image) for each subject using the standard MRI pulse sequence available on the Philips 3 Tesla Ingenia scanner. The AFNI software package was used to automatically align clinical DTI images onto the ICMB DTI81 atlas to extract the FA and MD values of 50 tracts for each subject. Pearson’s correlation was performed between FA and MD values versus each clinical variable for all 50 tracts. Any WMTs with a p-value less than 0.05 on the Pearson’s correlation with FA or MD in at least one of the clinical variables was considered a statistically significant correlation. A positive correlation coefficient (R) for MD and negative correlation for FA were noted as signs of WMT demyelination contributing directly to clinical symptoms whereas a negative correlation for MD and positive correlation for FA were noted to indicate compensatory strengthening of the WMT in an effort to maintain continence in the presence of MS. Only WMTs with |R| >0.3 were reported. RESULTS: Five WMTs (ML-L, CP-R, SS-R, UNC-L, and SFO-R) showed statistically significant demyelination in correlation to symptoms, whereas three WMTs (IFO-R, PCR-R, and CGH-L) displayed statistically significant compensatory strengthening (Table 1). CONCLUSIONS: The ability to correlate changes in WMT signaling to clinical symptoms strengthens our understanding of the demyelination that leads to LUTS in female MS patients and can enable the development of targeted therapies for patients early in the disease course.
