The effect of a gadolinium-based contrast agent on diffusion tensor imaging

Popis výsledku v původním jazyce

Objective: The aim of this study was to investigate in detail the effect of gadolinium contrast on diffusion tensor imaging scans. As the present literature offers conflicting results, we have included a large selection of indices in the analysis. Materials and methods: Sixteen patients harboring an intra-axial contrast enhancing brain tumor were included in this study. Two diffusion tensor imaging scans were performed-one natively, and the second following a gadolinium contrast agent application. Mapsof the invariant indices fractional anisotropy (FA), linear, planar, and spherical indices, trace, eigenvalues lambda(1), lambda(2), lambda(3) as well as of the components of the diffusion tensor matrix Dxx, Dyy, Dzz, Dxy, Dxz and Dyz were co-registeredand compared statistically with matching ROI pairs in the contrast enhancing areas, peritumoral edema and the normal appearing white matter. Results: We have observed a significant increase in the FA and disproportional decrease of the ei
