Objective: to analyze the contribution of diffusion MR tractography imaging to determine the value of the integrity and function of the great tracts of fibers in the white matter in healthy volunteers and patients. Material and method: diffusion MR tractography imaging was analyzed using with a 1.5-T , PHILIPS Intera Archieva, 7 min. of scans, TR-6.707, TE-89, 1.44 x 1.44 x 300 mm VOXEL, 0.3 GAP, 230 mm FOV, 3 mm thick slices ,acquisition 4, 112 x 116 MATRIX, EPI tec., Single Shot 16 directions in 10 healthy volunteers and 3 patients, one of them with angioma malformation, another one with oligodendroglioma, and the last case with diffuse axonal injury. Results: the tracts in the white matter were observed in all healthy volunteers. Regarding to patients, we observed displacement of fiber in one of them, displacement and non-infiltration in another one, and partial damage of the tracts in the last one. Conclusion: diffusion MR tractography imaging is of great value for observed the fiber and beam elocuent, including their functional state.
