Evaluation of corpus callosum lesions following intracranial tumors by using magnetic resonance tractography and diffusion tensor imaging
Keywords:corpus callosum, commissural fibers, astrocytomas, metastasis, MR tractography, diffusion tensor imaging
Introduction. The results of the evaluation of data MR tractography and DTI in patients with brain tumors that spread to the area of the corpus callosum (CC) were presented.
Materials and methods. MRI was performed with the construction of MR tractography and evaluation data DTI in 23 patients with brain tumors that spread to the area of the CC.
Results. According to MR tractography and DTI astrocytoma Gr.I-II cause any destruction of commissural fibers CC (8.7% of cases) or displacement and ousting its fibers (13%). Astrocytoma Gr.III-IV — complete or partial destruction of commissural fibers CC (65.3%). Metastases — displacement, ousting commissural fibers MT without violating their integrity (13%).
Conclusions. MR tractography based DTI allows us to estimate the degree of damage commissural fibers of the CC with brain tumors according to the location.
