MR-tractography method: modern features of visualization and use in neurosurgical practice
Keywords:gliomas, schwannomas, meningiomas, metastases, cavernous angiomas, MR-tractography, conductive paths
Introduction. Modern features of MR-tractography in neuroimaging and at neurosurgical intervention planning at different brain tumors are presented.
The purpose. To study MR-tractography facilities for use in neurosurgical practice by assessing the state of pathways at different brain tumors and their impact on the trajectory of main pathways.
Materials and methods. MRI with MR-tractography were performed 143 patients with different brain tumors, 82 of them have been operated with further histological verification.
Results. According to MR-tractography data gliomas were characterized by infiltration, destruction of conductive fibers and main pathways in the area of tumor growth, paths offset due to tumor’s volume effect. Nodal tumors (schwannoma, meningioma, solitary metastasis, cystic formation, cavernous angioma) were characterized by offset of conductive fibers and the main paths, without tampering. In case of tumor’s significant volume impact on brain tissue paths thinning was observed due to compression of their fibers. Surgical tactics at volume formations, particularly at gliomas, was determined by degree of main paths lesion.
Conclusions. MR-tractography — an advanced method to assess conductive paths lesion degree at brain tumors, it’s data are used in modern neurosurgery.
