Application of diffusion tensor imaging to brain tumors radiotherapy / 中华放射医学与防护杂志

ABSTRACT

Diffusion tensor imaging (DTI) uses the diffusion motion of water molecules to describe the spatial structure of brain.DTI,which can obtain the infiltration of brain tumors into normal physiological structures,makes the diagnosis of diseases change from macroscopic to microscopic,from morphology to both morphology and metabolism,bringing new opportunities for the diagnosis and treatment of brain tumors.In this review,we outlined the theoretical basis and current technical limitations of DTI,and comprehensively discussed its research values in brain tumors radiotherapy treatment and its prognostic value.We believe that DTI can provide important imaging information for radiotherapy planning of brain tumors.
