The principle of oscillating gradient spin echo in diffusion magnetic resonance imaging and its application in gliomas
摘要
Abstract
Gliomas are the most common primary central nervous system tumors in adults with high mortality rate and strong invasiveness. The tumor grading and genetic phenotype heterogeneity of gliomas will affect the formulation of treatment plans and prognosis inference. Post-treatment efficacy evaluation and early diagnosis of tumor recurrence can help improve patient survival. Diffusion magnetic resonance imaging based on oscillatory gradient spin echo (OGSE) is a novel diffusion MRI technique that has broad application prospects in the imaging diagnosis of gliomas by detecting microstructure features, such as cell diameter, cell density, intracellular and extracellular volume fraction. This paper reviewed the technical principles of OGSE imaging, research progress in classification, prediction of molecular type, response evaluation and differential diagnosis of brain glioma and limitations of OGSE imaging applications, providing a new perspective for preoperative diagnosis and postoperative evaluation of glioblastoma.关键词
