脑肿瘤作为一种常见的中枢神经系统疾病,其早期诊断和精确治疗对于提高患者生存质量和延长生存期至关重要.然而,传统的MRI技术在分辨率和对比度上存在局限,导致对脑肿瘤的识别和边界划分存在一定困难.7 T MRI技术能够清晰显示脑肿瘤的微观结构,从而更准确地识别肿瘤类型和分级.此外,7 T MRI在动态监测肿瘤生长、评估肿瘤微环境以及指导手术切除方面也展现出巨大潜力.本文综述了7 T MRI在脑肿瘤研究中的应用进展,并探讨了7 T MRI技术在脑肿瘤研究中面临的挑战和未来的发展方向,旨在为临床医生和研究人员提供参考和指导.
Abstract
Brain tumors,as prevalent central nervous system malignancies,require early and accurate diagnosis for improving patient survival rates and quality of life.However,traditional MRI techniques face limitations in resolution and contrast,posing challenges in the identification and delineation of brain tumors.7 T MRI technology offers superior visualization of the tumor's microstructure,enabling more precise tumor typing and grading.Moreover,7 T MRI demonstrates significant potential in dynamically monitoring tumor growth,assessing the tumor microenvironment,and guiding surgical resection.This review summarizes the advancements in the application of 7 T magnetic resonance imaging in brain tumor research and discusses the challenges and future directions of 7 T MRI technology in brain tumor studies,aiming to provide insights and guidance for clinicians and researchers.
