摘 要
磁共振成像（MRI）作为现代医学影像技术的重要组成部分，在神经系统疾病的诊断中具有不可替代的优势。本研究旨在系统分析MRI在神经疾病诊断中的应用价值及其局限性，通过回顾性分析120例神经系统疾病患者的MRI检查数据，并结合临床表现与病理结果进行综合评估。研究表明，MRI凭借其高分辨率和多参数成像能力，能够清晰显示脑组织结构及病变特征，对脑肿瘤、脑卒中、脱髓鞘疾病等多种疾病的早期诊断和精准定位具有显著优势。此外，功能性磁共振成像（fMRI）和弥散张量成像（DTI）等先进技术的引入进一步拓展了其在神经功能评估中的应用范围。然而，MRI也存在扫描时间较长、对钙化灶敏感度较低以及对某些金属植入物患者不适用等局限性。本研究创新性地提出了基于多模态MRI融合技术的优化方案，显著提高了复杂病例的诊断准确性，为临床决策提供了重要参考依据，同时为未来技术改进指明了方向。关键词：磁共振成像; 神经系统疾病; 多模态融合; 功能性磁共振成像; 诊断价值
Abstract
Magnetic resonance imaging (MRI) plays an indispensable role in modern medical imaging technology, particularly in the diagnosis of neurological disorders. This study aims to systematically evaluate the application value and limitations of MRI in diagnosing neurological diseases by retrospectively analyzing MRI data from 120 patients with neurological conditions and integrating clinical manifestations with pathological results for comprehensive assessment. The findings indicate that MRI, leveraging its high resolution and multiparametric imaging capabilities, can clearly delineate brain tissue structures and lesion characteristics, demonstrating significant advantages in the early diagnosis and precise localization of various diseases, including brain tumors, strokes, and demyelinating diseases. Furthermore, the introduction of advanced techniques such as functional MRI (fMRI) and diffusion tensor imaging (DTI) has expanded the scope of MRI applications in neurological function evaluation. However, MRI also exhibits certain limitations, such as longer scanning times, lower sensitivity to calcified lesions, and inapplicability to some patients with me tallic implants. Innovatively, this study proposes an optimized solution based on multimodal MRI fusion technology, which substantially enhances diagnostic accuracy in complex cases, providing critical reference for clinical decision-making and indicating potential directions for future technological improvements.
