Magnetic resonance imaging (MRI) is conventionally used for the detection and diagnosis of multiple sclerosis (MS), often complemented by lumbar puncture-a highly invasive method-to validate the diagnosis. Additionally, MRI is periodically repeated to monitor disease progression and treatment efficacy. Recent research has focused on the application of artificial intelligence (AI) and radiomics in medical image processing, diagnosis, and treatment planning.
A review of the current literature was conducted, analyzing the use of AI models and texture analysis for MS lesion segmentation and classification. The study emphasizes common models, including U-Net, Support Vector Machine, Random Forest, and -Nearest Neighbors, alongside their evaluation metrics.
The analysis revealed a fragmented research landscape, with significant variation in model architectures and performance. Evaluation metrics such as Accuracy, Dice score, and Sensitivity are commonly employed, with some models demonstrating robustness across multi-center datasets. However, most studies lack validation in clinical scenarios.
The absence of consensus on the optimal model for MS lesion segmentation highlights the need for standardized methodologies and clinical validation. Future research should prioritize clinical trials to establish the real-world applicability of AI-driven decision support tools. This review provides a comprehensive overview of contemporary advancements in AI and radiomics for analyzing and monitoring emerging MS lesions in MRI.
传统上,磁共振成像(MRI)用于多发性硬化症(MS)的检测和诊断,通常辅以腰椎穿刺(一种侵入性很强的方法)来验证诊断。此外,还会定期重复进行MRI检查以监测疾病进展和治疗效果。最近的研究集中在人工智能(AI)和放射组学在医学图像处理、诊断和治疗规划中的应用。
对当前文献进行综述,分析AI模型和纹理分析在MS病变分割和分类中的应用。该研究重点介绍了常见模型,包括U-Net、支持向量机、随机森林和K近邻,以及它们的评估指标。
分析发现研究领域较为分散,模型架构和性能差异很大。常用的评估指标如准确率、骰子系数和灵敏度,一些模型在多中心数据集中表现出稳健性。然而,大多数研究缺乏临床场景下的验证。
在MS病变分割的最佳模型上缺乏共识,这凸显了标准化方法和临床验证的必要性。未来的研究应优先进行临床试验,以确定AI驱动的决策支持工具在现实世界中的适用性。本综述全面概述了AI和放射组学在分析和监测MRI中新出现的MS病变方面的当代进展。
