摘要:

帕金森病(Parkinson's Disease,PD)是由脑中多巴胺能神经元的进行性变性引起的最常见类型的神经系统疾病之一。尽管这种神经退行性疾病没有固定的治疗方法,但早期诊断和早期治疗可以帮助患者获得更好的生活质量。磁共振成像(MRI)是近年来最流行的诊断工具之一,因为它避免了有害的辐射。在本文中,我们调查的可行性,门使用MRI自动诊断PD。我们提出的方法有三个主要步骤:1)预处理,2)特征提取,3)分类。FreeSurfer库用于第一步和第二步。在分类方面,采用了逻辑回归(LR)、随机森林(RF)和支持向量机(SVM)三种主要的分类器,并比较了它们的分类能力。帕金森病进展标志物倡议(PPMI)的数据集被用来评估所提出的方法。该系统被证明是有前途的辅助诊断PD。

英文摘要:

Parkinson's Disease (PD) is one of the most common types of neurological diseases caused by progressive degeneration of dopamin- ergic neurons in the brain. Even though there is no fixed cure for this neurodegenerative disease, earlier diagnosis followed by earlier treatment can help patients have a better quality of life. Magnetic Resonance Imag- ing (MRI) has been one of the most popular diagnostic tool in recent years because it avoids harmful radiations. In this paper, we investi- gate the plausibility of using MRIs for automatically diagnosing PD. Our proposed method has three main steps : 1) Preprocessing, 2) Fea- ture Extraction, and 3) Classification. The FreeSurfer library is used for the first and the second steps. For classification, three main types of classifiers, including Logistic Regression (LR), Random Forest (RF) and Support Vector Machine (SVM), are applied and their classification abil- ity is compared. The Parkinsons Progression Markers Initiative (PPMI) data set is used to evaluate the proposed method. The proposed system prove to be promising in assisting the diagnosis of PD.
