摘要:

提出多尺度残差神经网络(multi-scale resnet, MSResnet)。采用不同大小的卷积核对图像进行多尺度信息采集,并对神经网络进行残差学习,避免网络退化。对核磁共振图像(magnetic resonance imaging, MRI)进行标准化处理,利用MSResnet模型在阿尔茨海默症(Alzheimer's disease, AD)和正常受试者(normal control, NC)获得的分类准确率为99.41%,在AD和轻度认知障碍(mild cognitive impairment, MCI)获得分类准确率为97.35%。与已有的算法相比,本研究提出的算法的分类准确率得到了明显的提高。

Abstract:

A multi-scale resnet (MSResnet) method was proposed in this paper, which employed multi-scale convolution kernel to extract multi-scale information of structural magnetic resonance imaging MRI, and carried out residual learning for neural network, so as to avoid network degradation. After the gray scale standardization of MRI, the 99.41% classification precision was obtained by using the MSResnet model between Alzheimer's disease (AD) and normal control (NC), and the classification accuracy between AD and mild cognitive impairment (MCI) was 97.35%. Compared with the existing approaches, the algorithm proposed in this paper improved the classification accuracy significantly.

Key words: MSResnet, magnetic resonance imaging, Alzheimer's disease, gray scale standardization
