There are two major issues in the MRI image diagnosis task for Parkinson's disease. Firstly, there are slight differences in MRI images between healthy individuals and Parkinson's patients, and the medical field has not yet established precise lesion localization standards, which poses a huge challenge for the effective prediction of Parkinson's disease through MRI images. Secondly, the early diagnosis of Parkinson's disease traditionally relies on the subjective judgment of doctors, which leads to insufficient accuracy and consistency. This article proposes an improved YOLOv5 detection algorithm based on deep learning for predicting and classifying Parkinson's images.
This article improves the YOLOv5s network as the basic framework. Firstly, the CA attention mechanism was introduced to enable the model to dynamically adjust attention based on local features of the image, significantly enhancing the sensitivity of the model to PD related small pathological features; Secondly, replace the dynamic full dimensional convolution module to optimize the multi-level extraction of image features; Finally, the coupling head strategy is adopted to improve the execution efficiency of classification and localization tasks separately.
We validated the effectiveness of the proposed method using a dataset of 582 MRI images from 108 patients. The results show that the proposed method achieves 0.961, 0.974, and 0.986 in Precision, Recall, and mAP, respectively, and the experimental results are superior to other algorithms.
The improved model has achieved high accuracy and detection accuracy, and can accurately detect and recognize complex Parkinson's MRI images.
This algorithm has shown good performance in the early diagnosis of Parkinson's disease and can provide clinical assistance for doctors in early diagnosis. It compensates for the limitations of traditional methods.
在帕金森病的 MRI 图像诊断任务中存在两个主要问题。首先,健康个体和帕金森病患者的 MRI 图像之间存在细微差异,并且医学领域尚未建立精确的病变定位标准,这对通过 MRI 图像有效预测帕金森病构成了巨大挑战。其次,帕金森病的传统早期诊断依赖于医生的主观判断,这导致准确性和一致性不足。本文提出了一种基于深度学习的改进 YOLOv5 检测算法,用于预测和分类帕金森图像。
本文改进了 YOLOv5s 网络作为基本框架。首先,引入 CA 注意力机制,使模型能够根据图像的局部特征动态调整注意力,显著增强模型对 PD 相关小病理特征的敏感性;其次,替换动态全维卷积模块,优化图像特征的多级提取;最后,采用耦合头策略分别提高分类和定位任务的执行效率。
我们使用来自 108 名患者的 582 张 MRI 图像数据集验证了该方法的有效性。结果表明,所提出的方法在精度、召回率和 mAP 方面分别达到了 0.961、0.974 和 0.986,实验结果优于其他算法。
改进后的模型在帕金森病的早期诊断中取得了较高的准确率和检测准确率,能够准确地检测和识别复杂的帕金森 MRI 图像。
该算法在帕金森病的早期诊断中表现出良好的性能,可以为医生的早期诊断提供临床辅助,弥补了传统方法的局限性。
