Abstract

This work aimed to explore the application value of deep learning-based magnetic resonance imaging (MRI) images in the identification of tuberculosis and pneumonia, in order to provide a certain reference basis for clinical identification. In this study, 30 pulmonary tuberculosis patients and 27 pneumonia patients who were hospitalized were selected as the research objects, and they were divided into a pulmonary tuberculosis group and a pneumonia group. MRI examination based on noise reduction algorithms was used to observe and compare the signal-to-noise ratio (SNR) and carrier-to-noise ratio (CNR) of the images. In addition, the apparent diffusion coefficient (ADC) value for the diagnosis efficiency of lung parenchymal lesions was analyzed, and the best value was selected. The results showed that the MRI image after denoising by the deep convolutional neural network (DCNN) algorithm was clearer, the edges of the lung tissue were regular, the inflammation signal was higher, and the SNR and CNR were better than before, which were 119.79 versus 83.43 and 12.59 versus 7.21, respectively. The accuracy of MRI based on a deep learning algorithm in the diagnosis of pulmonary tuberculosis and pneumonia was significantly improved (96.67% vs. 70%, 100% vs. 62.96%) ( < 0.05). With the increase in value, the CNR and SNR of MRI images all showed a downward trend ( < 0.05). Therefore, it was found that the shadow of tuberculosis lesions under a specific sequence was higher than that of pneumonia in the process of identifying tuberculosis and pneumonia, which reflected the importance of deep learning MRI images in the differential diagnosis of tuberculosis and pneumonia, thereby providing reference basis for clinical follow-up diagnosis and treatment.

摘要

本研究旨在探讨基于深度学习的磁共振成像(MRI)图像在肺结核和肺炎识别中的应用价值,为临床鉴别提供一定的参考依据。本研究选取 30 例住院肺结核患者和 27 例肺炎患者作为研究对象,分为肺结核组和肺炎组。采用基于降噪算法的 MRI 检查,观察并比较图像的信噪比(SNR)和载噪比(CNR)。此外,还分析了表观扩散系数(ADC)值对肺实质病变诊断效率的影响,并选择最佳值。结果显示,深度卷积神经网络(DCNN)算法降噪后的 MRI 图像更清晰,肺组织边缘规则,炎症信号更高,SNR 和 CNR 均优于未降噪前,分别为 119.79 比 83.43 和 12.59 比 7.21。基于深度学习算法的 MRI 对肺结核和肺炎的诊断准确率明显提高(96.67%比 70%,100%比 62.96%)( < 0.05)。随着 值的增加,MRI 图像的 CNR 和 SNR 均呈下降趋势( < 0.05)。因此,在鉴别肺结核和肺炎的过程中,发现特定序列下肺结核病变的阴影高于肺炎,这反映了深度学习 MRI 图像在肺结核和肺炎鉴别诊断中的重要性,为临床随访诊断和治疗提供了参考依据。
