Abstract

Lung nodule detection is clinically crucial but challenging and time-consuming. The development of automated segmentation approaches could be helpful. To assess the capability of deep learning methods for lung diagnosis, this paper compares recent deep learning models and evaluates their performance. We implemented several preprocessing steps, including windowing, thresholding, and resizing, to improve the image quality, adjust the image dimension suitable for the network, and focus on specific areas of interest within an image. The evaluation was conducted on the Lung Image Database Consortium (LIDC) dataset using Dice similarity coefficient (DSC) and Hausdorff distance (HD) metrics with model complexity parameters for a multifaceted comparison of the models. The experiments showed that the highest accuracy among the five chosen models (97.80% DSC and 1.29 HD) was reached by the Connected-UNets model, which also has the highest computational complexity. In this paper, we quantitatively evaluated and compared 5 deep learning models namely Salient Attention UNet, Connected-UNets, DDANet, UTNet, and EdgeNeXt. The evidence-based overview of current deep learning achievements for the clinical community investigated in this study can be useful to the research community in developing a new model and, thus, designing computer-aided detection and diagnosis (CAD) systems.

用于肺结节分割的深度学习模型:比较研究
肺结节检测对临床至关重要,但具有挑战性且耗时。开发自动分割方法可能会有所帮助。为了评估深度学习方法在肺部诊断方面的能力,本文比较了最近的深度学习模型并评估了它们的性能。我们实施了几个预处理步骤,包括开窗、阈值化和调整大小,以提高图像质量,调整适合网络的图像维度,并关注图像中特定的感兴趣区域。评估在肺部图像数据库联盟(LIDC)数据集上进行,使用骰子相似系数(DSC)和豪斯多夫距离(HD)指标,并结合模型复杂度参数,对模型进行了多方面的比较。实验结果表明,在所选的五个模型中,Connected-UNets 模型的准确率最高(DSC 为 97.80%,HD 为 1.29),同时该模型的计算复杂度也最高。本文对 Salient Attention UNet、Connected-UNets、DDANet、UTNet 和 EdgeNeXt 五种深度学习模型进行了定量评估和比较。本研究对目前临床界深度学习成果的循证概述,有助于研究界开发新模型,从而设计计算机辅助检测和诊断(CAD)系统。
