U-Net, an essential model within CNNs, has gradually become a research focus in the field of medical image segmentation due to its remarkable segmentation performance. This paper presents a comprehensive overview of brain tumor segmentation methods based on CNNs. Firstly, it introduces common medical image datasets in the field of brain tumor segmentation. Secondly, it offers detailed reviews on the common improvements to 2D U-Net, 3D U-Net, and improvements based on other CNNs for brain tumor segmentation. Finally, it discusses the future development directions of CNNs for brain tumor segmentation.</p> Yuzhuo Li Lihong Zhang Yingbo Liang Chongxin Xu Tong Liu Copyright (c) 2024 Yuzhuo Li, Lihong Zhang, Yingbo Liang, Chongxin Xu, Tong Liu https://creativecommons.org/licenses/by-nc-sa/4.0 2024-12-13 2024-12-13 11 10.4108/eetel.6080 A Review of Deep Learning Methods for Brain Tumor Detection https://publications.eai.eu/index.php/el/article/view/8441 <p>A brain tumor is a serious neurological condition caused by the growth of abnormal cells in various regions of the brain, leading to a variety of health issues. Although the specific causes of brain tumors are not yet fully understood, known risk factors include genetic predisposition, ionizing radiation, viral infections, and exposure to certain chemicals. With the advancement of deep learning technology, computer-aided diagnosis systems can offer crucial support for the early diagnosis of brain tumors. Brain tumor image classification using deep learning has emerged as a prominent area of research. This article begins by summarizing the publicly available datasets frequently utilized in brain tumor classification tasks. It then provides an overview of the models commonly applied for diagnosing brain tumors. Following this, the paper reviews the advancements made in the field of brain tumor classification research to date. Finally, it highlights the future trends and challenges in brain tumor classification.</p> Shuaichao Wen Copyright (c) 2024 Shuaichao Wen https://creativecommons.org/licenses/by-nc-sa/4.0 2025-02-07 2025-02-07 11 10.4108/eetel.8441
