摘要:

医学脑图像分析是计算机辅助诊断(CAD)系统中必不可少的步骤。在过去的几年里,硬件和软件的进步已经导致了各种疾病的分割和分类的改进。在目前的工作中,我们回顾了已发表的文献系统和算法,允许分类,识别和检测白质高信号(WMH)的脑MRI图像,特别是在缺血性中风和脱髓鞘疾病的情况下。对于选择标准,我们使用了文献计量网络。在总共140份文件中,我们选择了38篇涉及本研究主要目标的文章。基于对修订文件的分析和讨论,深度学习新模型的研究和建议不断增长,以实现缺血性和脱髓鞘病变分割的最高准确性和可靠性。发现了具有指标(Dice Score,DSC:0.99)的模型,但是由于使用小数据集和缺乏再现性,几乎没有实际应用。因此,主要结论是建立多学科研究小组,以克服CAD的发展和它们在临床环境中的完全利用之间的差距。

英文摘要:

Medical brain image analysis is a necessary step in Computer Assisted /Aided Diagnosis (CAD) systems. Advancements in both hardware and software in the past few years have led to improved segmentation and classification of various diseases. In the present work, we review the published literature on systems and algorithms that allow for classification, identification, and detection of White Matter Hyperintensities (WMHs) of brain MRI images specifically in cases of ischemic stroke and demyelinating diseases. For the selection criteria, we used the bibliometric networks. Out of a total of 140 documents we selected 38 articles that deal with the main objectives of this study. Based on the analysis and discussion of the revised documents, there is constant growth in the research and proposal of new models of deep learning to achieve the highest accuracy and reliability of the segmentation of ischemic and demyelinating lesions. Models with indicators (Dice Score, DSC: 0.99) were found, however with little practical application due to the uses of small datasets and lack of reproducibility. Therefore, the main conclusion is to establish multidisciplinary research groups to overcome the gap between CAD developments and their complete utilization in the clinical environment.
