Havaei等人[13]构建了一个双路径的2D CNN脑肿瘤分割网络,通过采用不同大小的卷积核来提取不同的背景特征信息,该网络包含局部和全局路径。然而,补丁研究架构缺乏空间连续性,需要大量的存储空间,导致效率低下。基于编码和解码的概念,基于FCN的脑肿瘤分割网络对整个脑图像中的每个像素进行分类和预测,从而完成分割,这显然...

1. Introduction 脑瘤是生长在人脑中的异常细胞,被认为是一种常见的神经系统疾病,对人体健康危害极大[1]。作为辅助诊断和治疗脑瘤的重要方法,在脑磁共振图像上进行脑瘤自动分割在临床医学上具有重要意义[2]。最常见的恶性脑肿瘤是胶质瘤,可进一步分为高等级胶质瘤(HGG)和低等级胶质瘤(LGG)[3]。磁共振成像(MRI)...
MRI and MRS(Luncheon Educational Seminar 2 Progress in diagnostic techniques for brain tumors) The role of any imaging modality in the evaluation of brain tumors is first and foremost the detection of such a tumor when clinical suspicion exists. In addition, characterization of the tumor with r ...
One of the most important advantages of MRI is influence of multiple tissue and machine parameters on the signal intensities. In addition, capability of imaging in various planes and multislices is another advantage for the brain tumor diagnosis. The coronal image is important when the abnormal ...
tumor’s location, size, and potential impact on adjacent brain structures, critical for treatment planning. However, the interpretation of MRI scans is highly reliant on the expertise of radiologists and can be time-consuming, highlighting the need for assistive technologies to improve diagnostic ...
