Magnetic resonance imaging (MRI) provides varying tissue contrast images of internal organs based on a strong magnetic field. Despite the non-invasive advantage of MRI in frequent imaging, the low contrast MR images in the target area make tissue segmentation a challenging problem. This paper demonstrates the potential benefits of image-to-image translation techniques to generate synthetic high tissue contrast (HTC) images. Notably, we adopt a new cycle generative adversarial network (CycleGAN) with an attention mechanism to increase the contrast within underlying tissues. The attention block, as well as training on HTC images, guides our model to converge on certain tissues. To increase the resolution of HTC images, we employ multi-stage architecture to focus on one particular tissue as a foreground and filter out the irrelevant background in each stage. This multi-stage structure also alleviates the common artifacts of the synthetic images by decreasing the gap between source and target domains. We show the application of our method for synthesizing HTC images on brain MR scans, including glioma tumor. We also employ HTC MR images in both the end-to-end and two-stage segmentation structure to confirm the effectiveness of these images. The experiments over three competitive segmentation baselines on BraTS 2018 dataset indicate that incorporating the synthetic HTC images in the multi-modal segmentation framework improves the average Dice scores 0.8%, 0.6%, and 0.5% on the whole tumor, tumor core, and enhancing tumor, respectively, while eliminating one real MRI sequence from the segmentation procedure.

异柠檬酸脱氢酶(IDH)突变和1 p/19 q共缺失状态是胶质瘤的重要预后标志。目前,它们是使用侵入性程序确定的。我们的目标是开发基于人工智能的方法来非侵入性地确定MRI中的这些分子改变。为此,2648例胶质瘤患者的术前MRI扫描(II-IV级)从华盛顿大学医学院收集(WUSM; n = 835)和公开可用的数据集,即脑肿瘤分割(BraTS; n = 378),LGG 1 p/19 q(n = 159),Ivy胶质母细胞瘤Atlas项目(Ivy GAP; n = 41)、癌症基因组图谱(TCGA; n = 461)和伊拉斯谟神经胶质瘤数据库(EGD; n = 774)。提出了一种2.5D混合卷积神经网络,通过利用来自MR扫描的成像特征和来自临床记录和肿瘤位置的先验知识特征,同时定位肿瘤并对其分子状态进行分类。模型在一个内部(TCGA)和两个外部(WUSM和EGD)测试集上进行了测试。对于IDH,表现最好的模型在内部、WUSM和EGD测试集上分别实现了0.925、0.874、0.933的受试者操作特征下的面积(AUROC)和0.899、0.702、0.853的精确-召回曲线下的面积(AUPRC)。对于1 p/19 q,最佳模型在这三个数据分割上分别实现了0.782,0.754,0.842的AUROC和0.588,0.713,0.782的AUPRC。该模型对未知数据的高准确性展示了其泛…

脑肿瘤分割是肿瘤体积分析和人工智能算法的关键任务。然而,这是一个耗时的过程,需要神经放射学专业知识。虽然已经有广泛的研究集中在优化成人人群中的脑肿瘤分割,但关于AI引导的儿科肿瘤分割的研究很少。此外,儿童和成人脑肿瘤的MRI信号特征不同,需要开发专门为儿童脑肿瘤设计的分割算法。我们开发了一个分割模型,该模型在来自The Hospital for Sick Children(加拿大安大略省多伦多市)的患有低级胶质瘤(pLGG)的儿科患者的磁共振成像(MRI)上进行训练。该模型利用深度多任务学习(dMTL),将肿瘤的遗传变异分类器作为辅助任务添加到主网络中,最终提高分割结果的准确性。
