Bland-Altman分析显示,Dark-Blood血LGE与常规浅色血LGE的梗死面积相关性良好(r = 0.950, P < 0.001),两种方法之间无显著偏差(- 1.2%,P = 0.15)。 总共24张匹配的(第7周)LGE MRI和组织病理学层面可用,并用于Dark-Blood LGE的组织病理学验证...

肥厚型心肌病心肌纤维化氨基末端B型脑钠肽前体高敏肌钙蛋白T目的:探讨钆延迟增强磁共振(LGE-MRI)检测的肥厚型心肌病(HCM)心肌纤维化与血浆氨基末端B型脑钠肽前体(NT-proBNP),高敏肌钙蛋白T(hs-cTnT)水平的相关性.方法:选取28例经完整临床资料诊断为HCM的患者行心脏磁共振成像(CMR)检查[包括心脏电影,延迟钆增强...
MRI(LGE-MRI)是既往心肌梗死后局限性MF检测的临床应用标准,而当今T1 mapping技术在对心肌弥漫性MF的检测和定量评价中更具优势,心脏功能MRI技术如扩散张量成像(DTI)和扩散加权成像(DWI)无需对比剂即可定量评估心肌微细结构,在MF检测方面亦表现出较大的应用潜能.综述T1 mapping、DTI、DWI等技术进展并与LGE-MRI进行...
We propose a deep learning-based method to segment the left ventricle's endocardium and epicardium in LGE-MRI. To this end, a multi-scale fully convolutional neural network with skip-connections (U-Net) and residual units is applied to solve the multiclass segmentation problem. As a loss ...
LGE-MRI from 60 AF patients were analyzed applying five different approaches for fibrosis segmentation: an histogram-based (H-6SD), the image intensity ratio (IIR), the blood pool normalization (BP), the Chan-Vese (CV) and the graph-cut (GC) method. For each method we quantified the ...
A second set of manual labels exists for 30 patients of the target LGE CMR images, but are annotated on different MRI sequences (bSSFP and T2-weighted). Again, we use multi-atlas label fusion with a consistency constraint to further refine our noisy labels if additional annotations in other...
At baseline, LGE-CMR and elevated procollagen III N-terminal propeptide, sphingosine-1-phosphate, and globotriaosylsphingosine were the most prevalent indicators of early Fabry-related pathology. LGE was already present in 58.8% of patients with normal left ventricular mass index. 15.2% of patients...
