语义模块采用改进的Swin Transformer模块从包括FLAIR、T1、T1ce和T2在内的多模态MRI扫描中提取深层语义特征。边缘检测模块旨在通过使用卷积网络作为骨干,并设计边缘空间注意力块(ESABs)来增强特征,从而提取边缘特征。考虑到MRI模态的特征,仅选择FLAIR和T1ce作为边缘检测模块的输入。特征融合模块由多个多特征推理块(MFIBs)...

Wernicke’s encephalopathyAlthough a perturbed cerebral blood flow (CBF) has been reported in patients with Wernicke's encephalopathy (WE), its clinical meaning is still elusive. A retrospective analysis of 10 patients (male, 6; mean age, 57.7 years) with WE between October 2012 and May 2018 ...
of theinner body structuresbouncing back to the transducer, which then translates them into a pixelated image displayed on the connected monitor. The density of the tissues here defines how echogenic they are, meaning what amount of sound will they resonate back (echo) or pass through themselves...
T2-FLAIR image Medical students and non-radiologists are often taught to look at the the "color" of CSF or other fluids to determine the type of "weighting" — dark CSF means "T1-weighting" and bright CSF means "T2-weighting". Although this simple scheme may have worked 20 years ago, ...
Our proposed framework was trained and validated using multi-coil FLAIR brain MRI data from the fastMRI brain dataset[47]. This dataset comprises complex-valued k-space data captured using both 3 T and 1.5 T scanners using 16 receiver coils and features axial slices. For the out-of-distributi...
wI为低信号,T:wI为高信号,周围有黑环,T:Flair为低信号,DwI为低信号,病变周围无水肿。结论不同期别脑出血的MRI表现具有特征性,超急性期、急性期出血在T,Flair、DwI均表现为低信号,而亚急性期出血在T.wI表现为高信号,慢性期、残腔期T:wI病变周围有低信号环为特点。【关键词】脑出血;扩散加权成像;磁共振成像...

bipolar disorder16, and major depressive disorder17,18. In these applications, various magnetic resonance imaging (MRI) modalities have been employed such as structural T1-weighted imaging, T2-FLAIR-weighted imaging, diffusion tensor imaging (DTI), functional MRI (fMRI), and arterial spin labeling ...
