This is not a partisan issue—it is a human one. It is about dignity, respect, and the recognition that every individual should have the right to determine how they meet life’s final chapter. The evidence is clear, the safeguards are strong, and the need is undeniable. The Delaware legi...
CNR是指两种组织信号强度差值与背景噪声的标准差之比(上图)。具有足够信噪比的MR图像,其CNR受三个方面的影响:(1)组织间的固有差别,即两种组织的T1值、T2值、质子密度、运动等的差别,差别大者则CNR较大,对比越好。如果组织间的固有差别很小,即便检查技术用得最好,CNR也很小。(2)成像技术,包括场强、所用序列、...

零回波时间(ZTE)成像是一种MRI技术,产生的图像类似于X线摄影或CT获得的图像。在ZTE MRI中,矿化的小梁骨基质,特别是皮质骨(两者都具有低质子密度(PD))的极短T2信号以独特的序列设置进行采样。此外,ZTE序列的PD加权导致软组织之间的对比度降低。因此,随着灰度从黑到白,反之亦然,ZTE成像提供了类似于X线摄影和CT的...
3.如需观察垂体微腺瘤需采用半剂量造影剂行多期动态增强扫描,为了保证时间分辨率,扫描层数不宜过多(4-5层)。在多期动态增强扫描完成后可加扫SAGFS T1+C及COR FS T1+C序列。 更多磁共振知识,请登录www.mrihome.com/www.mrihome.cn
CHICAGO, Dec. 1 (Xinhua) -- An MRI system called uMR Omega with a ultra-wide bore of 75 cm was unveiled Sunday at the ongoing 105th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA), which began Sunday and runs till Friday. ...
A wide range of molecules and nanoparticles have been investigated as agents for contrast enhanced MRI and fluorescence imaging in cancer diagnosis. However, a single material with dual modal imaging of MRI and TPF is rarely reported. We found that Mn₃[Co(CN)₆]₂@SiO₂ nanocubes can ...
