概括

大脑MRI (磁共振成像) 的强度缩放使图像数据协调一致,而不依赖内部参考区域. T1w/T2w比率的计算显示出神经成像研究中一致量化的前景.

科学领域:

神经成像是一种神经成像.
量化MRI是指数量化的MRI.
生物医学工程生物医学工程

背景情况:

传统的大脑MRI强度缺乏标准化的尺度,阻碍了准确的量化.
由于广泛的疾病影响,大脑内的参考区域可能无法可靠地进行缩放.
本综述侧重于强度缩放方法,这些方法避免了大脑内部参考区域.

结论:

强度缩放,特别是T1w/T2w比率,为大脑MRI数据提供了生物学上有意义的协调.
虽然有希望,但关于生物基础的方法问题和不确定性仍然存在.
需要进一步验证,特别是对于超出T1w/T2w比率计算的缩放方法.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
