WebThe term MRI hyperintensity defines how components of the scan look. Most MRI reports are black and white with shades of gray. However, the hyperintensity area appears a little lighter comparatively. On the contrary, hypointensity would be blacker in color. The MRI hyperintensity reflects the existence of lesions in the brain. The simplest way to think about the multitude of sequences available on modern scanners is to divide them according to the dominant influence on the appearance of tissues. This leads to a division of all sequences into proton density (PD) weighted, T1 weighted, T2 weighted, diffusion weighted, flow … See more When describing most MRI sequences we refer to the shade of grey of tissues or fluid with the word intensity, leading to the following absolute terms: 1. high signal intensity = white 2. … See more T1 weighted (T1W) sequences are part of almost all MRI protocols and are best thought of as the most 'anatomical' of images (historically … See more Given that nuclear magnetic resonance of protons (hydrogen ions) forms the major basis of MRI, it is not surprising that signal can be weighted to … See more T2 weighted (T2W) sequences are part of almost all MRI protocols.
