Brain Diffusion MRI Series — Part 2: DWI brightness and true diffusion restriction
In Part 1, we learned the basic pairing: when we see a bright area on DWI, we also look at its appearance on the ADC map. Now let us explore, step by step, why this is necessary. Our aim is to understand whether the brightness we see really indicates reduced water movement. We have found a bright area on DWI what do we do next Let us start with this question: is water movement actually reduced in this region? Brightness on DWI may suggest this, but it does not provide the ans

Brain Diffusion MRI Series — Part 1: Understanding DWI and ADC
RCD | Brain MRI Diffusion Series | Part 01 / 12 When water movement decreases, that area generally remains brighter on high-b-value DWI. However, to determine whether this brightness truly results from restriction, we look at ADC. What are we looking at with diffusion MRI Water molecules within tissues constantly make small, random movements. Diffusion MRI allows us to assess how freely water can move within its surroundings. To understand this, imagine two environments:
