What does normal signal in the diffusion-weighted images mean?

Would a large brain tumor show normal signal in diffusion-weighted images?

Thanks

visualizing corticospinal tracts
I' m a student master of medical imaging, and I was wondering which MRI technics are used to visualise the corticospinal tracts? Diffusion tensor imaging is one of them, I think...
kind regards
marleen michels, kuleuven.

LUNGS MRI
You are right! It is called the hyperpolarized nobel gases, mostly Helium-3 and Xenon-129. They are many centers around the world are conducting such experiments. Many techniques using the gas have been developed to investigate pulmonary pathphysiological changes such as ventilation, diffusion, elastis, etc. As an example, you can go the below link for detailed information:

Hi Tina,
i am not sure whether it will answer your question, but I found this diffusion tutorial helpful: http://ej.rsna.org/ej3/0095-98.fin/index.htm
