Hello!
I've read article "High Resolution Diffusion Tensor Imaging of Human Nerves in Forearm"
I am interesting for DTI on dorsal penile nerves.
What do you think about it? Is it possible or not?
I don't think so... In that article talked about forearm nerves. Cutaneus braches of n. radialis have same thickness as n. dorsalis penis.
We've made MRI image (attached picture), but we can't make DTI visualisation.
If you acquire very high resolution data, and at the correct b-value, then this should be possible. I would suggest using a technique for selective k-space - GE calls this FOCUS, Siemens call it ZoomIt - to acquire a limited FOV in k-space and therefore very high resolution. I would suggest using this technique to acquire something around 0.5mm (500 micron) resolution with at least 2 averages. Your radiographer will suggest the best b-value, but I would try somewhere between 300 and 500. You shouldn't need to acquire many diffusion directions (I think 25 would be sufficient).
