scan matrices and steps
Hello,
I've just joined this forum because I'm a Japanese-English translator and often translate MRI related material, but my knowledge is a bit patchy. I have a rather basic question. Part of a product specification goes (translated):
Scan Matrix: 64 – 1024 x 64 – 1024; 4 steps per

I assume this is 4 steps per scan, but wanted to check just in case. Also could anyone explain what is meant by steps in this context?

Thanks very much

SPIO in vivo tracing of stem cells in humans
I am planning clinical trial with autologous stem cell implantation by patients in end stage PAD (Rutherford category IV and V). I would like to label the bone marrow stem cells to be able to trace them with MRI. Anybody knows some reasonable solutions or helpful literature?
please email me: jedrzej.kosiuk@meduniwien.ac.at

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

T1 FAT SAT PRE AND POS GADO
The contrast agent causes this difference. Contrast agents reduce the T1 time in tissues where they have accumulated depending on blood flow and vascular permeability. Caused by this, tissues after an application of contrast agents will differ in shortening of the T1 time, and the same imaging parameters result in other image appearance.
Some helpful links for musculoskeletal imaging and Fat Sat:

Hope this helps
