For the
past few decades, MRI has been increasingly used for identifying peripheral
nerve injury, causing chronic and neuropathic pain. Unfortunately, a
substantial number of MRI examinations fails to find the causative nerve
damage, possibly because it is too subtle or small. Recent developments of
PET-MRI demonstrated improved detection capability of the nerve damage, but the
precise anatomic characterization of the detected lesion still remains
challenging. We introduce high-resolution 3D steady-state imaging sequences at
7T that enable examination of microstructures of peripheral nerves in
extremities. We believe our methods have great potential for improving diagnosis
of various pain syndromes.
