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.
