Imaging the spinal cord is normally performed at lower magnetic field with limited resolution. In this study, 13 ex-vivo cervical spinal cords have been scanned at 9.4T to provide high-resolution images. A variation of the position of the rostral brachial motorneurons among the cords was used to classify the samples into normal and pre-fixed types. For each segment, the length and GM/WM total areas were measured. A high resolution MRI template of the normal type samples was created to assist registration and delineation of spinal cord structures and improve the accuracy of diagnostic radiology.
