The table shows the findings of intraoperative magnetic resonance imaging (ioMRI) and postoperative (PostOP) MRI sequences as well as the long-term outcome of patients as rated by British Medical Research Council scale (0 = no contraction, 1 = flicker or trace of contraction, 2 = active movement with gravity eliminated, 3 = active movement against gravity, 4 = active movement against gravity and resistance, 5 = normal power); N/A = not available, PreOP = preoperatively, + = positive MRI signal, - = negative MRI signal, NND = no new surgery-related deficit).
