Objective To investigate the differential diagnosis value of 1H magnetic resonance spectroscopy (1H-MRS) and (superscript 99m)Tc-methoxy isobutyl isonitrile single photon emission computed tomography on postradiotherapy relapse and radionecrosis. Methods 1H-MRS and SPECT were performed in all 35 cases.

Two patients had radionecrosis (1 soft tissue and 1 bone) requiring hyperbaric oxygen. Eighteen patients (37%) had prolonged tube feedings (N3 months) after treatments because of seere dysphagia or aspiration.
