T1 and T2 weighted magnetic resonance imaging and DWI of the nasopharynx and neck were performed 1 week before radiotherapy, during radiotherapy at a dose of 60\u200aGy, and 1 month after radiotherapy. Pertinent measurements and related data were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>In comparison with that before radiotherapy, the ADC value of the nasopharyngeal primary lesion increased significantly during radiotherapy at a dose of 60\u200aGy and at 1 month after radiotherapy (F\u200a=\u200a187.160, P\u200a=\u200a0.000). When the dose of radiotherapy reached 60\u200aGy, the DWI signals from both the neck and the retropharyngeal lymph nodes were significantly lower than those before radiotherapy.<\/jats:p>\n
