Parotid
glands are highly radiosensitive, while the utilization of parotid sparing
technique decreases the irradiation, and thus may reduce radiation therapy
damage. In this study, we demonstrate a graded alteration in the perfusion
characteristics of parotid glands, with the respect of parotid-sparing volume
provided by the intensity modulated radiotherapy (IMRT) technique.
