Conformal radiation with intensity-modulated radiation therapy, IMRT, is a radiation technique that potentially can minimize the dose to salivary glands and thereby decrease the incidence of xerostomia. Precise target determination and delineation is most important when using salivary gland-sparing techniques of IMRT. The reduction of xerostomia may be achieved by sparing the salivary glands on the noninvolved oral cavity and keeping the mean parotid gland dose of < 26-30 Gy if the treatment of disease is not compromised and parotid function preservation is desired.
适形放疗联合调强放疗（IMRT）是一种放射技术，有可能将唾液腺的剂量降至最低，从而降低口干症的发生率。在使用IMRT的唾液腺保留技术时，精确的靶区确定和勾画最为重要。如果疾病治疗不受影响且希望保留腮腺功能，通过保留未受累口腔的唾液腺并使腮腺平均剂量<26 - 30 Gy，可能实现口干症的减轻。
