Despite advances in oncology, the local control of malignancies remains a formidable challenge. For the radiation oncologist, this challenge is approached by greater precision in the definition of the tumor and normal tissue with the intent of encompassing the former and excluding the latter from the high dose volume of treatment. Advances in diagnostic imaging have been incorporated into radiation therapy planning to achieve this goal. Recent developments in three dimensional treatment planning of CNS and pelvic malignancies illustrate the extent to which radiation oncology has come to rely on diagnostic imaging and the promise it offers for improvement in clinical care.
尽管肿瘤学取得了进展，但恶性肿瘤的局部控制仍然是一项艰巨的挑战。对于放射肿瘤学家来说，应对这一挑战的方法是更精确地界定肿瘤和正常组织，目的是涵盖前者并将后者排除在高剂量治疗体积之外。诊断成像的进展已被纳入放射治疗计划以实现这一目标。中枢神经系统和盆腔恶性肿瘤三维治疗计划的最新进展说明了放射肿瘤学在多大程度上依赖于诊断成像及其为改善临床护理带来的前景。
