探讨PET/CT对恶性肿瘤立体适形放射治疗的应用价值。利用肿瘤组织对~(18)F-FDG的特异性摄取可以精确诊断和确定肿瘤的范围及全身转移的情况和多层CT精确解剖定位、同机融合图像对放射治疗前的诊断、放疗中的定位和指导靶区勾画、制定放疗计划、放疗后的复查都有很大的帮助。
To investigate the value of PET / CT in the treatment of malignant tumors by stereotactic radiotherapy. The specific uptake of ~ (18) F-FDG by tumor tissue can accurately diagnose and determine the extent of the tumor and systemic metastases and the accurate anatomical location of multi-slice CT. The fusion images of the same organism can be used to diagnose and treat radiotherapy before radiotherapy Targeting and targeting the area outlined, the development of radiotherapy plans, review after radiotherapy have a great help.
