PET/CT在体部γ刀定位中应用体会

Application of PET/CT Orientation Gamma Knife in the Body Position

目的:阐述PCT/CT在体部γ刀定位中的应用。方法:2007-05—2008-05,利用PET/CT设备对120例患者进行体部γ刀定位及图像融合。结果:用PET/CT扫描可在不用碘造影剂增强情况下进行肿瘤有效显像,较单纯CT定位获得更丰富和准确的图像信息,有助于指导靶区(GTV)的勾画。结论:PET/CT在γ刀治疗定位中明显提高了GTV的定位精度,增加了碘过敏患者的治疗机会。

Objective To elaborate the application of PCT/CT orientation Gamma Knife in the body. Methods From May, 2007 to May, 2008, PET/CT equipment was used on 120 cases with gamma knife body positioning and image fusion. Results The PET/CT scan may not have iodine in the contrast agent to enhance the effective conduct of tumor imaging and CT position provides more simple and more accurate image information to guide target（GTV） of the outline. Conclusion The PET/CT in the gamma knife treatment can improve in the positioning accuracy of GTV, and improve treatment opportunity for iodine allergy patients.
