随着放射性125I粒子的问世、CT影像技术的进步以及计算机技术的广泛应用,放射性粒子组织间插植治疗得到了较快发展,目前已成为1种新的恶性肿瘤治疗方法[1,2]。我院自2005年9月～2007年5月采用CT影像引导下或直视下放射性125I粒子植入联合外放疗治疗66例恶性肿瘤患者,取得了满意 With the advent of 125I radioactive particles, the progress of CT imaging technology and the widespread use of computer technology, radioactive seed interstitial implantation therapy has developed rapidly, and now it has become a new treatment of malignant tumors [1,2]. Our hospital from September 2005 to May 2007 under the guidance of CT images or under direct vision of 125I radioactive seed implantation combined with external beam radiotherapy in 66 patients with malignant tumors and achieved satisfactory
