碘-125体内照射治疗脑胶质瘤的方法被国内外学者越来越多的应用,脑胶质瘤复发时间及生存时间明显延长,目前大多应用微创的手术方法,精度进一步提高。体内照射法即将放射性同位素植入肿瘤组织内进行照射,又称间质内放疗。是按“放射量和距离的平方成反比”的规率,可以使靶区达到较高的放射剂量,而周围正常组织受量很低。Kleihues和Cavenee于2000年发表的WHO神经系统
Iodine-125 in vivo irradiation treatment of glioma method is more and more applications by scholars at home and abroad, glioma recurrence time and survival time was significantly longer, most of the current minimally invasive surgical methods, the accuracy is further improved. In vivo irradiation is about radioisotope implantation in tumor tissue irradiation, also known as interstitial radiotherapy. Is based on the “inversely proportional to the square of the amount of radiation and distance” of the rate, you can make the target area to achieve a higher dose of radiation, while the surrounding normal tissue volume is very low.
