摘要
放射性粒子链是将125I粒子按照线性排列并置于管状导管中,使其剂量分布接近于圆柱形,进而适应腔道内的肿瘤放疗,发挥出单粒子所达不到的治疗效果。本文旨在综述125I放射性粒子链的发展历史、剂量分布、置入方法以及临床应用。
The radioactive particle chain is a linear array of 125I particles and placed in a tubular conduit.The dose distribution of the particle chain is similar to the shape of a cylinder.It may be adapted to the tumors in the lumen and exerts the radiotherapy effect that may not be achieved by single particles.This article aims to review the history of 125I radioactive particle chains,dose distribution,placement methods and clinical application.
