深吸气屏气技术在放疗中的运用

Application of deep inspiration breath-hold technique in radiotherapy

在胸腹部肿瘤的放疗中,呼吸运动对放疗的负面影响贯穿放疗全流程。深吸气屏气(DIBH)是放疗中呼吸运动管理的一种方法,能够在放疗全流程中减少呼吸运动对放疗带来的负面影响。同时,DIBH技术与其他呼吸运动管理措施(四维CT、门控技术、追踪等)相比有其自身的特点和操作要求。本文的目的是对DIBH技术的优缺点及应用现状进行介绍。

In radiotherapy for thoracic and abdominal tumors,the negative effect of respiratory movement on radiotherapy persist throughout the whole process of radiotherapy.Deep inspiration breath-hold technique(DIBH)is a method of respiratory movement management in radiotherapy,which can reduce the negative effect of respiratory movement upon radiotherapy in the whole process of radiotherapy.Meantime,DIBH technique has its own characteristics and operation requirements compared with other respiratory movement management measures(such as 4D CT,gated technology and tracking,etc.).The aim of this review was to introduce the advantages,disadvantages and the application status of DIBH technique.
