支气管肺癌术前正确评价有无胸壁侵犯对于制定手术计划及估计预后有重大价值。目前广泛应用CT与MR对肺癌的这一分期因素作出评估。本文应用呼吸中MR动态电影扫描检查肺癌的胸壁侵犯,该技术的优点是可以在呼吸状态下连续观察肿瘤与胸壁之间的相对运动。 Preoperative assessment of bronchial lung cancer with or without chest wall invasion is of great value for planning and estimating the prognosis. CT and MR are widely used to evaluate this stage of lung cancer. In this article, the chest wall invasion of lung cancer is examined by MR dynamic film scan during breathing. The advantage of this technique is that it can continuously observe the relative movement between the tumor and the chest wall under the condition of breathing.
