目的 心跳引起的冠状动脉运动是影响其剂量评估精度的主要因素.本研究应用心电门控(electrocardiography-gated,ECG-gated) 4D-CT测量冠状动脉主要分叉口随心跳运动的位移,并依此确定胸部肿瘤放疗中冠状动脉分叉口的外放边界.方法 选取2015-04-01-2017-04-30山东大学附属山东省肿瘤医院怀疑有心脏疾患的女性患者37例为研究对象.所有患者均接受吸气屏气下ECG-gated 4D-CT增强扫描,并确诊无器质性病变.分别选取冠状动脉左主干分叉口(left main coronary artery bifurcation,LM)、第一对角支分叉口(the first diagonal branch bifurcation,D1)、第二对角支分叉口(the second diagonal branch bifur...

OBJECTIVE Cardiac motion-induced the coronary movement is the main factor affecting the accuracy of dose evaluation of coronary artery. This study was to measure the displacements and calculate the margin of the coronary artery main bifurcations utilizing electrocardiography-gated(ECG-gated) 4D-CT for thoracic tumor radiotherapy.METHODS From 2015 April 1th to 2017 April 30th in the Shandong Cancer Hospital Affiliated to Shandong University and Shandong Provincial Hospital, a total of 37 female patients who had a clinical suspicion of heart dise...
