摘要目的应用对比剂-强化数字化病人模型库,估计注射对比剂后标准腹部CT检查的辐射剂量。材料与方法在本研究的第二部分中,首先采用研究第一部分中所描述的技术,应用反映对比剂给药的病人特异性碘-时间曲线增强的大范围心脏-躯干模型。然后应用病人模型评定病人特定的器官剂量为标准腹部CT检查中的蒙特卡洛仿真时间函数。在这一假说研究中,器官剂量是指包括碘在内的单位质量组 Abstract Objective To evaluate the dose of standard abdominal CT examination after contrast agent injection by contrast medium-enhanced digital patient model library. Materials and Methods In the second part of this study, a broad-scale heart-trunk model with patient-specific iodine-time curves enhanced with contrast agent administration was first applied using the technique described in Part I of the study. Patient models were then used to assess patient-specific organ dose as a function of Monte Carlo simulation time in a standard abdominal CT scan. In this hypothesis study, organ dose refers to the unit mass group including iodine
