| 摘 要： | 目前PET-CT的应用已从简单定性分析发展到定量分析,靶组织体积对于肿瘤放射计划治疗生物靶区确定、肿瘤放射性核素治疗、组织脏器功能评价、受体亲和力计算和药代动力学研究等均有重要临床意义.靶组织体积的计算受PET图像采集模式,散射校正方法,衰减校正方法,重建技术,图像显示模式,正电子药物等因素影响.目前常采用的靶体积的计算方法有本底阈值法,最大值结合阈值法,本底与最大值结合阈值法等.本文阐述靶组织体积计算方法.

| Abstract: | The applications of PET-CT have developed from qualitative analysis to quantitative analysis. Target volume is important for tumor biological volume defining, tumor isotope therapy, organ function evaluation, acceptor affinity calculation, and pharmaceutical metabolic kinetics. Many factors work on the target volume calculation, such as PET image acquisition mode, scatter correction, attenuation correction, reconstruction method, image display mode, positron pharmacy. The commonly-used methods of target volume calculation are background-threshold, max threshold, and background-max threshold. In this article we will discuss about the methods of target volume calculation. |
