Effective therapeutic treatment with in vivo administered radioactivity depends on the localization of appropriate concentrations in tissues to be treated. Accurate assessment of both diagnostic and therapeutic concentrations of radiopharmaceuticals is the goal of quantitative SPECT imaging. The technology of SPECT imaging has significantly improved over the past 5 years, and routine quantitation for SPECT users may not be far away. The four operational steps by quantitative SPECT imaging are described, along with technical factors that require further development before it can be used routinely.
体内放射性给药的有效治疗取决于在待治疗组织中适当浓度的定位。准确评估放射性药物的诊断和治疗浓度是定量单光子发射计算机断层显像（SPECT）成像的目标。在过去5年中，SPECT成像技术有了显著改进，SPECT用户的常规定量可能也为期不远。本文描述了定量SPECT成像的四个操作步骤，以及在其能够常规使用之前需要进一步发展的技术因素。
