To establish a feasible and practical methodology for harmonization of FDG-PET, we have investigated quantitative physical performance of recent clinical PET scanners (23 scanners) using the NEMA image quality phantom. Compared with the previous phantom data (13 scanners) acquired in the early 2000s, the current phantom data showed better contrasts of small spheres even with a smaller number of coincidence counts. This result suggests that clinical PET image quality and small lesion detectability might have been significantly improved in the past 10 years. Based on the data acquired in this working group, we are planning to update the standard phantom test methodology and harmonizing criteria for FDG-PET.

为了建立一种可行和实用的方法来协调FDG-PET，我们使用NEMA图像质量幻象研究了最近的临床PET扫描仪(23台扫描仪)的定量物理性能。与21世纪初获得的先前幻影数据(13台扫描仪)相比，当前的幻影数据显示，即使巧合计数较少，小球体的对比度也更好。这一结果表明，临床PET图像质量和小病变检出率可能在过去10年有了显著提高。根据该工作组获得的数据，我们计划更新FDG-PET的标准模体测试方法和协调标准。

PURPOSE We developed and validated the accuracy of a method to calculate the arterial input function (AIF) from PET images only, without the need for the arterial blood sampling, in the absolute quantitation of functional parametric values in 15O- gas PET examinations. METHODS We extended the method reported by Iguchi et al. (2013) to derive the arterial input function, thus absolute quantitative functional parametric images of cerebral perfusion and oxygen metabolism by a reference tissue approach. We compared shapes of the AIF and reproducibility of the absolute functional values. Existing test data that were carried out with the continuous arterial blood sampling were used for this study. RESULTS The estimated AIF shapes agreed well with those estimated from the continuous arterial blood sampling. The error range of the absolute quantitative values was approximately ±20%, with a fairly well reproducibility in the relative values being less than 3%. CONCLUSION The AIFs by this method were reproducible. Although the absolute quantitative values varied depending on the assumed functional values in the reference region in individual cases, the relative images showed fairly good agreement with the results from the standard technique that employed the arterial blood sampling. The present technique may provide significant contribution to clinical examination.
目的:我们开发并验证了一种仅从PET图像计算动脉输入函数(AIF)的方法的准确性，而不需要动脉血液采样，在15O-气体PET检查中功能参数值的绝对定量。方法:我们扩展了Iguchi et al.(2013)的方法，推导出动脉输入函数，从而通过参考组织法获得脑灌注和氧代谢的绝对定量功能参数图像。我们比较了AIF的形状和绝对功能值的再现性。本研究使用的是连续动脉采血的现有检测数据。结果:估计的AIF形状与连续动脉采血估计的形状吻合良好。绝对定量值的误差范围约为±20%，相对值的重现性较好，小于3%。结论:该方法制备的aif具有良好的重复性。虽然绝对定量值在个别情况下根据参考区域的假设功能值而变化，但相对图像显示与采用动脉血液采样的标准技术的结果相当吻合。本技术对临床检查有重要意义。

This survey was performed in order to investigate the incidence of adverse reactions to radiopharmaceuticals in FY2019 in Japan. It was based on responses to questionnaires sent to nuclear medicine institutions. Replies were obtained from 1,003 institutions out of 1,213 to which the questionnaire had been sent. A total of 1,037,568 radiopharmaceutical administrations were reported. Eighteen cases of adverse reactions were reported. The incidence of adverse reactions per 100,000 cases was 1.7. No case of defective products was reported.
