AIM

The working group on positron emission tomography (PET) of the DGN (German Society of Nuclear Medicine) initiated this first survey to collect and analyse information on the practise of PET in Germany in the year 2008.

METHODS

A questionnaire was sent to PET performing facilities (medical practices, hospitals, university hospitals and others) for retrospective data acquisition. Details regarding the equipment and examination procedures were examined as well as indications and number of studies. In addition, the role of PET within the diagnostic process was evaluated.

RESULTS

Responses from 65 sites were analysed. Their technical equipment consisted of 77 PET scanners (40 of them were combined PET/CT devices). About 63500 PET studies had been performed with 86% in the field of oncology, 8% in neurology and 3% in cardiology. The radiotracers were labelled with 18F in 91% of the studies, whereas 68Ga was used in 4% and 11C in 3%. The analyses revealed lung tumours as the most investigated tumour entity, followed by malignant lymphoma, tumours of the gastro-intestinal tract and prostate cancer (about 14000, 6000, 5000 and 2000). Corresponding to the new scanners and software procedures, the number of studies with attenuation correction by CT was high (68%) and nearly all studies were reconstructed iteratively (99%). The PET images were analysed quantitatively in the majority of cases (91%). The clinical reports, which included image documentation for the greater part, were posted regularly within 3 days. However, in 70% of the sites electronic transfer possibilities were used additionally to speed up the diagnostic process. The high standard of quality was demonstrated by the fact, that 40 facilities were engaged in a tumour board. Further on, one third of the physicians had gained a PET certification awarded by the DGN.

CONCLUSION

Relative to the high general standard of diagnostic instrumentation in Germany, PET is less established, in particular when compared with other industrialised countries such as USA and Switzerland.

目的

德国核医学协会（DGN）正电子发射断层扫描（PET）工作组开展了首次调查，以收集和分析2008年德国PET实践的相关信息。

方法

向PET检查机构（医疗诊所、医院、大学医院等）发送问卷以进行回顾性数据采集。调查了设备和检查程序的详细信息以及检查的适应症和数量。此外，还评估了PET在诊断过程中的作用。

结果

分析了来自65个机构的回复。其技术设备包括77台PET扫描仪（其中40台是PET/CT一体机）。共进行了约63500例PET检查，其中86%用于肿瘤学领域，8%用于神经学领域，3%用于心脏病学领域。91%的检查使用的放射性示踪剂为18F标记，4%使用68Ga，3%使用11C。分析显示，肺部肿瘤是研究最多的肿瘤类型，其次是恶性淋巴瘤、胃肠道肿瘤和前列腺癌（分别约为14000例、6000例、5000例和2000例）。与新型扫描仪和软件程序相对应，采用CT进行衰减校正的检查数量很高（68%），几乎所有检查都采用迭代重建（99%）。大多数情况下（91%）对PET图像进行了定量分析。临床报告大多包含图像记录，通常在3天内发出。然而，70%的机构还额外使用了电子传输方式以加快诊断过程。40个机构参与了肿瘤病例讨论会，这一事实证明了高质量标准。此外，三分之一的医生获得了DGN颁发的PET认证。
