Five years after the first survey the positron emission tomography (PET) council of the German Society of Nuclear Medicine (DGN) repeated a survey to re-evaluate the status of PET diagnostics in Germany based on the data of the year 2013.
A web-based questionnaire was used for gathering information retrospectively. Details regarding the physicians involved in PET operations, PET systems, and radiopharmaceuticals were also part of the survey as well as indications and number of studies. Furthermore, the role of PET and PET/CT within the diagnostic process was evaluated. In addition, official statistical hospital reports were analysed.
Responses from 52 sites were analysed. They reported a total of 38,350 PET studies in 2013. In the majority of cases PET was used in oncologic indications (87%). Further main applications were: neurology 6%, cardiology 1%, and inflammation 5%. University or other hospitals performed 85% of the studies. The portion of in-patients was 26%. Hybrid systems (56 PET/CT, 5 PET/MRT, and 2 stand-alone PET) were most frequently used for imaging. The radiotracers were labelled with F-18 in 90% of the studies, whereas Ga-68 was used in 9% and C-11 in 1%. Lung tumours were the most investigated tumour entity (40%), followed by malignant lymphoma (8%), tumours of the gastrointestinal tract (5%), and NET (5%). 20% of the 333 physicians hold a PET certificate awarded by the DGN. More than 50% of the facilities were certified according ISO9001, KTQ or QEP standard. The findings of nearly 60% of the oncological studies were discussed interdisciplinary in a tumour board. In federal statistical reports a 56% increase of in-patient PET operations during 5 years was found.
In Germany, a moderate increase (9% per year) of PET studies is observed, but compared with other industrialised countries PET is still less established.
在首次调查的五年后，德国核医学协会（DGN）的正电子发射断层扫描（PET）委员会基于2013年的数据再次进行了一项调查，以重新评估德国PET诊断的现状。
采用基于网络的调查问卷进行回顾性信息收集。关于参与PET操作的医生、PET系统和放射性药物的详细信息，以及适应症和研究数量也是调查的一部分。此外，还评估了PET和PET/CT在诊断过程中的作用。另外，对官方医院统计报告进行了分析。
分析了来自52个机构的回复。他们报告2013年共进行了38350例PET检查。在大多数情况下，PET用于肿瘤适应症（87%）。其他主要应用包括：神经病学6%、心脏病学1%、炎症5%。大学医院或其他医院进行了85%的检查。住院患者的比例为26%。混合型系统（56台PET/CT、5台PET/MRT和2台独立PET）最常用于成像。90%的检查中使用的放射性示踪剂标记有F-18，而9%使用Ga-68，1%使用C-11。肺部肿瘤是研究最多的肿瘤类型（40%），其次是恶性淋巴瘤（8%）、胃肠道肿瘤（5%）和神经内分泌肿瘤（5%）。333名医生中有20%持有DGN颁发的PET证书。超过50%的机构通过了ISO9001、KTQ或QEP标准认证。近60%的肿瘤学研究结果在肿瘤多学科讨论会上进行了跨学科讨论。在联邦统计报告中发现，住院PET操作在5年内增加了56%。
在德国，观察到PET检查有适度增长（每年9%），但与其他工业化国家相比，PET的应用仍不太成熟。
