我们评估了人工智能聊天机器人ChatGPT在[18F]FDG PET/CT常见临床适应症中是否能够充分回答与患者有关的问题。方法：将13个关于[18F]FDG PET/CT的问题提交给ChatGPT。ChatGPT还被要求解释6个PET/CT报告（肺癌，霍奇金淋巴瘤）和回答6个后续问题（如肿瘤分期或推荐治疗）。要被评为“有用”或“适当”，回答必须符合核医学工作人员的标准。通过重新生成回答来评估不一致性。结果：25个任务中，92%的回答被评为“适当”，96%的回答被评为“有用”。对于16%的任务，重新生成的回答之间存在显著的不一致性。对于83%的敏感问题（如分期/治疗选择），回答被评为“富有同理心”。结论：在研究的设置中，ChatGPT可能能够充分替代核医学工作人员向患者提供的建议。提高ChatGPT的一致性将进一步提高可靠性。© 2023年核医学与分子影像学学会。

We evaluated whether the artificial intelligence chatbot ChatGPT can adequately answer patient questions related to [18F]FDG PET/CT in common clinical indications before and after scanning. Methods: Thirteen questions regarding [18F]FDG PET/CT were submitted to ChatGPT. ChatGPT was also asked to explain 6 PET/CT reports (lung cancer, Hodgkin lymphoma) and answer 6 follow-up questions (e.g., on tumor stage or recommended treatment). To be rated "useful" or "appropriate," a response had to be adequate by the standards of the nuclear medicine staff. Inconsistency was assessed by regenerating responses. Results: Responses were rated "appropriate" for 92% of 25 tasks and "useful" for 96%. Considerable inconsistencies were found between regenerated responses for 16% of tasks. Responses to 83% of sensitive questions (e.g., staging/treatment options) were rated "empathetic." Conclusion: ChatGPT might adequately substitute for advice given to patients by nuclear medicine staff in the investigated settings. Improving the consistency of ChatGPT would further increase reliability.© 2023 by the Society of Nuclear Medicine and Molecular Imaging.
