Combined positron emission tomography/computed tomography (PET/CT) has gradually advanced with the introduction of newly developed techniques. However, the recent status of imaging techniques (e.g., scanning range, availability of correction methods, and decisions on performing delayed scan) in oncologic PET/CT with F-fluorodeoxyglucose (F-FDG) in Japan is unclear. We conducted a nationwide cross-sectional survey to document F-FDG PET/CT protocols and clarify the recent status of imaging techniques for oncologic F-FDG PET/CT in Japan.
We conducted a web survey hosted by the Japanese Society of Radiological Technology between October and December 2017. The questionnaire included nine items on the demographics of the respondents, their scan protocols, and additional imaging to their routine protocols.
We received responses from 119 Japanese technologists who performed F-FDG PET/CT in practice. Almost all the respondents stated that the scanning range was from the top of the head to the pelvis or mid-thigh region. Newly developed techniques were used by fewer than half of the respondents. Most respondents performed additional imaging in consultation with physicians, such as delayed imaging (83%) or an extended scanning range for early imaging (55%).
Our survey helps in clarifying the recent state of oncologic F-FDG PET/CT imaging techniques in Japan. Given that F-FDG PET/CT practices most frequently performed additional imaging along with their routine scan protocol, the practice constitutes the most varied examination performed in Japanese nuclear medicine.
随着新开发技术的引入，正电子发射断层扫描/计算机断层扫描（PET/CT）已逐渐发展。然而，目前尚不清楚日本在使用氟脱氧葡萄糖（F-FDG）进行肿瘤PET/CT检查时成像技术的最新情况（例如扫描范围、校正方法的可用性以及是否进行延迟扫描的决策）。我们开展了一项全国性横断面调查，以记录F-FDG PET/CT方案，并阐明日本肿瘤F-FDG PET/CT成像技术的最新情况。
我们于2017年10月至12月开展了一项由日本放射技术学会主办的网络调查。问卷包括九个项目，涉及受访者的人口统计学信息、扫描方案以及常规方案之外的额外成像。
我们收到了119名在实际工作中进行F-FDG PET/CT检查的日本技术人员的回复。几乎所有受访者表示扫描范围是从头顶到骨盆或大腿中部区域。不到一半的受访者使用了新开发的技术。大多数受访者在与医生协商后进行额外成像，如延迟成像（83%）或扩大早期成像的扫描范围（55%）。
我们的调查有助于阐明日本肿瘤F-FDG PET/CT成像技术的现状。鉴于F-FDG PET/CT检查在常规扫描方案的基础上最常进行额外成像，该检查是日本核医学中开展的最多样化的检查。
