The aim of the present study was to clarify the routine protocols and the frequency of added or omitted imaging on nuclear medicine imaging in Japan. A nationwide survey on routine protocols and current state of added or omitted imaging in major nuclear medicine imaging were performed for Japanese nuclear medicine technologist. The survey showed that the routine protocols were almost 100% fixed, some of the routine protocols were found to be useful and percentage of imaging techniques such as single photon emission computed tomography/computed tomography that increased patient burden and reduced through put were low. Furthermore, the survey showed that additional or omission imaging were frequently performed on bone scintigraphy and positron emission tomography and added or omitted judgements were often depend upon the rule of thumb by nuclear medicine technologist. In this study, we have concluded that the quality of examination and the diagnosis might depend on the knowledge of nuclear medicine technologist, performed added or omitted imaging.
本研究的目的是阐明日本核医学成像的常规方案以及增加或省略成像的频率。针对日本核医学技术人员，就主要核医学成像的常规方案及增加或省略成像的现状开展了一项全国性调查。调查显示，常规方案几乎100%是固定的，部分常规方案被认为是有用的，而诸如单光子发射计算机断层扫描/计算机断层扫描等增加患者负担并降低 throughput 的成像技术的比例较低。此外，调查表明，骨闪烁显像和正电子发射断层扫描经常进行额外或省略成像，增加或省略的判断往往取决于核医学技术人员的经验法则。在本研究中，我们得出结论，检查和诊断的质量可能取决于进行增加或省略成像的核医学技术人员的知识水平。
