The universe of Japanese immigrants selected for this study consisted of a diverse group such as the kika nisei (returned second generation), the yobiyose (sponsored immigrant), and the gijutsu imin (technical immigrant). Each group possessed different characteristics. This present paper is limited in scope to the yobiyose and gijutsu imin because…

This synopsis outlines the Japanese guideline Version 1.0 for the data acquisition protocol of oncology FDG-PET/CT scans that was created by a joint task force of the Japanese Society of Nuclear Medicine Technology (JSNMT) and the Japanese Council of PET Imaging, and published in Kakuigaku-Gijutsu 29(2):195-235, 2009, in Japanese. The guideline aims at standardizing the PET image quality among facilities and different PET/CT scanner models by determining and/or evaluating the data acquisition condition in experiments using an IEC body phantom, as well as by proposing the criteria for human image quality evaluation using patient noise equivalent count (NEC), NEC density, and liver signal-to-noise ratio.

It is important to offer continuous medical service without interrupting everyone's various job functions at the Tama Numbu-Chiiki Hospitals in order to secure the quality and safety of home medical care to patients and their families. From 1998 up to the present, home intravenous hyper alimentation (home IVH) has been introduced by individually exchanging information that was based on items such as clinical case, doctor and caregiver in charge of the day, and introductory information. Five years have passed since we started an introduction of home IVH, and it appears that the medical cooperation of home IVH between the Minami-tama medical region and its neighboring area has been established. Then, we arranged an examination of the past 2 years based on the 57 patients who elected to choose home IVH instruction. Consequently, we created "home IVH introduction plan document" in standardizing a flow from home IVH introduction to post-hospital intervention. Since November of 2003, the plan document has been utilized and carried out to 5 patients by the end of February in 2004. This home IVH introduction plan document was able to clarify the role of medical person in connection with the patient. Therefore, we could not only share the information, but also could transfer medical care smoothly from the hospital to the patient's home.

Two kinds of Japanese guidelines for the data acquisition protocol of oncology fluoro-D-glucose-positron emission tomography (FDG-PET)/computed tomography (CT) scans were created by the joint task force of the Japanese Society of Nuclear Medicine Technology (JSNMT) and the Japanese Society of Nuclear Medicine (JSNM), and published in Kakuigaku-Gijutsu 27(5): 425-456, 2007 and 29(2): 195-235, 2009. These guidelines aim to standardize PET image quality among facilities and different PET/CT scanner models. The objective of this study was to develop a personal computer-based performance measurement and image quality processor for the two kinds of Japanese guidelines for oncology (18)F-FDG PET/CT scans. We call this software package the "PET quality control tool" (PETquact). Microsoft Corporation's Windows(™) is used as the operating system for PETquact, which requires 1070×720 image resolution and includes 12 different applications. The accuracy was examined for numerous applications of PETquact. For example, in the sensitivity application, the system sensitivity measurement results were equivalent when comparing two PET sinograms obtained from the PETquact and the report. PETquact is suited for analysis of the two kinds of Japanese guideline, and it shows excellent spec to performance measurements and image quality analysis. PETquact can be used at any facility if the software package is installed on a laptop computer.

This synopsis outlines the Japanese guideline Version 2.0 for the data acquisition protocol of oncology FDG-PET/CT scans that was created by a joint task force of the Japanese Society of Nuclear Medicine Technology, the Japanese Society of Nuclear Medicine and the Japanese Council of PET Imaging, and was published in Kakuigaku-Gijutsu 2013; 33:377-420 in Japanese. The guideline aims at standardizing the PET image quality among PET centers and different PET camera models by providing criteria for the IEC body phantom image quality as well as for the patient PET image quality based on the noise equivalent count (NEC), NEC density and liver signal-to-noise ratio, so that the appropriate scanning parameters can be determined for each PET camera. This Version 2.0 covers issues that were not focused on in Version 1.0, including the accuracy of the standardized uptake value (SUV), effect of body size together with adjustment of scanning duration, and time-of-flight (TOF) reconstruction technique. Version 2.0 also presents data acquired with new PET camera models that were not tested in Version 1.0. Reference values for physical indicators of phantom image quality have been updated as well.
