The working group of "Establishment evidences and a standard protocol for contrast-enhanced FDG-PET/CT scans" of the Japanese Society of Nuclear Medicine (Dr. Munenobu Nogami Dr. Yuji Nakamoto Dr. Ukihide Tateishi Dr. Kazufumi Suzuki Dr. Setsu Sakamoto and Dr. Kazuhiro Kitajima) has planned to publish a handbook useful for doctors technologists and nurses working in the facilities considering new introduction of contrast-enhanced FDG-PET/CT scans.
Nihon Medi-Physics has produced/edited the handbook jointly with the working group to distribute to doctors who want it.

• *Contrast-enhanced FDG-PET/CT scan: A test that can obtain a PET-CT image with narrower location gap by sharing the bed with PET and CT devices placed coaxially.

The delivery PET committee a PET nuclear medicine subcommittee of the Japanese Society of Nuclear Medicine (chairperson: Dr. Tsunehiko Nishimura) was established to examine and resolve various problems regarding facilities using delivery PET agent. Nihon Medi-Physics has been supporting the subcommittee's activities as an observer from its establishment. The number of facilities registering as main members of the committee has increased from 16 to 77 from April 2008 to March 2012. During that time the committee: 1) conducted surveys by questionnaires on the current situation (first general survey: 93 facilities answered second survey on delayed imaging: 125 facilities answered); 2) produced and distributed the delivery PET agent user's handbook (first edition: 13000 copies revised edition: 8000 copies); 3) evaluated image quality during low dose imaging (visual and quantitative analysis of PET images by Miyazaki University); and 4) sponsored the delivery PET liaison council. Currently the committee has suspended its activities but will resume them as required when new drugs including an amino acid imaging agent (development code NMK36) obtains approval or when dementia diagnosis by FDG-PET is covered by national health insurance.
