PET unit installed at private hospital in Hawaii
Japanese photomultiplier tube supplier Hamamatsu Photonics is pursuing the research side of positron emission tomography with a new PET camera the company has installed at an imaging center in Hawaii. Hamamatsu has received Food and Drug Administration clearance for the camera, called SHR-22000, but at present has no plans for a commercial rollout of the system.
Hamamatsu introduced the camera at a September press conference in conjunction with Queens Medical Center of Honolulu. Hamamatsu and the hospital are collaborating in the operation of Queens PET Imaging Center, which is the first PET imaging facility in Hawaii. The Hamamatsu camera is one of only two produced by the company; the second is in Japan.
The 32-ring camera uses 22,000 detectors to produce images with spatial resolution in the 3.5-mm range. The cameras rings allow for a 20-cm field-of-view. Hamamatsu worked with Hitachi on the scanner: Hamamatsu designed the unit, and Hitachi built it (SCAN 5/27/98). Hitachi is working to refine software for the camera and develop an image processing workstation.
Hamamatsu, of Hamamatsu, Japan, was established in 1953 and develops and manufactures photomultiplier tube technology that it supplies to gamma camera OEMs. The firm is not planning to begin a market push for its scanner, but will focus instead on research, particularly in the field of brain studies, according to Whit Athey, an attorney with C.L. McIntosh & Associates in Washington, DC. Athey is the author of Hamamatsus 510(k) application.
My understanding is that at least initially (the company) is not planning to make a commercial product, since theres not much demand for PET, Athey said. Theyre more interested in research.
Queens Medical Center plans to do brain studies with the camera, as well as other investigation into alternative uses for PET imaging. Research scans are funded by private money provided by the hospital and Hamamatsu.
A Victory for Radiology: New CMS Proposal Would Provide Coverage of CT Colonography in 2025

ACR Collaborative Model Leads to 35 Percent Improvement with Mammography Positioning Criteria
July 1st 2024Noting significant variation with facilities for achieving passing criteria for mammography positioning, researchers found that structured interventions, ranging from weekly auditing of images taken by technologists to mechanisms for feedback from radiologists to technologists, led to significant improvements in a multicenter study.
New Study Shows Non-Radiologists Interpreting 28 Percent of Imaging for Medicare Patients
June 28th 2024While radiologists interpreted approximately 99 percent of all non-cardiac CT, MRI and nuclear medicine studies in hospital and emergency department settings for Medicare beneficiaries, new research shows significantly less radiologist review of cardiac imaging and office-based imaging.
