GE launches 64-slice PET/CT
GE Healthcare joined the ranks of believers in mega-slice PET/CT with the formal release of its Discovery VCT on the RSNA exhibit floor. The 64-slice hybrid, shown as a work in progress at the 2004 meeting, will compete with the Siemens biograph 64 and Philips Gemini GXL, both 64-slice PET/CT scanners launched one year ago.

Over the past several years, PET/CT has been widely adopted by the oncology community. Hybrids configured with 64-slice CTs may pave the way to a new cardiology market for this technology. GE's new Discovery VCT is being targeted specifically for cardiac applications.
Sixty-four-slice CTs show extraordinary detail in coronary CTA and promise to complement functional assessments of the heart possible with PET. Slowing the adoption of this technology, however, will be the lack of an optimal PET imaging agent for cardiac applications.
Rubidium currently supports myocardial perfusion studies with PET, but it is costly and cumbersome to produce. The radionuclide is created at clinical sites using a "generator" - radioactive strontium that rapidly decays into rubidium.
GE, a pioneer of hybrid imaging, has invested more than $160 million in the
research and development of hybrid imaging technology, according to the company, and holds 25 related patents. The company launched the era of fusion imaging in 1999 with its SPECT/CT Millennium VG Hawkeye. Its PET/CT Discovery LS followed two years later.
AI Facilitates Nearly 83 Percent Improvement in Turnaround Time for Fracture X-Rays
December 19th 2023In addition to offering a 98.5 percent sensitivity rate in diagnosing fractures on X-ray, an emerging artificial intelligence (AI) software reportedly helped reduce mean turnaround time on X-ray fracture diagnosis from 48 hours to 8.3 hours, according to new research presented at the Radiological Society of North America (RSNA) conference.
The Reading Room: Artificial Intelligence: What RSNA 2020 Offered, and What 2021 Could Bring
December 5th 2020Nina Kottler, M.D., chief medical officer of AI at Radiology Partners, discusses, during RSNA 2020, what new developments the annual meeting provided about these technologies, sessions to access, and what to expect in the coming year.
Can an Emerging PET Radiotracer Enhance Detection of Prostate Cancer Recurrence?
December 14th 2023The use of 68Ga-RM2 PET/MRI demonstrated a 35 percent higher sensitivity rate than MRI alone for the diagnosis of biochemical recurrence of prostate cancer, according to research recently presented at the Radiological Society of North America (RSNA) conference.
RSNA 2020: Addressing Healthcare Disparities and Access to Care
December 4th 2020Rich Heller, M.D., with Radiology Partners, and Lucy Spalluto, M.D., with Vanderbilt University School of Medicine, discuss the highlights of their RSNA 2020 session on health disparities, focusing on the underlying factors and challenges radiologists face to providing greater access to care.
Can AI Improve Detection of Extraprostatic Extension on MRI?
December 4th 2023Utilizing a deep learning-based AI algorithm to differentiate between diagnostic and non-diagnostic quality of prostate MRI facilitated a 10 percent higher specificity rate for diagnosing extraprostatic extension on multiparametric MRI, according to research presented at the recent RSNA conference.
Study: Regular Mammography Screening Reduces Breast Cancer Mortality Risk by More than 70 Percent
November 30th 2023Consistent adherence to the five most recent mammography screenings prior to a breast cancer diagnosis reduced breast cancer death risk by 72 percent in comparison to women who did not have the mammography screening, according to new research findings presented at the annual Radiological Society of North America (RSNA) conference.
