Preview: CT vendors crank up low-dose solutions
Protocols that get the most from every x-ray and high-tech algorithms that delete noise will drive CT at this year’s show.

GE’s ASIR (adaptive statistical iterative reconstruction) technology will take center stage as a means to reduce patient x-ray dose by up to 50% on the company’s Discovery CT750 HD and LightSpeed VCT. ASIR is now running on more than 450 scanners worldwide, cutting dose for more than 10,000 patients per day, according to the firm. GE competitors will make similar claims for their proprietary versions of iterative reconstruction, Siemens’ IRIS and Philips’ iDOSE.
Toshiba will bring to RSNA 2010 its Adaptive Iterative Dose Reduction (AIDR) for high-end CT dose reductions. The company showcased the product for cardiac CT exams done on its Aquilion One, Aquilion Premium, and all its 64-detector row CT scanners at the European Society of Cardiology Congress in Stockholm, Sweden, in late August. AIDR remains a work-in-progress in the U.S., pending FDA clearance. It will be accompanied by Target CTA, a cardiac protocol for reducing dose on the Aquilion One. The company will also spotlight its work-in-progress 160-detector row spiral scanning technology on the Aquilion One and Aquilion Premium, allowing full chest, abdomen, and pelvis scans in less than five seconds.
GE will port developments in iterative reconstruction for CT to nuclear medicine with the unveiling of its SharpIR, an iterative reconstruction enhancement compatible with the company’s Discovery PET/CT 600 scanners. The CT version, ASIR, will be ported also to PET/CT and SPECT/CT scanners in the GE portfolio to minimize CT dose.
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.
