Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

AI model nearly halves false positive rates for lung cancer CT screenings
Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
A robot may soon be handling patients' ultrasounds in a Wisconsin health system
The machine will be operated remotely by a sonographer who has been trained to conduct remote ultrasound exams.
ED pivots to virtual radiology service, slashing CT turnaround times and lengths of stay
Syracuse, New York-based Upstate Medical University had previously relied on rad residents to handle initial reads, with attendings finalizing interpretation in the a.m.
COVID-induced neuroinflammation can last 2 years or longer, according to new PET data
These findings are important to consider with regard to patients’ long-term health, as chronic inflammation has been implicated in cognitive decline.
AI outperforms radiologists at predicting cancer treatment response based on imaging
These findings have the potential to change how treatment decisions are made in the future, researchers suggest.

M&A mergers and acquisitions business deal

GE HealthCare eyes IR guidance company, releases revenue results

Less than a week after ringing the Nasdaq opening bell to showcase its long-awaited independence, GE HealthCare has announced a first strategic acquisition is in the works.

New data on DCIS surveillance imaging has experts concerned

A concerning number of women do not follow through with recommended surveillance imaging following treatment for breast cancer.

Incoming American Association of Physicists in Medicine (AAPM) President Ehsan Samei, PhD, DABR, FAAPM, FSPIE, FAIMBE, FIOMP, FACR, chief imaging physicist for Duke University Health System and the Reed and Martha Rice Distinguished Professor of Radiology at Duke, is part of the team that developed the two specialized, medical-grade mannequin humans to test how much radiation NASA astronauts will receive on the Artemis missions to the Moon and beyond.

VIDEO: Radiology expertise used to create radiation astronaut phantoms for the Artemis I moon mission

Incoming AAPM President Ehsan Samei, PhD, FACR, chief imaging physicist for Duke University Health System, helped develop two specialized radiology phantom astronauts to measure how much radiation NASA astronauts will receive on future Artemis missions to the Moon and beyond.

Google Health develops AI models for more accurate gestational age estimation

The models do not require manual measurements from a sonographer to estimate GA. Instead, they are able to make use of ultrasound images and videos.

Winthrop P. Rockefeller Cancer Institute, University of Arkansas for Medical Sciences (USMS), is addressing health inequities in mammography using its Mammovan mobile breast imaging screening program. Gwendolyn Bryant-Smith, MD, explained how the program works. #RSNA #RSNA22

VIDEO: Bringing health equity to mammography and health screenings in Arkansas

Gwendolyn Bryant-Smith, MD, division chief of breast imaging and associate director for diversity, equity and inclusion at the Winthrop P. Rockefeller Cancer Institute, University of Arkansas, discussed how her center addressed health inequities in mammography.

Biological ‘brain age’ could help pave the way for more personalized medicine

AI-powered analysis can now assess cognitive decline by noting gaps in chronological versus biological “brain age.”

Vascular ultrasound findings offer clues into disability progression in MS patients

These findings were largely governed by biochemical and lifestyle factors, such as diet and physical activity. They were also found to have a greater influence on disability progression than aging.
