AI's impact on false-positive mammograms, breast cancer screening performance
Computer-aided detection (CAD) software for mammography has been available for decades but has traditionally been hampered by a high number of false-positive marks. AI software based on deep-learning algorithms is showing promise, however, for helping to improve specificity in screening mammography and other breast imaging modalities.
Just over 40.5 million mammograms were performed in the U.S. in 2023, according to Mammography Quality Standards Act (MQSA) national statistics. Although mammogram is the most widely used screening modality, a known problem is that 9.5% of the 10% of women contacted for further testing after...

Is human-AI ‘symbiosis’ the path forward in chest radiography?
Human-AI symbiosis – rather than totally autonomous AI – should be the current goal for AI in chest radiography, according to an editorial published January 23 in Radiology.“In the coming years, radiologists will find themselves working in a reimagined diagnostic cockpit, increasingly interpreting chest radiographs and other imaging studies in symbiotic partnership with AI,” proposed lead author Warren Gefter, MD, of the University of Pennsylvania in Philadelphia, and colleagues.To achieve this vision, radiologists will need to apply the goals of “human-centered AI” and symbiosis to the design and implementatio...

Few ‘surprise’ patient bills are from radiologists, study finds
Out-of-network billing by radiologists – often referred to as “surprise billing” – dropped significantly beginning in 2007 and imaging claims are now almost completely in network, according to a recent study.
In an analysis of billing trends, the rate of out-of-network (OON) imaging claims declined from 12.6% in 2007 to 1.1% in 2021, with the decline occurring broadly across imaging modalities, noted lead author Jay Parikh, MD, of the University of Texas MD Anderson Cancer Center in Houston.
“This consistent decline over time likely reflects in part effective persistent good-faith negotiations between radiology...

Deep learning combines breast imaging data to predict cancer prognosis
Deep-learning models could have potential as predictive tools for breast cancer prognosis, a study published January 17 in Clinical Breast Cancer has found.
A team led by Junqi Han, MD, from the Affiliated Hospital of Qingdao University in China found that its model combining data from mammography images, ultrasound images, and other characteristics performed well in predicting disease-free survival of breast cancer.
“The combination of mammography and ultrasound images improved… performance for predicting breast cancer prognosis compared with single medical imaging modalities,” Han and colleagues wrote.

Medical students gain confidence in radiology boot camp
Undergraduate medical students were eager to participate in an elective one-week radiology boot camp, with participants reporting the experience boosted their radiology knowledge but also their confidence in other specialties, according to a recent study.
Radiologists at McMaster University in Hamilton, Ontario, surveyed students before and after the course, with findings suggesting the format could help meet increasing demands for radiology content in undergraduate training, noted lead author and medical student Levi Burns, and colleagues.
“Focusing on radiology skills for nonradiology rotations was a successful strat...

AI may help plan new treatment in scoliosis patients
An AI model for x-ray imaging could help clinicians plan treatment other than spinal fusions in patients with adolescent idiopathic scoliosis, according to research published January 14 in PLOS One.
The study proposes a machine learning-based tool for planning anterior vertebral body tethering (AVBT), an emerging minimally invasive surgical treatment, noted first author Ausilah Alfraihat, a PhD student at Drexel University in Philadelphia, PA, and colleagues.
“The current model has potential to serve as a valuable clinical tool, providing insight into the optimal timing of intervention and surgical planning parameters,...

The role of cone-beam computed tomography in the radiographic evaluation of obstructive sleep apnea: A review article
Imaging Sci Dent.2023 Dec;53(4):283-289.
doi: 10.5624/isd.20230119.
Epub 2023 Nov 6.
Abstract
The apnea-hypopnea index is widely regarded as a measure of the
severity of obstructive sleep apnea (OSA), a condition characterized by
recurrent episodes of apnea or hypopnea during sleep that induce airway
collapse. OSA is a catastrophic problem due to the wide range of health
issues it can cause, including cardiovascular disease and memory loss.
This review was conducted to clarify the roles of various imaging
modalities, particularly cone-beam computed tomography (CBCT), in the
diagnosis of ...

Workplace violence ‘extremely high’ in radiologic sciences
More than 60% of diagnostic radiology and radiation therapy staff experience workplace violence, according to a study published January 9 in Radiography.
Risk factors for workplace violence include intoxicated patients, staff stress, long patient waiting times, overcrowded environments, and inadequate staff and security measures, wrote lead author Krushi Shah, of Curtin University in Perth, Australia. The authors called for implementing strategies to reduce risk.
“The most common coping strategy [we found in our review] was doing nothing, which is concerning,” they noted.
Workplace violence is a significant issue in...
