Image perception: Are radiologists akin to MLB batters?
A radiologist’s perception when viewing a complex MR image may be akin to a Major League Baseball (MLB) batter reading the stitches on a fastball, according to researchers exploring exactly how diagnostic interpretations are made.
The baseball metaphor works because eye-tracking studies have shown that radiologists are able to discriminate between normal and abnormal stacks of 26 T2-weighted images from prostate MRI in as little as 48 milliseconds per section, said neuroscientist Robert Alexander, MD, of SUNY Downstate Health Sciences University in Brooklyn, in an interview with AuntMinnie.com.

‘Smart’ fiber-optic cables on the sea floor will detect earthquakes, tsunamis, and global warming
Everybody in Portugal knows the date: 1 November 1755. It was All Saints’ Day, with candles lit in homes to honor ancestors. Then the earthquake struck, cracking the streets of Lisbon open and sparking a firestorm. A tsunami engulfed the port, and tens of thousands died. Even now people are aware of the threat— from a nearby seafloor junction where the grinding tectonic plates of North America, Eurasia, and Africa meet—says José Barros, who retired recently from a senior role at ANACOM, Portugal’s telecom regulator. “We are always having those thoughts—and fears.”
Soon Lisbonites may be able to count o...

VA Benefits Now Available to Millions of Veterans
VA health care benefits are now available to millions more veterans in one of the largest expansions of coverage in the U.S. The inclusion of significantly more veterans compared to past bills comes at the direction of President Joe Biden.
Veterans Who Now Qualify
Veterans of the Vietnam War, the Gulf War, Iraq, Afghanistan, the Global War on Terror or any other combat zone after 9/11.
Service members who were exposed to any toxins or other hazards during service at home or abroad.
Those who were never deployed but were exposed while training or on active duty in the U.S.
Benefits cover exposure to asbesto...

AI flags rare humeral bone tumors on chest x-rays
An AI algorithm can help identify rare tumors on upper arm bones in patients undergoing chest x-rays – findings not typically identified in daily reading practice, according to an article published March 6 in Radiology: Artificial Intelligence.
The algorithm improved the ability of radiologists to identify the tumors, which are located at the periphery of chest x-ray images, noted lead authors Harim Kim, MD, and Kyungsu Kim, PhD, of the Samsung Medical Center in Seoul, South Korea.
“Radiologists showed improved performance with assistance of the AI program, particularly in terms of sensitivity and accuracy. We expect...

Dark-field chest x-ray takes step forward
German developers of dark-field chest x-ray appear to have overcome a technical limitation of the technology – namely, adjusting for photon scattering caused by interferometers used in the experimental system.
This scattering is picked up by the system’s detector (so-called “detector cross talk”) and leads to unwanted artifacts on patient chest x-rays, noted study lead and doctoral candidate Theresa Urban, of the Technical University of Munich, and colleagues. Ultimately, the group described a method to correct the phenomenon to produce better images.
“With the corrections presented here … the obtained dark-f...

Study calls for improvement of commercial AI algorithms
In this study, the researchers aimed to externally validate the technology in a prospective observational study in patients who were scheduled for chest x-rays. They obtained a radiologist’s report for each patient (considered the gold standard) and subsequently compared the findings to the AI algorithm’s findings on the same reports.Image of patient (upper-left) in which, according to the radiologist's report, there is only consolidation, but the algorithm detects an abnormal rib (upper-right), consolidation (lower-left), and two nodules (lower-right). It is worth noting the confusion of a consolidation with mammary t...

‘Doing something for the real world’: how 1,000 UK schoolkids helped crack a crystals conundrum
When citizen science in school labs ended up in a particle accelerator, the results advanced our understanding of how crystals form – with a positive impact on the future of medicine, materials science and moreGry Christensen was a 15-year-old year 11 student when she took part in a “citizen science” project to understand how the different crystals in mussel shells form. But unlike most school experiments, the samples that she and her 1,000 fellow secondary school pupils prepared were then blasted by scientists in a particle accelerator using X-rays 10bn times brighter than the sun.“It was a bit of an eye opener,...

ECR: Implementing imaging referral guidelines shows positive impact
Implementing imaging referral guidelines not only supports value-based radiology but makes it easier to communicate with patients about low-value services, according to findings presented February 29 at ECR 2024.
In an open forum, Yi Xiang Tay, of Singapore University Hospital's radiography and diagnostic imaging department, shared his team's research. It was the endnote of a series of sessions focused on optimizing radiology services.
"Low-value imaging procedures result in an ineffective allocation of resources and imposes potential danger," Tay said. "This includes increasing patient costs, the rise of cancer, and inc...

Can radiologists ’ eye-tracking data enhance AI?
Integrating eye-tracking data that map how radiologists interpret x-rays into deep learning AI algorithms could be key to developing more “human-centered” AI, according to a recent study.
A group led by researchers in Lisbon, Portugal, conducted a systematic literature review of the use of eye gaze-driven data in chest x-ray deep learning (DL) models and ultimately proposed improvements that could enhance the approach.
“There is a clear demand for more human-centric technologies to bridge the gap between DL systems and human understanding,” noted lead author José Neves, of the University of Lisbon, and colleague...

Radiologists ‘compete’ on chest x-rays reads with and without AI
In a study described as a “competition between radiologists,” participants tasked with identifying abnormal findings on chest x-rays performed better with AI assistance than without AI assistance – though not by much and not in all cases, according to a group in Nanjing, Jiangsu, China.
Significantly, however, AI assistance allowed participants to cut reading times by nearly half, noted lead author Lili Guo, MD, of Nanjing Medical University, and colleagues.
“This competition demonstrated the value of AI in detecting and localizing many pathologies in chest radiographs by simulating the real work situations of ra...
