Northwestern, Dell develop LLM for chest x-ray interpretation
Dell Technologies and Northwestern Medicine are collaborating on a generative multimodal large language model (LLM) for the interpretation of chest x-rays.
Working with Dell's AI Innovation Lab, Northwestern Medicine has designed and tested workflow software prior to deploying them into their own IT environment where they achieved the multimodal LLM that produced draft x-ray reports to aid in physician decision-making, Dell said.
The research and development team within Northwestern Medicine Information Services is led by Mozziyar Etemadi, MD, PhD, medical director of Northwestern Medicine Advanced Technologies, accordin...

Can AI help chest DDR achieve clinical adoption?
Chest dynamic digital radiography (DDR) may have received a boost toward clinical use in patients with lung disorders, with researchers developing AI to perform time-consuming analysis involved in the technology, according to researchers in New York City.
A group at Mount Sinai Hospital developed a “pipeline” of convolutional neural networks (CNNs) to analyze lung areas in DDR image sequences from patients. The model performed well enough to act as a surrogate to standard pulmonary function tests, they found.
“Our findings add to growing evidence suggesting DDR as a potential [pulmonary function test] surrogate,”...

A muon collider could revolutionize particle physics —if it can be built
Young people supposedly enjoy the luxury of time, but perhaps not if they’re particle physicists. For decades, physicists have peered into the universe’s inner workings by smashing subatomic particles together at ever higher energies. But the next highest energy collider may not be built for 50 years. And Tova Holmes, 34 and a particle physicist at the University of Tennessee, Knoxville, worries her career could slip away before she ever sees such a machine. “I will be definitely not still working, possibly not alive,” Holmes says.
That’s one reason she and dozens of her contemporaries are pushing to develo...

Radiologists, RTs, and the art of forensic imaging
Ever since Wilhelm Conrad Roentgen's discovery of x-rays in 1895, the field of medical imaging has continued to expand across a multiplicity of applications, and one of the most fascinating is its use as a forensic tool to determine the causes of trauma, both in living and deceased individuals.
Forensic radiologists and radiologic technologists apply their expertise to imaging exams -- typically x-ray and CT -- intended to illuminate signs of trauma. So how do these experts approach forensic radiology? AuntMinnie.com spoke to two experts about the state of the specialty.
Training is key
What is forensic radiology? Put s...

Training technique in AI helps preserve patient privacy
The privacy of patient data in AI models trained on chest x-rays can be guaranteed – importantly, without significantly reducing the accuracy of models on large “real-world” data sets, according to a study published March 14 in Communications Medicine.
A team in Germany used an approach called “differential privacy” when training large-scale AI models and then evaluated its effects on model performance. They found high accuracy was attainable, despite the stringent privacy guarantees, noted lead authors and PhD students Soroosh Tayebi Arasteh, of University Hospital RWTH Aachen, and Alexander Ziller, of the Tech...

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...

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).
