AuntMinnie.com X-Ray Insider
Dear Digital X-Ray Insider,RSNA 2023 wrapped up in Chicago recently, with a bevy of digital x-ray studies presented at the meeting. We’ve featured one more here: an AI study conducted in Zambia testing an algorithm developed by Google to detect tuberculosis on chest x-rays. The model performed well, and you can read about the study in this issue’s featured article. As expected, AI studies took most of the top headlines from RSNA 2023. The mood at the meeting may have been summed up most succinctly by Sean Raj, MD, of outpatient radiology group SimonMed Imaging: “We’re going all in on AI,” he said, in a presentat...

AI improves x-ray reads for rads with varying experience
AI assistance can improve the detection accuracy of thoracic abnormalities on chest x-rays across radiologists with varying levels of expertise, according to a study published December 12 in Radiology. In a retrospective study, a commercially available algorithm (ChestView, v. 1.2.0, Gleamer) increased sensitivity for detecting all abnormalities on x-rays for all readers (thoracic radiologists, general radiologists, and radiology residents), according to a group of Gleamer consultants and clinicians at Cochin Hospital in Paris.“Our findings suggest that artificial intelligence assistance in chest radiograph interpretatio...

ChatGPT outperforms clinicians in post-negative test disease probability
ChatGPT-4 outperformed human clinicians in determining pretest and post-test disease probability after a negative test result involving chest radiographs and mammograms, according to a research letter published December 11 in JAMA Network Open.
Investigators led by Adam Rodman, MD, from Beth Israel Deaconess Medical Center in Boston did find, however, that ChatGPT-4 did not perform as well after positive test results.
“However, even if imperfect, probabilistic recommendations from [large language models] might improve human diagnostic performance through collective intelligence, especially if AI diagnostic aids can com...

Can ‘normal filtering’ AI save radiologists time?
AI algorithms appear to have clinical value based on detecting normal x-rays – that is, by flagging chest x-rays as normal versus abnormal, they may reduce reading times for radiologists, according to research presented recently at the RSNA meeting in Chicago.
In a session on chest imaging, scientists from AI developers Lunit and DeepTek.ai presented separate studies of AI algorithms configured to segregate patient chest x-ray images into those with significant clinical findings and those considered normal. In both cases, the algorithms ruled out a potentially significant number of reads.
“Actually, what we want to...

Don't get burned: Expert tips and tricks on MRI safety
How can MRI staff reduce the impact of radiofrequency-induced heating? Are tattoos and implantable medical devices safe? How can quenching be avoided? What are the special risks in 7-tesla MRI? A prize-winning RSNA 2023 exhibit addressed these and other questions.
"While we are familiar with medical safety and ethics principles when errors occur, the culture of blaming parties is still prevalent," noted Ana Paula Santos Lima, MD, assistant professor of radiology at the University of Washington, and colleagues. "Everyone makes mistakes; it's crucial to minimize risks. It's not always direct staff at fault."
System-wide vu...

New CT, MR scanners and AI top GE HealthCare highlights at RSNA 2023
CHICAGO -- GE HealthCare (GEHC) brought new CT and MRI scanners and a range of AI software applications to McCormick Place for RSNA 2023. CT In CT, GEHC shined the spotlight on its Revolution Ascend scanner, which was first introduced at ECR in March. With onsite detector upgrades, Ascend can be upgraded from a 20-mm coverage system for routine scanning to a 40-mm coverage system that delivers better low-contrast detectability, according to the vendor. The scanner also comes with True Enhance DL, an AI-based application that generates deep learning-based monochromatic-like images from a single-energy x-ray acquisition....

Deep-learning model measures shoulder kinematics on DDR
In this study, the goal was to develop a DL algorithm that can automatically determine the SHR, which normally requires complex and time-consuming manual calculations by clinicians and thus is rarely performed in routine clinical cases, he said.The prototype DL algorithm was trained on 447 images from 267 cases to recognize the humerus and scapula positions, calculate the required scapulothoracic and glenohumeral angles, and thus determine the SHR across the complete range of abduction.The performance of the algorithm was then evaluated by comparing its measurements with manual human reader measurements on a unique data se...

AI assist for x-ray reads serves nonradiologists well in the ED
CHICAGO -- German researchers are testing ways to support nonradiologists in interpreting chest x-rays in emergency settings using an AI assistant.Presenting the research on November 28 at RSNA 2023, Jan Rudolph, MD, from the department of radiology at University Hospital LMU Munich said nonradiologists can significantly benefit from AI assistance in emergency-related chest x-ray analysis.“If you go to the periphery, to smaller hospitals in the periphery, there's basically the duty doctors from internal medicine or surgery departments that have to analyze the chest x-rays,” Rudolph explained. “So we were thinking and...
