X-ray

Medical X-rays have mostly converted from film, to computed radiography (CR) that used individual plates to record each X-ray digitally that then had to be uploaded into a PACS, to what is the standard-of-care today with digital radiography (DR). DR X-ray which allows immediate digital transfer of images into a PACS for immediate review. X-rays are used to diagnose fractures, bone abnormalities, lung pathologies and tumors, as well as monitor pediatric growth, plan for surgery and treat oncology patients during radiation therapy. More detailed anatomical imaging, especially soft tissue imaging, is usually sent for advanced imaging with CT or MRI. X-ray, especially mobile DR systems, are a primary use case for artificial intelligence (AI) integration.

A ‘powerful’ tool: Commercially available AI significantly outperforms radiologist reads for trauma imaging

The software was put to the test on nearly 5,000 trauma radiographs, assessing for the presence of fractures, dislocations, elbow effusions and focal bone lesions. In some cases, it outperformed radiologists by as many as 82 points.

Algorithm spots enteric tube misplacement on x-ray with great accuracy

The model was externally validated using more than 1,500 radiographs with real-world incidence of critically misplaced tubes. 

COVID ventilation complications

Life-threatening barotrauma common in intubated COVID patients, trackable by chest X-rays

Radiologists involved in the care of these patients should be especially vigilant in identifying the signs of complications, experts cautioned in a new Clinical Imaging research paper.

AI software approved for use on adult chest X-rays shows promise for pediatric population

In a sampling of 2,273 chest radiographs of kids aged 2 to 18-years-old the AI-based software achieved diagnostic accuracies ranging from 86% to 96.9% for detecting a myriad of pathologies.

Many clinicians flouting X-ray-first guidelines for ankle imaging

Established clinical guidelines hold that patients presenting with ankle issues should not receive advanced imaging ahead of standard radiography. New research shows a substantial proportion of ordering clinicians sending these patients straight to MRI anyway.
