Is chest x-ray overused for patients on ventilation?
August 10, 2018 -- Many patients undergoing mechanical ventilation continue to receive daily chest x-rays, despite the publication of guidelines discouraging their use. On the positive side, the use of chest x-rays in these patients has declined from 2008 to 2014, according to an August 10 paper in JAMA Network Open.  Discuss
X-ray detects resurgence of black lung in coal miners
July 30, 2018 -- The prevalence of black lung disease has risen sharply among coal miners in the U.S., according to researchers who analyzed almost 50 years of radiographs. The trend reverses years of progress in reducing the prevalence of the disease, they note in a study published in the American Journal of Public Health.  Discuss
U.K. research could lead to flexible x-ray detectors
July 27, 2018 -- What if x-ray detectors were flexible enough to conform to patient anatomy? Would they produce better image quality or enable more accurate monitoring of radiation dose? It may not be a pipe dream. Researchers from the University of Surrey in the U.K. are working on a digital x-ray detector material that could be fabricated into flexible x-ray detectors.  Discuss
AI algorithm generates 'artificial' medical images
July 10, 2018 -- Researchers from Canada have developed an artificial intelligence (AI) algorithm capable of generating "artificial" x-ray images that look just like the real thing. The artificial images can be used to train other AI algorithms in analyzing real medical images.  Discuss
Will DR's positive outlook last past 2018?
June 11, 2018 -- The world market for digital radiography (DR), comprising fixed and mobile systems and DR retrofit kits, grew by approximately 5% in 2017 and is forecast to increase by a similar amount in 2018. But will the good times continue to roll for DR? Simon Harris of market research firm Signify Research takes a closer look.  Discuss

May 24, 2018 -- Which modality works best for diagnosing kidney stone disease, also known as urolithiasis: digital tomosynthesis, ultrasound, or the current reference standard of multidetector CT? It depends, according to a study published online May 17 in the European Journal of Radiology.  Discuss
AI can find, classify pleural effusions on chest x-rays
May 18, 2018 -- An artificial intelligence (AI) algorithm has shown promising results for finding and classifying pleural effusion on chest x-ray studies, potentially helping to speed up interpretation times and triage priority cases.  Discuss
Imaging aided patient care in 2015 Amtrak derailment
April 27, 2018 -- In 2015, an Amtrak train departing Philadelphia derailed, killing eight people and injuring 200. Local hospitals treated the injured, and imaging was a crucial part of patient care, according to a review published in the May issue of the American Journal of Roentgenology.  Discuss
Metal-free tomosynthesis spots success of hip implants
April 23, 2018 -- Chinese researchers found that digital tomosynthesis with a metal artifact reduction algorithm was better than either CT or conventional radiography for assessing the integration of hip implants with bone. Their findings were published in the May issue of the Journal of Arthroplasty.  Discuss
Augmented reality guides orthopedic surgery
April 20, 2018 -- Researchers have developed an augmented reality technique to visualize 3D virtual guidance lines directly on a patient during fluoroscopy-guided orthopedic surgery -- reducing procedure time and radiation, according to a study published in the April issue of the Journal of Medical Imaging.  Discuss
