Algorithm identifies misfiled chest x-rays in PACS
July 8, 2013 -- The adoption of PACS hasn't eliminated the problem of lost x-ray films, as any healthcare facility knows. But Japanese researchers believe they've found an answer through a computer algorithm that locates misfiled chest radiographs based on unique anatomical data, which they call "biological fingerprints," found in each x-ray.
H7N9 bird flu pneumonia scans show common imaging findings
July 2, 2013 -- A new bird flu strain known as influenza H7N9 appeared in China this year and quickly took a number of human victims. An article in Radiology published on Tuesday includes some of the first radiologic images of the effects of the virus, revealing typical patterns of progression and regression on CT scans and radiographs of the chest.
U.S. updates x-ray rules for black lung program
July 2, 2013 -- The U.S. government has finalized new rules that allow images from digital radiography (DR) systems to be used for claims filed under its program for screening coal miners for black lung disease. The program's technical specifications haven't been updated since 1980, despite the rising use of DR.
Could chest tomo be a first-line lung cancer screening tool?
June 5, 2013 -- With all the attention being paid to CT lung cancer screening, what about x-ray? Italian researchers believe that radiology's oldest modality could be revived as a screening tool with a technological twist -- digital tomosynthesis. They describe their findings in the June edition of the Journal of Thoracic Oncology.
A radiologist reflects on the Boston Marathon bombings
May 16, 2013 -- Monday, April 15 -- Patriots' Day in Boston -- started much like any other day for radiologist Dr. Robert Ward of Tufts Medical Center. But it turned out to be anything but normal after two bombs exploded at the end of the Boston Marathon, sending dozens of injured people to Tufts with battlefield-like injuries.
CAD, bone suppression find more lung nodules on chest x-ray
May 7, 2013 -- At the cost of more false positives, the combination of computer-aided detection (CAD) and electronic bone suppression can help radiologists improve detection rates for pulmonary nodules on chest radiographs, according to research published in the May issue of the American Journal of Roentgenology.
Record label swaps x-ray film for traditional vinyl
March 15, 2013 -- If you're tired of reading x-rays, how about spinning them instead? Old medical x-ray films were literally pressed into service to form limited-edition discs of a new single from record label Third Man Records, founded by Jack White of the band the White Stripes.
Airport security scanners carry some radiation risk
March 8, 2013 -- VIENNA - Airport security scanners are safe for individuals, but when their effects are considered collectively, there is still a risk of cancer developing due to the machines, ECR 2013 delegates learned at a standing-room-only session on Thursday afternoon.
Mercy Ships offers volunteer opportunities for physicians
February 20, 2013 -- Radiologists have much to offer as volunteer physicians for Mercy Ships, a nonprofit organization that provides much-needed basic medical care to people in developing nations. In a recent article in the American Journal of Roentgenology, a U.S. radiologist who served on the Africa Mercy described his experiences.
Imaging vendors target China's rural healthcare market
February 7, 2013 -- As China rushes to modernize its healthcare system, big cities such as Beijing and Shanghai have attracted most of the attention. But medical imaging vendors are now moving into China's vast countryside. Owen Tang of ChinaBionews offers a look at China's new frontier for growth.
iPad turns in mixed results for chest radiographs
December 19, 2012 -- The iPad appears capable of supporting the diagnosis of pneumothorax on chest radiographs, according to an initial evaluation of an iOS-based image viewing app developed by a team from Massachusetts General Hospital. The group also found that its app, at least for now, didn't fare as well in cases with nonpneumothorax findings.
Chest x-ray use remains stable as high-tech modalities soar
December 12, 2012 -- While utilization of high-tech imaging modalities soared and then slipped over the past decade, use of the humble chest x-ray has continued at a relatively stable rate, researchers found in a study presented at the RSNA 2012 conference.
Time to ditch the chest x-ray, researchers conclude
November 29, 2012 -- CHICAGO - If cost isn't an issue -- and that's a big if -- it's time to say goodbye to chest radiography, say researchers from Norway who compared chest x-ray to ultralow-dose CT. Results were presented on Thursday at the 2012 RSNA meeting.
Low-dose mammo, wireless US probe, 3T MRI pace Siemens at RSNA
November 28, 2012 -- CHICAGO - A new digital mammography system with lower radiation dose, a wireless ultrasound probe, a 3-tesla MRI scanner designed for high-performance clinical and research work, and a new line of angiography systems are among the highlights in the RSNA 2012 booth of Siemens Healthcare.
Radiologists should eye scans for clues to elder abuse
November 28, 2012 -- CHICAGO - The under-the-radar problem of physical abuse of the elderly can be countered by radiologists who observe certain patterns of head and neck injuries, subdural hematomas, and the social context surrounding these cases, researchers reported at RSNA 2012.
CT dose reduction, PET/MRI pace Philips RSNA news
November 28, 2012 -- CHICAGO - New developments in CT dose reduction, an expansion of its digital MRI architecture, and new enhancements in PET/MRI are pacing product news in the RSNA 2012 booth of Philips Healthcare.
Residents need twice the fluoro time to place catheters
November 27, 2012 -- CHICAGO - Radiology residents at two large teaching hospitals in Tennessee required twice as long as interventional radiologists to place central venous catheters under fluoroscopy guidance, effectively doubling the radiation dose to the patient, according to a study presented at the 2012 RSNA meeting.
CT can replace x-ray for pediatric cystic fibrosis patients
November 27, 2012 -- CHICAGO - Ultralow-dose CT is on par with a frontal chest x-ray in terms of dose (0.05 mSv) and gives an accurate diagnosis in pediatric cystic fibrosis patients, Belgian researchers revealed on Monday afternoon at the annual RSNA meeting.
Toshiba's RSNA highlights include new 320-row CT scanner
November 26, 2012 -- CHICAGO - A new flagship 320-detector-row CT scanner, a price drop for its 1.5-telsa MRI scanner, and new technologies in ultrasound and wireless digital x-ray are among the highlights in the RSNA 2012 booth of Toshiba America Medical Systems.
