Embolization procedure aids in weight loss
November 27, 2013 -- Patients who underwent embolization of the left gastric artery for gastrointestinal bleeding experienced a more than 7% decrease in body weight three months after the procedure, according to a study that will be presented at the upcoming RSNA meeting.
Better together: Tomo and energy subtraction enhance chest DR
October 23, 2013 -- Japanese researchers have found that combining two advanced digital radiography (DR) techniques -- tomosynthesis and energy subtraction -- results in major improvements over conventional digital x-ray energy subtraction when imaging pulmonary nodules, according to an article in the November issue of Academic Radiology.
Lancet: Angiography busts theory of venous link to MS
October 8, 2013 -- Countering prior findings that cerebrospinal venous narrowing and multiple sclerosis (MS) go hand in hand, a study incorporating both x-ray venography and ultrasound found that venous narrowing is unrelated to MS. The new results were published online October 9 in Lancet.
Tough love: Pulling infant pads may reduce x-ray dose
September 16, 2013 -- Removing comfort pads from underneath babies in the neonatal intensive care nursery prior to portable radiography exams could potentially reduce the radiation exposure the children receive, according to a study in the October edition of Academic Radiology.
Global x-ray equipment market reaches 7.5B euros
August 22, 2013 -- Driven by continued digitization of x-ray systems and increasing healthcare investments in emerging regions, the global market for x-ray equipment reached 7.5 billion euros ($10 billion) in revenue in 2012 and is expected to increase by 18% to reach 9 billion euros ($12 billion) in 2017, according to market research firm IMS Research.
X-ray attenuating hand cream shields interventionalists
August 15, 2013 -- A new bismuth-oxide-based hand cream recently approved by the U.S. Food and Drug Administration might free interventional radiologists to focus more on their patients and worry less about radiation exposure to their own hands.
Toshiba veteran Ryan takes reins at Samsung's medical division
July 15, 2013 -- Over the past year, South Korean industrial giant Samsung has made clear its ambitions to become a powerhouse in the healthcare market. The company recently took another step toward that goal by naming imaging industry veteran Doug Ryan to lead its Health and Medical Equipment division in North America.
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.
