DR tomo holds promise for fungal pneumonia surveillance
April 11, 2014 -- Tomosynthesis with digital radiography (DR) could be a useful tool for following patients with neutropenia for signs of fungal pneumonia. Researchers from the University of Washington said the technique could offer better performance than conventional x-ray without the radiation dose of CT.
Chest x-ray still has value for tuberculosis screening
April 9, 2014 -- Should low-dose CT replace chest radiography for determining whether patients scheduled for immunosuppressive therapy have latent tuberculosis? Not yet, according to German researchers, who believe chest radiography still has a role to play.
SIR study eyes whether radiation causes cataracts
March 31, 2014 -- Are interventional radiologists more prone to cataracts due to medical radiation? The question was investigated at last week's Society of Interventional Radiology (SIR) conference by an eye specialist who spent the meeting peering into the eyes of attendees, looking for early signs of eye disease.
Case report: Interventional retrieval of portacath fragment
March 10, 2014 -- Portacaths are commonly indicated for long-term administration of parenteral medications. This case report details the successful interventional retrieval of a fractured portacath fragment with cardiac migration. This is rather an unusual complication that, at times, can be life-threatening.
Multimodality vendors launch scanners at ECR 2014
March 9, 2014 -- VIENNA - In the past, ECR languished in the shadow of Chicago's RSNA show when it came to new product introductions. But ECR is slowly coming into its own, as indicated by new product launches from the major multimodality companies at this week's congress.
Pint-sized DR unit takes portability to new level
February 28, 2014 -- South Korean researchers have taken the concept of mobile digital radiography (DR) to a new level, developing a prototype of a portable DR system that's just over 2 ft tall. What's more, the pint-sized unit is able to send images wirelessly to smartphones, according to an article in the Journal of Digital Imaging.
Tomosynthesis nearly equals MRI for rheumatoid arthritis
February 11, 2014 -- Digital tomosynthesis is nearly as good as MRI for detecting signs of rheumatoid arthritis, and both are much better than the reference standard, conventional radiography, according to a new study in the February issue of the American Journal of Roentgenology.
Medical imaging plays role in diagnosis and follow-up of MERS
February 3, 2014 -- Patients with Middle East respiratory syndrome (MERS) have a unique presentation that clinicians are learning to recognize -- and medical imaging plays a role in both diagnosing and following up cases, according to researchers from Saudi Arabia in a new paper in Annals of Internal Medicine.
Siemens RSNA launches include Force CT scanner, angio unit
December 4, 2013 -- CHICAGO - Siemens Healthcare is launching a range of new products at this week's RSNA meeting, including the third generation of its dual-source CT architecture, a new angiography system, and a major ultrasound technology upgrade.
New Revolution CT scanner paces GE's RSNA introductions
December 3, 2013 -- CHICAGO - A new CT scanner called Revolution that acquires 16 cm of data per rotation is the RSNA 2013 highlight for GE Healthcare. The vendor is also showcasing women's imaging, a rebranding of its automated breast ultrasound technology, and a new angiography system with large-format digital detectors.
Philips paces RSNA launches with PET/CT, CT, US scanners
December 2, 2013 -- CHICAGO - New technologies being launched by Philips Healthcare at this week's RSNA meeting include a PET/CT scanner with new digital detectors, a CT system optimized for spectral imaging, and an ultrasound platform designed for both cardiology and radiology applications.
Toshiba RSNA highlights include CT, MRI upgrades
December 2, 2013 -- CHICAGO - Toshiba America Medical Systems is offering RSNA 2013 attendees a look at a wide variety of technologies, including an automated CT scanning mode, dose management for interventional imaging, and productivity enhancements in MRI and ultrasound.
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.
