iPad up for challenge of plain radiographs
December 19, 2011 -- An iPad can be used to reliably assess for pneumothorax on plain radiography chest films, potentially opening the door for an increased role for mobile devices in emergency radiography applications, according to research presented at the recent RSNA 2011 meeting in Chicago.
New report shows angio procedure growth stalling
December 15, 2011 -- Procedure volume at U.S. angiography labs slowed to a 1% annual growth rate in 2010, compared with rates greater than 4% in previous years. Future market growth in the angiography segment may rely on sales of replacement systems, according to a new report by market research firm IMV Medical Information Division.
Dose experts look at radiation risk, error, and uncertainty
December 12, 2011 -- What's the latest on risk from medical radiation? It all depends on the exam and the patient, of course, but knowledge is evolving, and some newer evidence suggests higher risks from smaller doses, according to speakers presenting last Friday at a Washington, DC, symposium.
DR chest tomosynthesis helps characterize lung lesions
December 12, 2011 -- The use of chest tomosynthesis with a digital radiography (DR) system enabled radiologists to characterize pulmonary lesions, circumventing the need for further diagnostic workup of patients with CT, according to a study by Italian researchers.
Radiation symposium: Dose tracking calls for collaboration, technology
December 8, 2011 -- Experts from around the world convened in Washington, DC, today for a two-day symposium on finding better ways to track and utilize medical radiation dose. Collaboration is key, speakers said, because the problem of tracking radiation dose is so big that no single country or governmental agency can solve it alone.
DR chest tomo reduces number of CT exams in Sweden
December 6, 2011 -- Using chest tomosynthesis with a digital radiography system reduced the number of chest CT exams performed at a Swedish institution, leading to lower radiation dose and better use of CT resources, according to a presentation from last week's RSNA meeting.
Data-mining tool identifies overexposed chest x-rays
November 30, 2011 -- CHICAGO - Taking a high-quality portable chest x-ray can be difficult, leading to an overexposed image when digital radiography equipment is used. One solution to reduce overexposures is a new data-mining tool, according to a Tuesday presentation at the RSNA 2011 meeting.
Siemens beefs up CT line, launches ultrasound system
November 29, 2011 -- CHICAGO - A pair of new CT scanners is pacing the RSNA 2011 product introductions from Siemens Healthcare. The company is also promoting Biograph PET/CT and its new Acuson S1000 ultrasound system, and is demonstrating new product launches in healthcare informatics, digital radiography, and interventional radiology.
Mammography, CT, PET/MRI pace Philips RSNA product debuts
November 29, 2011 -- CHICAGO - Philips Healthcare is highlighting its renewed push in mammography in its RSNA booth, as well as new product introductions in CT and the ongoing development of its PET/MRI program, which got a boost with a key regulatory clearance before the show.
New angio system leads GE's RSNA product debuts
November 28, 2011 -- CHICAGO - At the top of the agenda in the RSNA 2011 booth of GE Healthcare is a new laser-guided, robotic-controlled interventional angiography system that was unveiled with fanfare at this week's meeting. Also featured are patient-controlled environments for mammography and MRI, a new mobile x-ray system, and a new entry in the vendor's PET/CT product line.
Toshiba RSNA highlights include CT, MRI, ultrasound
November 28, 2011 -- CHICAGO - A new CT scanner, a pair of new ultrasound systems, a wireless digital x-ray unit, and enhancements in coil technology for its MRI line are among the new product launches for Toshiba America Medical Systems at the RSNA 2011 meeting in Chicago.
Cut back on imaging studies after febrile UTI in kids, study suggests
November 14, 2011 -- NEW YORK (Reuters Health) - The benefits of a more selective approach to urinary tract imaging after an initial febrile urinary tract infection (UTI) in children outweigh the risks, according to a group of doctors who have been using a more restrictive policy at their own institution.
JAMA study confirms ineffectiveness of x-ray chest screening
October 28, 2011 -- A large-scale study of more than 150,000 individuals has confirmed that screening with chest radiography does not reduce death rates from lung cancer compared to no screening. The study, published in the October 26 issue of the Journal of the American Medical Association, might be most valuable for the insight it provides into CT lung screening.
Assess fractional flow reserve with easier methods
October 20, 2011 -- NEW YORK (Reuters Health) - Two new approaches make it easier and more efficient to assess fractional flow reserve, a measure of the physiological significance of coronary artery stenosis. The two methods are reported separately in the October issue of JACC: Cardiovascular Interventions.
Dual-energy beats bone suppression in chest imaging
October 11, 2011 -- In a face-off of two digital chest x-ray techniques, dual-energy imaging proved better than a bone-suppression algorithm for detecting small lung cancers on computed radiography images. But the difference was small, and bone suppression may still have some advantages, according to an article published September 22 in Radiology.
Protective drape curbs radiation exposure in complex PCI
September 30, 2011 -- NEW YORK (Reuters Health) - The RadPad (Worldwide Innovations & Technologies) surgical drape reduces scatter radiation during complex percutaneous coronary intervention (PCI) requiring prolonged fluoroscopic screening, a new study finds.
Swissray founder launches new digital x-ray software venture
September 29, 2011 -- The founder of digital x-ray pioneer Swissray International is incubating a new start-up company to commercialize a software algorithm called RAYduce, designed to reduce noise and radiation dose in digital radiography.
Synchrotron scanning offers clues to human brain evolution
September 23, 2011 -- New techniques in synchrotron x-ray imaging have given researchers a surprising glimpse into our collective past: An international group has obtained detailed information about the brain structure of Australopithecus sediba, a new species thought by some to be the true ancestor to modern humans.
Study finds few complications from spinal DSA
September 20, 2011 -- Spinal digital subtraction angiography (DSA) has acquired a reputation as a risky interventional procedure, but that notoriety is largely unfounded, according to a study by researchers from Johns Hopkins University that was published online September 14 in Neurology.
