Imaging finds items not on the menu for BBQ lovers
April 5, 2012 -- Why were people who had recently eaten grilled meat showing up at Rhode Island Hospital in Providence with abdominal pain and painful swallowing? Radiologists and emergency room physicians used x-ray and CT to find the answer -- they had ingested wire bristles from metal brushes used to clean the grills.
SIR: Venous angioplasty relieves multiple sclerosis symptoms
March 28, 2012 -- SAN FRANCISCO - A controversial theory that vascular blockages cause multiple sclerosis (MS) found additional support this week at the Society of Interventional Radiology (SIR) meeting. Researchers showed that using vascular angioplasty to clear blocked veins also quelled some MS symptoms.
SIR: Interventional radiology's role in healthcare is changing
March 27, 2012 -- SAN FRANCISCO - The way healthcare is delivered and reimbursed is changing, and it's crucial for interventional radiologists to understand new models of care in order to protect the subspecialty's turf, according to presentations at the Society of Interventional Radiology (SIR) meeting.
Moments in Radiology History: Part 2 -- Cardiovascular x-ray
March 26, 2012 -- In early 1896, just after the birth of medical x-ray, doctors experimenting with the new rays realized that in addition to imaging bones, the technology was useful for the circulatory system. In part 2 of our series on radiology history, Otha Linton explores the roots of interventional radiology, from Forssmann to Dotter.
Moments in Radiology History: Part 1 -- X-rays after Roentgen
March 21, 2012 -- The story of Roentgen's discovery of x-rays in 1896 is well-known, but less familiar are the advances that came later. In this first article in a new series, radiology historian Otha Linton describes how word of "a new kind of rays" rapidly spread throughout the world, and how the new technology was adopted by medicine.
DR matches analog x-ray for pleural pneumoconiosis
February 16, 2012 -- Another milestone has been reached in establishing equivalency between digital radiography (DR) and conventional film-screen chest radiography for characterizing pneumoconiosis, a set of pulmonary diseases associated with job-related black lung disease and asbestosis.
Study shows CR exposure creep can be slowed, but is hard to stop
January 27, 2012 -- The long-suspected existence of exposure creep has been documented in a long-term study of computed radiography (CR) practices at an Australian teaching hospital. The study highlights the need for uniform exposure standards for CR systems manufactured by different vendors.
Image artifacts degrade digital radiography performance
January 23, 2012 -- New forms of image artifacts can compromise the performance of digital radiography (DR) equipment, say researchers from the Mayo Clinic in Rochester, MN, in the January issue of the American Journal of Roentgenology. The group described its experience with DR artifacts and how to correct for them.
U.S. may allow digital x-ray to monitor black lung in miners
January 12, 2012 -- A new proposal from the U.S. Department of Health and Human Services would allow lung scans of coal miners to be performed with digital x-ray systems in addition to traditional film-based radiography, according to a proposed rule appearing January 9 in the Federal Register.
Report finds 'questionable' Medicare bills for portable x-ray
December 29, 2011 -- A U.S. government investigation has discovered "questionable" billing patterns in portable x-ray services paid for by Medicare, with the federal government paying up to $20 million in unnecessary claims. Government inspectors have recommended stronger controls over Medicare payments for portable x-ray studies.
CR equal to film-screen for monitoring black lung disease
December 22, 2011 -- A new study is helping public health officials gain confidence in chest computed radiography (CR) as an alternative to film-screen x-rays for monitoring black lung disease and other forms of pneumoconiosis.
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.
