Targeted breast radiotherapy offers treatment option
November 11, 2013 -- Targeted radiotherapy delivered to women undergoing surgery for early breast cancer could offer a feasible alternative to current procedures, which require daily radiotherapy sessions for weeks after surgery, according to two new studies published in Lancet and Lancet Oncology.
Iterative recon delivers quality CCTA at well under 1 mSv
November 11, 2013 -- Researchers from China and the U.S. have succeeded in producing ultralow-dose coronary CT angiography (CCTA) exams in a wide range of patients using iterative reconstruction. In the process, they've helped redefine low-dose CCTA to mean far less than 1 mSv in all patients, according to study results published in JACC Cardiovascular Imaging.
Early physics training gives radiology residents a leg up
November 8, 2013 -- A new program aimed at infusing a dose of imaging physics into the early training of radiology residents has improved their understanding of both medical physics and radiology, according to an article in the Journal of the American College of Radiology.
Big data and its relevance to medical imaging
November 8, 2013 -- "Big data" is a buzzword you'll be seeing a lot over the next few years as your corporate executive team and healthcare vendors incorporate it into their business development activities. Hjalmer Danielson from Ascendian Healthcare Consulting helps give some definition to the term in this new column.
Speech recognition improves report turnaround time
November 7, 2013 -- Using speech recognition software improved report turnaround time 24-fold in a community radiology practice, according to a new study published online in the Journal of the American College of Radiology.
FFDM finds more high-risk lesions: But is that a good thing?
November 6, 2013 -- Transitioning from analog mammography to full-field digital mammography (FFDM) is associated with a threefold increase in the detection of high-risk lesions. But it can also result in oversurveillance and overtreatment, according to a new study published in the November issue of the American Journal of Roentgenology.
Radiology still looms large in ECRI's top 10 hazards
November 5, 2013 -- Medical radiation no longer tops the top 10 list of technology hazards published each year by the ECRI Institute. That dubious honor, for the second year in a row, goes to those beeping, buzzing, distracting, infuriating, wolf-crying alarms that are becoming ubiquitous throughout healthcare.
New taxonomy could improve rad therapy incident reporting
November 5, 2013 -- Everyone agrees that improvements are needed in reporting incidents during radiation therapy treatments that can affect patients. But such reporting is tricky, especially if radiation oncology facilities aren't even using the same language to describe incidents.
Noninvasive FFR-CT equals cardiac cath for stenosis assessment
November 4, 2013 -- SAN FRANCISCO - A software technique that analyzes CT data performed as well as invasive fractional flow reserve (FFR) for detecting ischemia, offering a potentially better and cheaper way to evaluate patients with suspected coronary artery disease, according to a presentation at the Transcatheter Cardiovascular Therapeutics meeting.
Stress cardiac MR matches 320-row CCTA results
November 1, 2013 -- Vasodilator stress cardiac MR and 320-detector-row coronary CT angiography (CCTA) both accurately detect obstructive coronary artery disease, and the two tests are also highly concordant, according to the results of a new study in the International Journal of Cardiovascular Imaging.
Dubai Hospital reduces CT patient dose through monitoring
October 31, 2013 -- Faced with a doubling of CT volume in their healthcare system over the past five years, researchers from Dubai Hospital used a program of continuous monitoring and action to substantially reduce radiation dose to adult and pediatric patients undergoing common CT exams.
Combination of ultrasound, tPA may boost stroke treatment
October 31, 2013 -- The combination of a novel, operator-independent ultrasound therapy device and tissue-type plasminogen activator (tPA) therapy may be able to increase the rate of artery recanalization in patients with ischemic stroke, according to a study published online October 24 in Stroke.
PET/CT dominates diverse hybrid imaging market
October 30, 2013 -- In Western Europe during 2012, there were 577 providers of PET and/or PET/CT, of which 18 were mobile, and PET/CT accounted for 92% of the installed systems, according to new market research presented last week at the European Association of Nuclear Medicine annual congress, held in Lyon, France.
