Sports-related head injuries spur avalanche of CT scans July 30, 2015 -- Emergency department admissions for sports-related head injuries have skyrocketed in recent years -- and so have unnecessary CT scans to evaluate them, according to a new report in the American Journal of Emergency Medicine.
Study maps CT radiation doses in 200K exams July 27, 2015 -- Have you ever wondered how your facility's CT radiation dose levels stack up against those of other institutions? A study in Radiology describes the experience of researchers from five University of California campuses who measured dose in nearly 86,000 adults and children undergoing common CT scans.
4D parathyroid CT sorts out lesion types July 24, 2015 -- CT scans with 4D image reconstruction can separate parathyroid adenomas and hyperplastic lesions into three distinct lesion types based on enhancement patterns, alerting surgeons to the variations they will find, according to a study in Radiology. The findings also indicate that a three-phase scanning protocol is still needed, the authors believe.
Cardiac CTA study links medical radiation to DNA damage July 23, 2015 -- A study published July 22 in JACC: Cardiovascular Imaging is delivering good news and bad news about medical radiation. The bad news: Researchers found measurable evidence of damage to DNA after cardiac CT angiography (CCTA) scans. The good news: There was no sign of damage at radiation levels lower than 7.5 mSv.
AHRA: Reducing radiation is simple but not easy July 23, 2015 -- Managing radiation dose is a hot topic in healthcare among both clinicians and patients. So how can your facility address concerns about excess dose while also improving patient care? The solution is simple -- but not necessarily easy, according to a presentation this week at AHRA 2015 in Las Vegas.
CT provides fresh revelations about ancient Egypt July 22, 2015 -- CT has reached a level of such sophistication that we can now pinpoint incredible detail inside mummies, turning CT into 3D volumes and then segmenting the data, a leading expert told attendees at last week's "The Curious World of Radiology" seminar.
How to avoid Medicare CT scan payment denials July 22, 2015 -- Are your Medicare claims for CT services at risk of being rejected because they resemble "improper" scans? In this article, Jeff Majchrzak of Panacea Healthcare Solutions describes how to avoid submitting billing reports that raise red flags at the U.S. Centers for Medicare and Medicaid Services.
MGH saves money and time printing 3D hearts July 17, 2015 -- Researchers at Massachusetts General Hospital (MGH) in Boston say that having a 3D rapid prototyping printer in the cardiac imaging department is a potential boon for procedure planning and patient education -- and it doesn't break the bank.
AAPM: Fetal CT dose calculator offers easy, accurate estimates July 15, 2015 -- A new technique that calculates fetal dose from CT scans given to pregnant women is accurate and easy to perform, according to a study presented at this week's American Association of Physicists in Medicine (AAPM) 2015 annual meeting in Anaheim, CA.
JACR: Radiologists order CT, MR exams appropriately July 13, 2015 -- When it comes to abdominal CT and MRI, radiologists are making good use of all available prior imaging before recommending additional exams, and they aren't ordering many unnecessary exams, according to a new study published in the Journal of the American College of Radiology.
