Stroke victims not receiving timely imaging
May 2, 2012 -- "Time is brain" in stroke care -- and far too much of both are being lost, according to a neurologist-led study in Stroke that documents the delays most patients are experiencing in many hospitals before the critical step of brain imaging occurs.
CT doses are lower in dedicated pediatric radiology departments
May 2, 2012 -- Radiation exposure from CT was significantly lower when abdominal scans were performed in a dedicated pediatric radiology department compared to scans performed in a department serving both children and adults, researchers report in this month's Journal of the American College of Radiology.
JAMA paper reignites debate over APBI treatment
May 1, 2012 -- The debate over the effectiveness of breast cancer treatment with accelerated partial-breast irradiation (APBI) brachytherapy has resurfaced with the publication of a paper critical of the technology in the May 1 issue of the Journal of the American Medical Association.
ARRS: CT radiation far less risky than underlying disease
May 1, 2012 -- The long-term risk of future cancers associated with CT scans has been under scrutiny for years, but those risks aren't remotely as serious as the risk of dying from the diseases CT is used to diagnose, concluded a study presented on Tuesday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.
ARRS: Rads less savvy than peers on healthcare, business issues
May 1, 2012 -- VANCOUVER - Radiologists admit they're less knowledgeable than their nonradiologist peers on topics such as healthcare policy, quality assurance, and patient costs -- and less savvy in business and management issues, according to a study presented on Monday at the American Roentgen Ray Society (ARRS) annual meeting.
Younger high-risk women may benefit from biennial breast screening
April 30, 2012 -- For women between the ages of 40 and 49 who are at high risk for breast cancer, the benefits of mammography screening every other year outweigh the potential harms, according to a new study published in the May 1 issue of Annals of Internal Medicine.
ARRS: Optimal use is key to managing CT radiation risk
April 30, 2012 -- VANCOUVER - When used optimally, CT is one of medical imaging's most valuable tools. But for patient safety, the challenge is to dial down radiation dose while also increasing image quality, according to a presentation on Sunday at the annual American Roentgen Ray Society (ARRS) meeting.
ARRS: CT useful when abdominal US is inconclusive
April 30, 2012 -- About a third of CT exams performed after inconclusive abdominal ultrasound are positive, making CT a good choice for follow-up in many patients, researchers said on Monday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.
320-row CT cuts pediatric radiation dose versus 64-slice imaging
April 30, 2012 -- Pediatric radiation dose was cut by as much as half for some clinical applications by swapping 64-detector-row CT for 320-detector-row scanning, according to researchers from Cincinnati Children's Hospital Medical Center. The study indicates that advances in CT technology can be successfully used to cut pediatric radiation dose.
