Dying cancer patients need shorter palliative radiation therapy
April 12, 2010 -- Radiation oncologists should be less concerned about late-onset radiation dose toxicities when planning palliative radiation therapy protocols for near-death cancer patients, according to a study published online today in Cancer. Read More
Less DNA damage seen after high-pitch coronary CTA
April 9, 2010 -- High-pitch dual-source CT angiography (CTA) scans produce significantly less radiation-related DNA damage than comparable low-pitch dual-source CTA scans -- and, importantly, the DNA results correspond to both measured and derived biological radiation doses, say researchers from Erlangen, Germany.

Exposure index values vary widely between CR systems
April 9, 2010 -- Imaging facilities trying to reduce digital x-ray dose are turning to exposure index (EI) values to see how much radiation patients receive. New research indicates that while this is a good idea for digital radiography, it's not so hot for computed radiography (CR) due to wide variation in EI measures. Read More
Authors of Nordic mammo study no strangers to controversy
April 6, 2010 -- The debate over mammography got hotter last month with the publication of a study by Nordic researchers claiming there's no evidence that mammography screening reduces death rates. Some mammography advocates have taken issue with what they say is an antiscreening bias on the part of the research group. Read More
Open-source software increases colon polyp conspicuity
April 6, 2010 -- Visibility of colon polyps is increased and sensitivity improved with the use of threshold-based color-coding software in virtual colonoscopy, according to a new study from Italy. Even flat lesions were more often visible with use of the open-source 2D-based interpretation software. Read More
Cardiac cath delivers high radiation doses to operators
April 5, 2010 -- The rapid development of new cardiac stents and other medical devices is opening up a world of possibilities for interventional procedures in the cath lab -- but it's also exposing equipment operators to ever-higher radiation doses. Read More
RIS/PACS integration with personal EHR can be a tough task
April 5, 2010 -- Interest is percolating in the use of personal electronic health records (EHRs). But integrating radiology images and information with these records may be a difficult hurdle to clear, if the experience of Heidelberg University Hospital in Germany is any indication. Read More
Simulation can replace sedation for pediatric MRI exams
April 2, 2010 -- Having an MRI exam can be a frightening experience for both adults and children. Getting a pediatric patient to remain motionless during the procedure often requires sedation. But when given the chance to have a realistic, simulated MRI procedure in advance, children as young as 4 may voluntarily cooperate. Read More
Blood infection risk extremely low with VC
March 31, 2010 -- The risk of bloodstream infections such as bacteremia leading to endocarditis is extremely low in virtual colonoscopy -- in fact, infection rates are probably even lower than in conventional colonoscopy, say researchers from Ireland, the U.K., and the U.S. Read More
Shorter EBRT course works well for epithelial disease
March 31, 2010 -- As the sun-worshiping baby boomer generation ages throughout the world, the incidence of epithelial cancer is increasing. For patients with this skin disease, electron beam radiation therapy (EBRT) provides an excellent alternative to surgery, according to a new study published online in Radiotherapy and Oncology.
