Computer analysis bolsters liver elastography performance April 14, 2010 -- Computer-enhanced dynamic analysis of ultrasound elastography movies is a useful and reliable method for depicting liver hardness, yielding a high level of interreader agreement, according to research published April 14 in the World Journal of Gastroenterology.
Spanish study finds speech recognition saves time, money April 12, 2010 -- A large study of speech recognition that included nearly 140,000 reports has confirmed the technology's ability to dramatically reduce report turnaround time while saving money. Researchers found that speech recognition slashed turnaround time from about 5.5 hours with conventional transcription to just over one hour.
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.
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.
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.
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.
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.
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.
