3D breast technique shows promise for cancer risk assessment
January 4, 2013 -- Functional 3D infrared imaging displays promise as a breast cancer risk assessment tool, reportedly offering high sensitivity and reasonable specificity, according to a proof-of-concept study published online in European Radiology.
Tailor radiology reports to recipients to save time and money
January 3, 2013 -- Radiology reports that are tailored specifically to the clinical needs of the recipient will save radiologists time and probably will be valued and appreciated more by ordering physicians. This blunt message was delivered by a Belgian expert at RSNA 2012.
CADx outperforms radiologists in characterizing liver lesions
January 2, 2013 -- German researchers have found that a computer-aided diagnosis (CADx) system can do better than radiologists for characterizing indeterminate liver lesions, but they believe CAD systems should work more like radiologists rather than relying too heavily on image analysis.
Low-dose CT raises coronary calcium scores; IR corrects them
January 2, 2013 -- Low-dose coronary artery calcium (CAC) scores are reliable if iterative reconstruction (IR) is applied to the CT data, according to research presented at RSNA 2012. Dutch researchers found that the technology ensures the accuracy of CAC scores that would otherwise be higher and less predictable than the results of higher-dose CT scans.
iPad turns in mixed results for chest radiographs
December 31, 2012 -- The iPad appears capable of supporting the diagnosis of pneumothorax on chest radiographs, according to an initial evaluation of an iOS-based image viewing app developed by a team from Massachusetts General Hospital. The group also found that its app, at least for now, didn't fare as well in cases with nonpneumothorax findings.
New MRI approach can reveal medial meniscus tears
December 28, 2012 -- An upright MRI technique makes it possible to recognize the stability of a meniscal tear and avoid potential damage from arthroscopic investigations, leading to more rapid recovery from injury, according to Italian researchers.
Automated tube current selection keeps CCTA quality, cuts dose
December 27, 2012 -- Using software that automatically selects the tube current modulation significantly reduces the radiation dose in coronary CT angiography (CCTA) compared with manual kV selection based on patient size, researchers from South Korea reported at RSNA 2012.
Top 10 AuntMinnieEurope stories for 2012
December 27, 2012 -- We're pleased to offer the top 10 stories of 2012 on as measured by member traffic. Hot topics in 2012 included the Olympics, the ongoing breast screening debate, regulatory issues surrounding MRI, and the connection between radiology and art.
How the RSNA congress evolved into a global phenomenon
December 24, 2012 -- When RSNA held its first meeting in December 1915, the conference attracted 30 of the nascent society's 62 members to a Chicago hotel. Now closing in on its 100-year anniversary, RSNA still meets in Chicago, but it draws 60,000 radiology professionals to what has become the world's largest medical meeting.
MBIR finds same nodules as ASIR, at fraction of dose
December 21, 2012 -- Second-generation iterative reconstruction software doesn't necessarily improve radiologists' ability to detect lung nodules compared to earlier versions. But the new software permits the same lesion detection power at greatly reduced CT radiation doses, according to a study presented at last month's RSNA 2012 meeting in Chicago.
