iPad turns in mixed results for chest radiographs
By Erik L. Ridley
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.

MBIR finds same nodules as ASIR, at fraction of dose
By Eric Barnes
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.
