Don't redo CT for mild head trauma if patient is stable
An initial CT exam after mild head trauma is a good idea because it can show bleeding in the brain. Repeating the scan, however, is unlikely to yield additional benefits or change management if the patient is stable, according to a new study in the January issue of Neurosurgery.

Resident program managers struggle to balance new demands
As program managers begin to implement far-reaching changes in radiology residency education, most believe they'll need to limit the options available to their residents to choose their own path -- particularly in the fourth year of training -- to ensure a good basic education for core residents, according to a survey presented at RSNA 2012.

NIH study: Cancer screening rates fall over decade
Cancer survivors on the lookout for secondary tumors maintained their traditionally high screening rates, but screening compliance by almost everyone else has declined over the past decade, according to a report published online December 27 in Frontiers in Cancer Epidemiology and Prevention.

Study finds CT radiation risk may be overestimated
The risks from testicular cancer far outweigh the radiation risk from CT exams used to diagnose and monitor it, concludes a study published today in Radiology. While the study was limited to testicular cancer, it illustrates a common mistake being made in estimating the risk of radiation from medical imaging exams.

Low-dose CT raises coronary calcium scores; IR corrects them
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.

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

Professionalism discussions improve residents' understanding
How should medical professionalism be taught to radiology residents? Small group discussions are effective, according to a study presented at the RSNA 2012 annual meeting that focused on teaching the principles of professionalism.

CT screening finds fast-growing lung cancers
Three-fourths of lung cancers detected through CT screening are aggressive, according to the results of a study in the December 4 Annals of Internal Medicine that boosts the value of CT screening while tamping down fears of overdiagnosis.

Time to ditch the chest x-ray, researchers conclude
CHICAGO - If cost isn't an issue -- and that's a big if -- it's time to say goodbye to chest radiography, say researchers from Norway who compared chest x-ray to ultralow-dose CT. Results were presented on Thursday at the 2012 RSNA meeting.
