Automated CAC fares well in CT lung screening scans
CHICAGO - Automated coronary artery calcium (CAC) scoring is robust and accurate when applied to lung cancer screening exams -- even when applied to a different population than the algorithm was designed for, according to results presented on Thursday at the 2015 RSNA meeting.

NCI software automates organ dose measurement
CHICAGO - Radiation dose measurement is about to get a lot easier -- not to mention better and free of charge. Researchers from the National Cancer Institute (NCI) are finalizing a longstanding project to build a user-friendly software program that converts CT dose index volume scanner readouts into accurate organ dose estimates.

Coronary CTA yields prognostic boost over CAC
CHICAGO - In asymptomatic individuals at intermediate risk of coronary artery disease, coronary CT angiography (CCTA) significantly outperformed coronary artery calcium (CAC) scoring for predicting cardiac events over 10 years, according to a Tuesday presentation at RSNA 2015. Is it time to think about replacing CAC with CCTA in people at intermediate risk?

Researchers measure fetal CT dose with SSDE
CHICAGO - A new fetal dose-measurement technique ties CT dose index volume scanner readouts to size-specific dose estimates (SSDEs), opening a door to greater accuracy in fetal dose measurement, according to a presentation at the 2015 RSNA meeting.

Newly detected nodules reveal higher lung cancer risk
CHICAGO - Nodules detected with CT at interim lung cancer screening carry more than twice the risk of nodules present at the first scan, according to new research presented at this week's RSNA 2015 meeting.

Nonsolid lung nodules carry greater cancer risk in women
For lung nodules detected on CT, certain types can pose a higher risk of cancer for women than men, according to a study to be presented at the upcoming RSNA 2015 meeting in Chicago. The results indicate that radiologists may want to consider gender when interpreting CT lung screening scans.
