FFR-CT after cardiac CT found accurate across demographic spectrum
By Eric Barnes
Thursday, December 5 | 11:30 a.m.-11:40 a.m. | SSQ03-07 | Room S504ABThis scientific session will discuss a study in which fractional flow reserve CT (FFR-CT) yielded similar discrimination and accuracy to invasive FFR for diagnosing lesion-specific ischemia across a variety of patients.

Advanced iterative reconstruction enhances cranial CT
By Eric Barnes
Thursday, December 5 | 11:00 a.m.-11:10 a.m. | SSQ14-04 | Room N228Using a commercially available iterative reconstruction protocol both reduces noise and improves image quality in cranial CT images, according to researchers from University Medical Center Mannheim in Germany.

Tumor shrinkage post-treatment confers excellent prognosis in kidneys
By Eric Barnes
Thursday, December 5 | 10:40 a.m.-10:50 a.m. | SSQ10-02 | Room E450BShrinkage of 10% or more on CT post-treatment is highly predictive of good outcomes in renal cell carcinoma, according to a new study from Boston.

Controversy session probes CT radiation and risk
By Eric Barnes
Wednesday, December 4 | 4:30 p.m.-6:00 p.m. | SPSC42 | Room N228This session will take a new look at the data used to evaluate the association between radiation exposure and cancer risk. The participants will examine how those data have been used to quantify risk and assess the uncertainties inherent in those estimates.

Session probes 'dollars and sense' of lung cancer screening
By Eric Barnes
Wednesday, December 4 | 4:30 p.m.-6:00 p.m. | SPSC41 | Room E450AThe debate over CT lung cancer screening isn't just about safety, it's about dollars. This special controversy session takes on the issue with National Lung Screening Trial data, addressing what the information shows, along with the limitations and cost-effectiveness of screening.

Iterative reconstruction plus new detector circuitry aids stent assessment
By Eric Barnes
Wednesday, December 4 | 3:50 p.m.-4:00 p.m. | SSM20-06 | Room S404ABCT with iterative reconstruction is racking up points throughout the body for high-resolution imaging at low doses, but improved detector technology also is an important part of the picture in boosting the quality of low-dose imaging, according to German researchers.

Iterative reconstruction permits sub-mSv CT colonography
By Eric Barnes
Wednesday, December 4 | 11:20 a.m.-11:30 a.m. | SSK05-06 | Room E351Researchers dialed their CT radiation dose way down -- to 1 mSv per CT colonography exam -- and reconstructed the images using two different iterative reconstruction algorithms in this study from Korea.

Costs remain low in workup of extracolonic findings
By Eric Barnes
Wednesday, December 4 | 10:30 a.m.-10:40 a.m. | SSK05-01 | Room E351In this scientific session, Italian investigators will discuss their conclusion that it's not expensive to work up patients with potentially serious extracolonic findings, especially considering the benefits of finding serious conditions early.

High-resolution breast CT outperforms FFDM and tomo
By Kate Madden Yee
Tuesday, December 3 | 3:30 p.m.-3:40 p.m. | SSJ02-04 | Room E450AHigh-resolution breast CT produces 3D images that are better than full-field digital mammography (FFDM) and tomosynthesis, and it does so at acceptable dose levels for screening procedures, according to German researchers.

Contrast breast CT shows promise for visualizing malignant masses
By Kate Madden Yee
Tuesday, December 3 | 3:10 p.m.-3:20 p.m. | SSJ02-02 | Room E450AIs contrast-enhanced dedicated breast CT better than tomosynthesis and digital mammography for visualizing suspicious lesions? Researchers from the University of California, Davis Medical Center will address this question during this Tuesday scientific session.

Breast DECT shows potential to predict malignancy
By Eric Barnes
Tuesday, December 3 | 10:40 a.m.-10:50 a.m. | SSG14-02 | Room S403BOne of the hardest jobs in diagnostic radiology is distinguishing benign from malignant findings. So a new project that harnesses dual-energy CT (DECT) to analyze water, lipid, and protein content of breast tissue and identify malignancies with high accuracy is welcome news.
