Controversy session probes CT radiation and risk
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.

Costs remain low in workup of extracolonic findings
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.

Breast DECT shows potential to predict malignancy
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.

Micro-PET/CT images of rats. (a) At 24 hours in the control group, F-18 FDG uptake in rats brain tissue was normal, and the PET/CT images were red and white; (b) At 7 days in the control group, F-18 FDG uptake in rats brain tissue were normal, and the PET/CT images were red and white; (c) At 24 hours after TMT exposure, F-18 FDG uptake in rats brain tissue were in a low state, and the PET/CT images were orange and yellow. (d) 7 days after TMT exposure, F-18 FDG uptake in rats brain tissue further decreased, and the PET/CT images appeared yellow and light yellow. There was no significant difference in the uptake of muscle tissue between the model group and the control group, and the PET/CT image was blue.
