Tube current modulation vs. size-specific dose estimates
By Eric Barnes
Monday, November 30 | 10:50 a.m.-11:00 a.m. | SSC10-03 | Room S504CDSize-specific dose estimates (SSDEs) are credited with bringing new levels of accuracy to radiation dose estimates by allowing dose to be tailored to patient size in a straightforward way. But how well SSDE works with automated tube current modulation, another mainstay of CT imaging, is still up for debate.

DECT measures treatment response in pancreatic cancer
By Eric Barnes
Sunday, November 29 | 11:45 a.m.-11:55 a.m. | SSA06-07 | Room E353ATumor volume often falls significantly after chemotherapy, but the drop in iodine uptake may be more significant for prognosis. A group from Johns Hopkins University measured treatment response using iodine uptake with dual-energy CT (DECT) before and after treatment of pancreatic cancer.

Road to RSNA 2015: CT Preview
By Eric Barnes
As RSNA 2015 turns a sprightly 101 this year, CT continues to pull tricks out of what always seems like its bottomless hat. In 2015, the all-purpose modality is doing its old tricks better than ever, and it's pulling off some new ones that hadn't seen much play before. Highlights this year include x-ray phase-contrast CT, an investigational photon-counting CT scanner, lung cancer screening, and new and improved iterative reconstruction techniques.
