What's the minimum CT dose for hepatic metastasis detection?
By Eric Barnes
Tuesday, December 1 | 11:20 a.m.-11:30 a.m. | SSG05-06 | Room E352How low can the CT radiation dose go for hepatic metastasis detection when using advanced iterative reconstruction? Investigators from the Mayo Clinic in Rochester, MN, wanted to see how low advanced iterative reconstruction would take them.

Review course: Today's stroke triage tools
By Eric Barnes
Tuesday, December 1 | 8:30 a.m.-8:55 a.m. | RC305-01 | Room N230How are today's neuroradiologists handling stroke triage? Perfusion CT and perfusion-weighted MRI can assess for ischemic stroke, hemorrhage, vasospasm, brain tumors, seizures, and traumatic brain injury. But not everything is appropriate for every case, according to Dr. Max Wintermark from Stanford University.

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.
