Photon-counting CT: Dose comparison with conventional CT

Sunday, November 29 | 10:55 a.m.-11:05 a.m. | SSA19-02 | Room S403B

In this talk, researchers will discuss their efforts to compare dose efficiency between an investigational photon-counting CT scanner and conventional CT.

Tube current modulation vs. size-specific dose estimates

Monday, November 30 | 10:50 a.m.-11:00 a.m. | SSC10-03 | Room S504CD

Size-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.

Multiphase CT enterography finds obscure GI bleeds

Monday, November 30 | 3:00 p.m.-3:10 p.m. | SSE08-01 | Room E353C

Multiphase CT enterography is an effective option for detecting the source of gastrointestinal (GI) bleeds, according to this study to be presented on Monday afternoon.

Photon-counting CT algorithm cuts noise in multienergy CT

Monday, November 30 | 3:00 p.m.-3:10 p.m. | SSE22-01 | Room S403B

In this scientific session, researchers from the Mayo Clinic in Rochester, MN, will discuss their use of a new algorithm to reduce noise in multienergy CT scans.

What's the minimum CT dose for hepatic metastasis detection?

Tuesday, December 1 | 11:20 a.m.-11:30 a.m. | SSG05-06 | Room E352

How 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.

Tin filters and lung nodule CT at x-ray exposure levels: Accurate?

Thursday, December 3 | 11:10 a.m.-11:20 a.m. | SSQ19-05 | Room S403B

How well does CT equipped with a tin filter measure lung nodule volumes at radiation dose levels similar to those of a chest x-ray? Pretty well, most of the time, Mayo Clinic researchers will report in this Thursday presentation.
