Multienergy CT improves virtual colonoscopy CAD performance

Tuesday, November 27 | 3:50 p.m.-4:00 p.m. | SSJ08-06 | Room E353CMultienergy CT can boost the detection accuracy of computer-aided detection (CAD) in virtual colonoscopy because it provides more information about the chemical composition of materials in the colon than conventional CT, according to researchers from Massachusetts General Hospital.

Supine-prone registration for CT colonography taps marginal artery

Tuesday, November 27 | 3:10 p.m.-3:20 p.m. | SSJ08-02 | Room E353CUse of the marginal artery for registration of supine and prone CT colonography datasets may permit more efficient data registration and improve diagnostic accuracy, say researchers from the U.S. National Institutes of Health.

Split-bolus spectral CT halves pancreas dose, boosts conspicuity

Tuesday, November 27 | 11:50 a.m.-12:00 p.m. | SSG07-09 | Room E353CCT split-bolus spectral CT improves vascular, liver, and pancreatic attenuation and tumor conspicuity in the pancreas compared with two-phase imaging, using half the radiation dose, say researchers from Beth Israel Deaconess Medical Center.

Attenuation-based technique measures patient size for dose estimates

Tuesday, November 27 | 11:40 a.m.-11:50 a.m. | SSG17-08 | Room S404ABSize-specific dose estimates are the big thing in CT dose optimization, of course, but figuring out every patient's size can be a tedious and inexact undertaking. Mayo Clinic researchers will share their time-saving approach in this scientific session.

Perfusion CT evaluates effectiveness of antiangiogenic drugs in NSCLC

Tuesday, November 27 | 11:25 a.m.-11:35 a.m. | VSCH31-14 | Room N230Perfusion CT is more effective than Response Evaluation Criteria in Solid Tumors (RECIST) for evaluating the effectiveness of short-term antiangiogenic chemotherapy for non-small cell lung cancer (NSCLC), according to a group from Calmette Hospital and the University of Lille in France.

Iterative reconstruction won't change diffuse lung disease diagnosis

Tuesday, November 27 | 11:20 a.m.-11:30 a.m. | SSG05-06 | Room S405ABThe use of iterative reconstruction brings important benefits, but it may have little effect on quantifying regional disease patterns in diffuse lung disease -- meaning the techniques can be used interchangeably, according to a study from University of Ulsan College of Medicine in Seoul, South Korea.

Spectral CT can differentiate gastric carcinoma

Tuesday, November 27 | 10:50 a.m.-11:00 a.m. | SSG16-03 | Room S403BSpectral CT can be used to distinguish moderately differentiated adenocarcinoma from poorly differentiated adenocarcinoma and is helpful for evaluating the differentiation state of gastric cancers, say researchers from China.

Contrast-induced nephropathy incidence is overestimated

Tuesday, November 27 | 10:50 a.m.-11:00 a.m. | SSG08-03 | Room S102DCarefully performed studies suggest that the incidence and severity of contrast-induced nephropathy (CIN) after IV contrast injection for CT studies has been overestimated, according to researchers from the Mayo Clinic in Rochester, MN, who examined the incidence and severity of CIN in a meta-analysis.
