ROMICAT II shows CCTA cuts hospital time
By Eric Barnes
Wednesday, November 28 | 8:30 a.m.-8:45 a.m. | VSCA41-01 | Room S502ABThe early use of coronary CT angiography (CCTA) in patients with symptoms suggestive of acute coronary syndromes shortens the length of hospital stay and reduces time to diagnosis, according to researchers from Harvard Medical School and Massachusetts General Hospital.

Implementing the ACR's CT dose registry
By Eric Barnes
Tuesday, November 27 | 3:50 p.m.-4:00 p.m. | SSJ21-06 | Room S403AThe University of Washington has implemented the American College of Radiology's (ACR) CT dose registry, documenting a number of challenges relating to software installation, data transmission, and data consistency issues, most of which have been solved, according to researchers.

Multienergy CT improves virtual colonoscopy CAD performance
By Eric Barnes
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.

CTA, arterial DSA most cost-effective modalities for intracranial aneurysm
By Eric Barnes
Tuesday, November 27 | 3:40 p.m.-3:50 p.m. | SSJ18-05 | Room N228CT angiography (CTA) and intra-arterial digital subtraction angiography (IA-DSA) are the most cost-effective modalities for patients presenting to the emergency department with suspected intracranial aneurysm, researchers from the Netherlands have found.

Supine-prone registration for CT colonography taps marginal artery
By Eric Barnes
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.

Low-dose perfusion CT maps vary depending on software
By Eric Barnes
Tuesday, November 27 | 3:00 p.m.-3:10 p.m. | SSJ17-01 | Room N226Cerebral blood volume and cerebral blood flow values for both gray and white matter rise with the use of low-dose CT, according to a study from Radboud University Nijmegen Medical Center in the Netherlands.

Split-bolus spectral CT halves pancreas dose, boosts conspicuity
By Eric Barnes
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
By Eric Barnes
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
By Eric Barnes
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
By Eric Barnes
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
By Eric Barnes
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
By Eric Barnes
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.
