Radiation concerns broaden beyond CT in ECRI 2013 hazards list
By Eric Barnes
Medical imaging radiation once again made the list of the ECRI Institute's top 10 rankings of technology hazards for 2013. But this year, the nonprofit group expanded the category from just CT to include a broader range of imaging-related radiation hazards.

MBIR takes on ASIR in low-dose chest CT
By Eric Barnes
Thursday, November 29 | 11:10 a.m.-11:20 a.m. | SSQ03-05 | Room S405ABBoth adaptive statistical iterative reconstruction (ASIR) and model-based iterative reconstruction (MBIR) improve image quality at low doses, but does GE Healthcare's more advanced MBIR algorithm produce noticeably sharper lung images?

AIDR 3D boosts image quality at half the dose
By Eric Barnes
Wednesday, November 28 | 3:50 p.m.-4:00 p.m. | SSM20-06 | Room S404ABCompared with filtered back projection reconstruction images, CT images processed with adaptive iterative dose reduction (AIDR) 3D have less noise, better low-contrast resolution, better diagnostic image quality, and less artifact, reported researchers from Leiden University Medical Center.

Study pinpoints optimal ASIR blend for stomach cancer
By Eric Barnes
Wednesday, November 28 | 3:40 p.m.-3:50 p.m. | SSM08-05 | Room E353BWhat's the best blend of adaptive statistical iterative reconstruction (ASIR) for evaluating gastric cancers for postoperative follow-up? Researchers from South Korea wanted to minimize radiation dose but avoid missing a recurrence, so they systematically analyzed the results of different blends.

Cardiac CTA incorporates function, motion analysis
By Eric Barnes
Wednesday, November 28 | 3:40 p.m.-3:50 p.m. | SSM03-05 | Room S502ABA 64-detector-row scanner can deliver anatomic as well as functional information if you follow the lead of Johns Hopkins University researchers, who used the same data for CT angiography (CTA) and cardiac function, motion analysis, and myocardial perfusion information.

320-slice 4D head CTA derived from CTP replaces extra scan
By Eric Barnes
Wednesday, November 28 | 8:55 a.m.-9:05 a.m. | VSNR41-02 | Room E451BA new technique can boost the quality of low-dose head CT perfusion (CTP) to the point where it can replace higher-dose 3D CT angiography (CTA), say Dutch researchers, who will explain their findings in this scientific presentation.

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.

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.

MBIR tops ASIR for ultralow-dose CT enterography
By Eric Barnes
Monday, November 26 | 11:00 a.m.-11:10 a.m. | SSC05-04 | Room E353ARadiation doses from CT enterography can be dramatically reduced with the use of iterative reconstruction. Find out how model-based iterative reconstruction (MBIR) came out on top in this Monday scientific session.
