Brian Casey[email protected]Digital X-RaySiemens to launch new Artis Q angio line at RSNASiemens Healthcare is planning to launch a new line of premium angiography systems, called Artis Q, at the upcoming RSNA meeting in Chicago. The new line includes enhancements in detector design, guidance technology, and x-ray tube instrumentation.November 18, 2012ISTechnique estimates pediatric dose for DR studiesMonday, November 26 | 12:15 p.m.-12:45 p.m. | LL-PDS-MO2A | Lakeside Learning CenterHeightened concern over radiation dose has led to the development of new methods for calculating and reporting dose delivered to patients during imaging exams. Most of the attention has focused on CT -- but what about digital radiography (DR)?November 15, 2012UltrasoundAnalyzing the 2012 election; Road to RSNA rolls on; putting ultrasound firstNovember 14, 2012BreastStereo mammography; major step for ABUS; hope for VC payments?November 12, 2012RSNARoad to RSNA 2012: Digital X-Ray PreviewThis year's presentations on digital x-ray at RSNA 2012 illustrate the rapid advances being made in this modality. Radiography's conversion to digital is making possible the use of advanced image-processing tools once reserved for more advanced modalities, raising the possibility of better patient care at lower radiation doses.November 12, 2012Digital X-RayDigital tomosynthesis a good option for orthopedic examsLL-MKE4552 | Lakeside Learning CenterIn this poster presentation, Japanese researchers will describe the basic principles of digital tomosynthesis radiography for orthopedic applications.November 12, 2012Digital X-RayPoster offers overview of dual-energy subtraction DRLL-CHE2366 | Lakeside Learning CenterIn this poster, a team from the University of Washington will provide an overview of dual-energy subtraction, a relatively new digital radiography (DR) technique.November 12, 2012Digital X-RayDual-energy x-ray detects cardiac calcificationsLL-CHE2351 | Lakeside Learning CenterIn this poster presentation, researchers from University Hospitals in Cleveland will discuss their use of dual-energy subtraction to detect signs of cardiovascular disease that might not show up on standard chest x-rays.November 12, 2012RSNAChest x-ray use remains stable despite growth in advanced imagingThursday, November 29 | 12:15 p.m.-12:45 p.m. | LL-HPS-TH2A | Lakeside Learning CenterUse of basic chest radiography has remained relatively unchanged over the past decade, despite wide fluctuations in procedure volume for more advanced imaging modalities such as CT and MRI, according to a group from Thomas Jefferson University.November 12, 2012CTUltralow-dose CT matches chest radiography radiation doseThursday, November 29 | 11:20 a.m.-11:30 a.m. | SSQ03-06 | Room S405ABRecent advances in iterative reconstruction have put CT radiation doses within range of those found in chest radiography. So is ultralow-dose CT a realistic alternative to x-ray for chest studies? Researchers from Rikshospitalet at the University of Oslo wanted to find out.November 12, 2012Previous PagePage 2 of 190Next PageTop StoriesImaging InformaticsSIIM: Nina Kottler speaks on improving efficiency with AINina Kottler, MD, speaks with AuntMinnie about how radiologists are using AI to improve workflow efficiency.AISIIM: Brad Erickson talks research challenges, retirementAISIIM: Operational consideration needed for AI in radiation oncologyUltrasoundUltrasound MinnieCast, Episode 10: How to apply POCUS oversight in your hospitalSponsor ContentWebinar: AI for CT & PET/CT Imaging
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
