Toshiba's RSNA highlights include new 320-row CT scanner
November 26, 2012 -- CHICAGO - A new flagship 320-detector-row CT scanner, a price drop for its 1.5-telsa MRI scanner, and new technologies in ultrasound and wireless digital x-ray are among the highlights in the RSNA 2012 booth of Toshiba America Medical Systems.  Discuss
Virtual colonoscopy shows muscle in finding lesions
November 25, 2012 -- CHICAGO - In a series of presentations at the RSNA 2012 annual meeting, researchers from Korea, Italy, and the U.S. described advances in detecting and diagnosing cancer through the use of virtual colonoscopy, also known as CT colonography or CTC.  Discuss
PET/MRI tops DWI-MRI for head/neck lymph node metastases
November 25, 2012 -- CHICAGO - PET/MRI outperformed diffusion-weighted MRI (DWI-MRI) for detecting lymph node metastases in the staging of head and neck cancer patients, according to a study presented on Sunday at the RSNA annual meeting.  Discuss
Breast US could be option for primary cancer screening
November 25, 2012 -- CHICAGO - Breast cancer incidence is increasing worldwide, but screening mammography isn't always available. Could ultrasound serve as a primary test for breast cancer in countries without access to mammography? It's possible, according to research presented on Sunday at the RSNA meeting.  Discuss
RSNA's Image Share project tackles patient concerns
November 25, 2012 -- CHICAGO - RSNA's Image Share pilot program for patient-driven image exchange has encountered a small number of problems with participants, but most are technical or IT-related and can be readily solved, according to research presented on Sunday at the 2012 RSNA meeting.  Discuss
Hitachi extends oval-bore MRI to 3 tesla with Trillium Oval
November 25, 2012 -- At the 2011 RSNA meeting, Hitachi Medical Systems America raised eyebrows with the launch of Echelon Oval, a 1.5-tesla MRI scanner with an oval-shaped magnet. This year, Hitachi extends the oval concept to 3 tesla with Trillium Oval, a work-in-progress scanner not yet for sale in the U.S.  Discuss
Make yourself more visible, RSNA president insists
November 25, 2012 -- CHICAGO - "Step out from behind the curtain and put a face on the radiologist" was the resounding message of Sunday morning's opening session at the annual RSNA meeting. Dr. George Bisset III, RSNA president, emphasized the meeting's theme during his opening remarks and was echoed by colleagues in sessions that followed.  Discuss
Australians tackle challenge of designing low-cost RT system
November 25, 2012 -- CHICAGO - An Australian research team has designed a compact radiotherapy (RT) system intended to lower the costs of building and operating a radiotherapy center. The goal is to reduce a known global shortage of radiotherapy, especially in countries with challenged economies.  Discuss
November 16, 2012 -- Once again, this is a year focused on healthcare IT and imaging informatics at the 2012 RSNA conference. It would be an understatement to say that there are a staggering number of courses, scientific sessions, educational exhibits, and poster presentations -- even the subject of the Eugene P. Pendergrass New Horizons Lectures has an informatics slant.
November 15, 2012 -- At this year's RSNA conference, look for MRI to garner increasing attention as a viable modality in clinical applications where radiation exposure is a concern. In addition, radiologists are using MRI to discover previously hidden secrets in the brain for afflictions such as Alzheimer's disease, cognitive disorders, multiple sclerosis, and stroke.
November 14, 2012 -- Hot topics in women's imaging at this year's RSNA meeting include breast ultrasound and digital breast tomosynthesis (DBT), and attendees can expect to encounter everything from refresher courses to scientific sessions devoted to these technologies. But don't be surprised to hear a lot about breast MRI as well.
November 13, 2012 -- This 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, 2012 -- The growing power of advanced visualization technology will be ever-present in the scientific program at this month's RSNA meeting in Chicago. Hot topics this year include computer-aided detection (CAD) and computer-aided diagnosis (CADx) technology, as well as quantitative imaging. Look for a range of papers on CAD and, in particular, CADx, as researchers increasingly explore the use of computer-aided technology to assist in diagnosis, not just detection.
November 8, 2012 -- For molecular imaging, PET/MRI undoubtedly will garner considerable attention at the 2012 RSNA meeting in Chicago, as the hybrid modality gains interest with each new study that exalts its clinical potential. Preview the noteworthy molecular imaging and nuclear medicine scientific papers that will cover a wide range of clinical applications which will evaluate and benefit patient outcomes.
November 7, 2012 -- Could ultrasound be the primary screening test for breast cancer? Is the public served by the increasing use of handheld ultrasound? These questions and many more will be addressed at the upcoming RSNA meeting in Chicago
November 6, 2012 -- RSNA 2012 caps an extraordinary year for CT fans who like their technology high and their radiation doses low. The CT-focused scientific sessions at this year's show explore a broad array of CT topics that are driven, more than anything, by the need to get more image information with less radiation.
November 5, 2012 -- A variety of PACS educational opportunities await RSNA attendees this year, including research on mobile devices, image sharing, teleradiology, compression, quality assurance, disaster recovery, cloud computing, and more.
