RSNA 2012 News
CT can replace x-ray for pediatric cystic fibrosis patients
November 27, 2012 -- CHICAGO - Ultralow-dose CT is on par with a frontal chest x-ray in terms of dose (0.05 mSv) and gives an accurate diagnosis in pediatric cystic fibrosis patients, Belgian researchers revealed on Monday afternoon at the annual RSNA meeting.  Discuss
PET/MRI matches PET/CT for gynecological malignancies
November 27, 2012 -- CHICAGO - PET/MRI can be comparable to PET/CT and holds "great promise" for patients with gynecological malignancies, potentially reducing scan time and radiation exposure, according to a study presented on Monday at the RSNA annual meeting.  Discuss
Tomosynthesis plus FFDM slashes recall rates
November 27, 2012 -- CHICAGO - Adding digital tomosynthesis to mammography for screening lowers recall rates by at least a third -- particularly in younger women or those with dense breast tissue, according to a scientific session given Monday afternoon at the RSNA meeting.  Discuss
GE unites PACS and 3D, quiets MRI scans, shows ABUS at RSNA
November 27, 2012 -- CHICAGO - A variety of new technology is on display in the RSNA booth of GE Healthcare, ranging from an automated breast ultrasound (ABUS) scanner to MRI noise reduction techniques. The vendor will also highlight new image viewing software that unifies its PACS and advanced visualization applications into a single viewing platform.  Discuss
MRI shows bicycling may help patients with Parkinson's
November 27, 2012 -- CHICAGO - In a study using functional connectivity MRI, researchers found that patients with Parkinson's disease who more quickly pedaled a stationary bicycle showed positive brain changes associated with improved motor function. The results were presented on Monday at RSNA 2012.  Discuss
DTI-MRI indicates chances of concussion recovery
November 26, 2012 -- CHICAGO - Use of diffusion-tensor MRI (DTI-MRI) could help detect subtle injuries that can last from hours to months in patients with mild traumatic brain injury, according to a study presented on Monday at the RSNA annual meeting.  Discuss
Meaningful use is achievable for academic radiology practices
November 26, 2012 -- CHICAGO - Should a U.S. academic radiology practice participate in the "meaningful use" initiative? An academic hospital with a program in place could provide significant benefits, but without it, there will be hurdles, according to a Sunday afternoon refresher course at the RSNA annual meeting.  Discuss
CT emphysema measures higher in former vs. current smokers
November 26, 2012 -- CHICAGO - Confirming a counterintuitive finding that researchers will need to explore more fully, current long-term smokers showed lower CT measures of emphysema than former smokers in a study presented on Monday at the RSNA meeting.  Discuss
Professional societies should steer medical error discussion
November 26, 2012 -- CHICAGO - Guidance from professional societies such as RSNA would go a long way in helping radiologists address medical errors, not only in facilitating the process, but also in helping to define errors in the first place, according to a Monday morning session at the RSNA annual meeting.  Discuss
Advanced imaging spending drops to bottom of services list
November 26, 2012 -- CHICAGO - A decrease in volume growth and cuts to Medicare payments have left advanced medical imaging near the bottom of all healthcare service categories contributing to overall Medicare spending -- rather than at the head of the pack as policymakers continue to believe, according to research presented Monday morning at RSNA 2012.  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.
