CoActiv will introduce its Exam-RIS version 2.0 at RSNA 2011. The web-based RIS integrates with their Exam-PACS, and provides specialized work lists, automated referring physician communications, and an HL7 interface for billing, among other features.

Imaging solutions provider Viztek will be debuting several new features for its Opal-RAD PACS at RSNA 2011, including a cloud-based image viewer.

MRI-compatible audio-visual systems vendor Resonance Technology Company Inc. will introduce new features in its CinemaVision MRI video entertainment system at RSNA 2011.

IT workflow and communications company peerVue will introduce the integration of voice recognition and reporting to its Quality Intelligence and Communication System (QICS) at RSNA 2011.

Do you think stripping out textual identifying information in publicly available radiologic images will protect you against privacy violations? Think again. A paper presented Thursday at the 2010 RSNA meeting showed how facial images reconstructed from maxillofacial sinus and cerebral vasculature images could be matched in a database using commonly available face-matching software.

The dramatic growth of Medicare-related medical imaging utilization-which drew the attention of rate-cutting federal policymakers and the wrath of politicians on Capitol Hill in the mid-2000s-has ended, according to a study from Thomas Jefferson University in Philadelphia.

A study presented Wednesday at the RSNA meeting adds further evidence to the recommendation women with newly diagnosed invasive lobular carcinoma should have their contralateral breast screened with MRI. Most women aren’t routinely screened in the contralateral breast because whether to do so is highly dependent on the surgeon’s preference. This research, however, provides more evidence why they should: MRI detected synchronous breast cancers in 16% of patients.

CT scout or scanogram images make up only about 4% of the typical chest/abdominal scan radiation dose, but are an easy target for dose reductions, according to a study presented Wednesday. Further, as technology changes and protocol updates reduce overall dose rates, scout images will make up a relatively larger part of the total and still represent a good target for cuts.

Cancer patients saw a four to five times greater increase in their average annual exposure to imaging-related ionizing radiation than the general population since 1994, according to a retrospective study of more than one million privately insured people in the U.S.

It should be possible to reduce radiation dose levels by as much as 50% in CT appendicitis scans without seriously sacrificing accuracy, a study presented Tuesday by Duke University researchers concluded.

Study reveals breast pain can be only indicator of breast cancer. Findings challenge reluctance to image for breast pain alone.

U.S. hospitals could save nearly $22 million annually by deemphasizing CT in favor of diagnostic ultrasound as the frontline imaging test for suspected appendicitis. Such a change would also spare many patients unnecessary exposure to ionizing radiation from CT, according to financial evaluation and meta-analysis by Laurence Parker, Ph.D., an imaging economics researcher at Thomas Jefferson University in Philadelphia.

Yearly mammograms greatly reduce the risk of mastectomy following breast cancer in women between the ages of 40 and 50, according to a study presented Wednesday at the RSNA meeting.

A navigation system from Toshiba America Medical Systems has made complex interventions a little simpler.

Remote radiography and fluoroscopy systems traditionally have appealed more to Europeans than to practitioners in the U.S. But Philips is betting the time-and design of its new Juno DRF-are right to make a change in old habits. The Juno DRF remote-controlled flat-detector system, recently cleared by the FDA, offers enhancements that Philips Healthcare is promoting in its RSNA booth as the means to faster workflow and patient throughput and maximized return on investment.

Patients’ risk of developing cancer from CT scans is not as high as previously thought, but the rate still doubled over the time period studied, according to a study presented Wednesday at the RSNA meeting.

Too much visceral fat may increase a woman’s risk of developing osteoporosis, according to a study presented Tuesday at the annual meeting of the RSNA.

Radiologist errors identified from an analysis of 656 imaging exams paints a unique picture describing why radiologists make errors. The analysis also points to ways such mistakes can be prevented.

Bone can obscure lung lesions that may indicate cancer. The latest version of CAD software from Riverain Medical, shown publicly for the first time at RSNA 2010, takes care of the problem.
