Ultrasound Elastography Developments Lead to Increased Sensitivity of Malignant Nodes
March 4th 2011Ultrasound elastography is shown to raise sensitivity by 24 percent for preoperative assessment of axillary metastases in suspected breast cancer. Meanwhile, microbubbles identify sentinel lymph nodes, minimizing operations, according to researchers presenting at ECR 2011.
ECR 2011 Preview: Q&A with Prof. Yves Menu
February 28th 2011In anticipation of the European Congress of Radiology 2011, which will be held March 3 to 7 in Vienna, Austria, Diagnostic Imaging caught up with Professor Yves Menu, chairman of the department of radiology at Saint Antoine Hospital in Paris and the ECR 2011 Congress President.
Podcast: Preparing for Accountable Care Organizations
January 28th 2011The new ACO model could dramatically affect how radiologists practice, and now’s the time to get involved in the process. Dr. Steven Gerst, MD, MBA, MPH, CHE, vice president of medical affairs at technology company MedCurrent, sheds some light on ACOs and what radiologists should be doing now to prepare.
AHRA 2011: Get 'Er Done: Management Best Practices from the Pros
January 19th 2011GRAPEVINE, TX -No one's plates are getting any less full these days. So when thrown a new work project, it's best to breathe and strategize, practice management consultants told attendees of the annual AHRA conference this week.
CT Coronary Angiography Radiation Can Be Reduced While Maintaining Image Quality
January 7th 2011Through carefully calculated adjustments to coronary imaging using dose-reduction techniques, cardiologists have managed to reduce the radiation delivered to patients undergoing coronary angiograms considerably. Plus, it’s possible to maintain good image quality throughout, researchers found.
Reconstructions of radiologic facial images could strip away patient privacy
December 3rd 2010Do 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.
Diagnostic imaging utilization slows
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.
Patients with invasive lobular carcinoma should get MRI screening, study finds
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.
For cutting CT dose, start with the scout scan
December 2nd 2010CT 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.
Growth in cancer patients’ radiation exposure exceeds that of general population
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.
Shift to ultrasound for appendicitis could reap $21.8 million annual savings
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.
Philips RF remote product offers workflow advantages
December 1st 2010Remote 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.
Cancer risk from CTs not as high as previously thought, study finds
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.
