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.

Imagers know that you can skip the contrast in heavier patients undergoing CT scans for suspected appendicitis, but just how heavy is heavy enough?

A new study reports that the use of CT in the nation’s emergency departments is growing exponentially. If the growth trend continues, by 2011, nearly 20% of all emergency department visits may involve a CT exam. The results of this study were presented Monday at the annual meeting of the RSNA.

A new approach that detects breast cancer vasculature is making an appearance at the 2010 RSNA meeting. The method, called high spectral and spatial resolution, or HiSS, uses water to detect tumor blood vessels without contrast.

A Monday morning scientific session covering cardiac CT dose and noise broke down into newsworthy matched pairs: two studies examining the implication of CT radiation on public health, two investigating the impact of radiation reduction strategies on patient dose and image quality, and a third pair considering how noise reduction from iterative reconstruction affects the quality of images of highly calcified vessels and morbidly obese patients.

Philips is adding to its portfolio a new line of CT scanners and a new line of PET/CTs based on dose-saving technologies. Ingenuity CT will displace Philips’ Brilliance line of CTs in configurations up to 128 slices; the Ingenuity TF PET/CT will displace the company’s Gemini platform of PET/CTs. Philips will not stop making these older models, but will feature them in its product portfolio as alternatives to the latest releases.

Hologic has pursued breast tomosynthesis as a commercial modality for the last five years, recruiting luminaries with track records in tomo going back a decade or more. Now, at RSNA 2010, the company is on the brink of achieving that objective.

A radiation monitoring system that quantifies the radiation being absorbed in the fluoro suite promises to give individual staff the information they need to minimize their exposure to x-rays. Philips Healthcare came up with the product, called DoseAware, which the company unveiled earlier this year at the European Congress of Radiology and now on the RSNA 2010 exhibit floor.

Philips’ new xMatrix brings real-time volumetric scanning to radiology as part of the company’s latest version of the iU22 ultrasound scanner. First built into Philips’ echocardiography systems five years ago, a souped-up version built into the company’s flagship iU22 on the RSNA exhibit floor quickly captures volumes in the abdomen that can be interrogated in 2D planes any time after the patient has left the exam room. Two planes can be viewed simultaneously using Live xPlane. Images drawn from the volume can then be sent to any PACS.

Using 80-kVp CT pulmonary angiography for patients suspected of CT pulmonary embolism reduces radiation exposure, significantly increases contrast medium attenuation in the pulmonary arteries, and doesn’t look much different from standard dose, according to a study presented Tuesday at the RSNA meeting.

A few modifications to the radiology order form can serve an important function in encouraging physicians to adopt evidence-based practices when ordering CT to evaluate small pulmonary nodules, according to a study from Dartmouth-Hitchcock Medical Center.

People with obstructive sleep apnea have a higher risk of developing coronary atherosclerosis and coronary artery disease, according to a study presented Tuesday at the annual RSNA meeting.

Mobile devices for image display scored well in scientific papers presented Monday but still face significant hurdles before they are ready to become a routine part of image interpretation.

Athletes are known for playing through injuries, and a new study presented Monday at the RSNA annual meeting says that sometimes it’s safe for them to push through pain.
