ROCHESTER, N.Y., May 27 — The U.S. Food & Drug Administration (FDA) has given marketing clearance to a tabletop laser imager from Carestream Health, Inc., that provides healthcare professionals with output that is ideal for digital mammography and general radiography applications.
The company will begin taking orders immediately for its CARESTREAM DRYVIEW 5850 Laser Imager and will begin shipments in the U.S. and other countries in June.
The new laser imager—featuring 508 pixels-per-inch output—addresses the need for affordable laser-quality film output from full-field digital mammography (FFDM) and CR-based mammography systems. The imager, with two on-line film trays, supports DICOM printing for mammography and general radiography. Mammography printing is available on 20 x 25 cm, 25 x 30 cm and 28 x 35 cm film sizes, while general radiography printing is available on these film sizes as well as 35 x 35 cm, and 35 x 43 cm film sizes. The DRYVIEW 5850 offers a D-max up to 4.0 with proven DRYVIEW laser imager quality and platform reliability.

Varian Medical Systems Introduces the PaxScan 3030+ X-Ray Image Detector for Interventional Angiography
SALT LAKE CITY, May 27 /PRNewswire-FirstCall/ -- Varian Medical Systems, Inc. (NYSE: VAR) X-Ray Products, a world leader in X-ray tubes and supplier of the premier PaxScan® line of digital X-ray image detectors for filmless X-rays, has introduced their first digital imager specifically designed for interventional angiography procedures.
"With speeds up to 30 frames per second, the PaxScan 3030+ allows the physician to monitor interventional procedures, including the placement of catheters within blood vessels, in real-time," said Carl LaCasce, Vice President Imaging Products. "The PaxScan 3030+ provides highly detailed images with excellent contrast and spatial resolution, while delivering a low X-ray dose to the patient."
In addition to interventional angiography systems, the new PaxScan 3030+ multi-modality panel is designed for use in cardiovascular imaging systems and surgical C-arms. The panel's compatible interfaces and software simplify integration into existing systems. It is specially designed for equipment incorporating three dimensional cone-beam CT (CBCT) capabilities.

Side Discrepancy Errors in Radiology Reports Rare But Often Clinically Significant
Side discrepancy errors in radiology reports do occur and it is important that radiologists, referring physicians and patients communicate well to help prevent errors in clinical management, according to a study performed at Massachusetts General Hospital, Boston, MA. “Side discrepancy errors refer to instances when the side of the lesion is incorrectly noted in one or more sections of the radiology report,” said Minal Jagtiani Sangwaiya, MD, lead author of the study.
The study included more than one million radiology reports. “88 side discrepancy errors were reported and 80% of those errors were rated as clinically important. The errors in mislabeling the side of the lesion were almost twice as frequent in female patients as in males. Mammography and radiography, followed by MRI and ultrasound were the most commonly reported techniques with mislabeling of the side of the lesion in identified errors,” said Dr. J. Sangwaiya. The errors noted in the study included those that had been corrected. The study does not account for unrecognized errors.
“While the incidence of side discrepancy errors is very small, most reports describing medical errors are self-reports or surveys and they almost certainly underestimate the incidence, perhaps by a factor of 20 or more,” she said.

Georgia Acknowledges RA as Advanced Practice
On May 11, 2009, Georgia Governor Sonny Perdue signed into law House bill 509, which acknowledges the advanced practice of radiologist assistants.
The bill recognizes the position of radiologist assistants as "an advanced level as determined by board rule." The bill states that the procedures include, but are not limited to, "enteral and parenteral procedures when performed under the direction of the supervising radiologist and may include injecting diagnostic agents to sites other than intravenous, performing diagnostic aspirations and localizations, and assisting radiologists with other invasive procedures."
Christine Lung, ASRT vice president of government relations and public policy said, "By acknowledging radiologist assistants, the passage of this bill is a great first step toward licensing radiologic technologists." Georgia’s enactment of House bill 509 makes it the 25th state to recognize the radiologist assistant. However, it is now the second state not to license R.T.s, while legally recognizing RAs.

Siemens Sets A New Standard In Subtraction Angiography
The new application syngo iFlow from Siemens Healthcare makes it possible for the first time to demonstrate a complete digital subtraction angiography (DSA) sequence in a single color image.
Previously, multiple black and white image frames had to be reviewed to visualize the contrast medium flow through the blood vessels. Now with the colors of syngo iFlow the representation of contrast from its initial entry into the blood vessels to its flow throughout can be shown in one image.
The syngo iFlow application, for example, can be used to enhance pre-procedural and postprocedural imaging of patients under treatment for leg stenosis. Flow deviations and the increased utilization of collaterals can more easily be detected prior to intervention, since anomalies more readily attract the physician's attention due to their specific colors. Following the intervention, the success of a balloon dilatation or stent implantation of a stenosis is readily visible due to the improved flow.
