CAD nabs the flat polyps VC readers may miss
March 9, 2008 -- VIENNA - In two studies presented Sunday at the 2008 European Congress of Radiology, investigators tested colon computer-aided detection (CAD) schemes for their ability to find flat lesions. In both, the sensitivity was reassuringly high, though questions remain about the effect of false-positive CAD detections on reader performance and variations in flat polyp morphology.
Mobile DR helps cut ED image transmission times
March 9, 2008 -- VIENNA - Using a mobile digital radiography (DR) system in the emergency department (ED) ward helped a radiology department at a French hospital cut the amount of time to image ED patients in half, according to a presentation on Sunday at the 2008 European Congress of Radiology. But the department's efforts to make the efficiency gains permanent have been stymied by government regulations on radiation exposure in healthcare facilities.
Dose studies delve into coronary CTA
March 8, 2008 -- VIENNA - At the 2008 European Congress of Radiology (ECR) on Saturday, researchers presented a pair of studies that examined the radiation dose of coronary CT angiography (CTA). The first compared the dose of 64-slice CT to that of dual-source CT, and the other examined coronary CTA dose data from a multicenter trial.
7-tesla MRI pinpoints ankle damage in marathon runners
March 8, 2008 -- VIENNA - Running a 26-mile marathon can cause both painful and painless ankle pathologies, as anyone who has attempted such a feat can attest. New research presented Saturday at the 2008 European Congress of Radiology (ECR) found that 7-tesla MRI scans can give clinicians insight into just how much ankle damage occurs from endurance running.
CAD provides mixed benefits for DR lung exams
March 8, 2008 -- VIENNA - A pair of presentations on Saturday at the 2008 European Congress of Radiology on computer-aided detection (CAD) for digital radiography (DR) reported mixed benefits for the software in detecting lung nodules in thoracic exams. The presenters discussed their experiences with a commercially available CAD product and its impact on radiologist performance in analyzing DR lung studies.
Finland on track to complete national EMR archive
March 8, 2008 -- VIENNA - As Google and Microsoft compete to develop personal health record services in the U.S., Finland is on a fast track to complete a Web-based national electronic medical records (EMR) archive. Scheduled for completion in 2009, the archive will provide near-instant access to medical records by individuals and medical professionals.
ECR NSF studies raise as many questions as answers
March 7, 2008 -- VIENNA - Three studies presented Friday at the 2008 European Congress of Radiology (ECR) reinforced a correlation between gadolinium MRI contrast and renal patients who subsequently developed nephrogenic systemic fibrosis (NSF). But significant questions still remain about the etiology of this mysterious disease.
ECR sessions examine DBT's effectiveness
March 7, 2008 -- VIENNA - A series of presentations on digital breast tomosynthesis (DBT) at the 2008 European Congress of Radiology (ECR) reported encouraging results with the technology. Clinical investigators shared their experiences with DBT systems from four different manufacturers, and reported on the advantages of DBT compared to conventional full-field digital mammography (FFDM).
Automated patient-based contrast application cuts CTA contrast volume, risk
March 7, 2008 -- VIENNA - A work-in-progress application that bases coronary CT angiography (CTA) contrast dose and timing on a patient's individual cardiac output significantly reduces contrast media use and, by extension, the risk of nephropathy, according to a study presented Friday at the 2008 European Congress of Radiology (ECR).
Routine CT scanning is most cost-effective for minor head injuries
March 7, 2008 -- VIENNA - Trying to be more selective about which patients receive a CT scan following minor head injury may sound like a good idea, but most of the major selective strategies are less cost-effective and riskier to patients than just routinely scanning all such patients. That's according to new data presented Friday at the 2008 European Congress of Radiology (ECR).
