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. Read More
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. Read More
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. Read More
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). Read More
Dual-source CT edges into cardiac SPECT turf
March 6, 2008 -- U.S. researchers will use this week's European Congress of Radiology in Vienna to present research that shows dual-source CT making inroads into cardiac functional imaging, an area currently dominated by SPECT. The study moves dual-source coronary CT angiography closer to the holy grail of cardiac imaging -- a test that performs both morphological and functional analysis in a single scan. Read More
Hybrid lung segmentation software boosts performance
February 13, 2008 -- A lung segmentation algorithm that combines the advantages of standard and more sophisticated approaches yields fast and accurate results, according to researchers from the University Medical Center Utrecht in the Netherlands. Read More
Model finds polyp surveillance effective for cancer prevention
January 21, 2008 -- The risk of developing colorectal cancer from polyps found at virtual colonoscopy but left unresected is not precisely known, and the practice of polyp surveillance is still controversial. But a new study concludes that the low likelihood of advanced neoplasia combined with the high cost of colonoscopy argue against the immediate removal of small lesions. Read More
Coronary CTA study aims for lowest dose
January 11, 2008 -- A study from Switzerland concludes that low-dose prospectively gated coronary CT angiography (CTA) is both feasible and promising, but not without wrinkles. Relying on prospectively triggered gating and some of the lowest radiation doses yet achieved for prospectively gated coronary CTA, the team reported that 95% of all coronary segments achieved diagnostic image quality, but image quality was very dependent on heart rate.
