Brian Casey[email protected]ConferenceTriple reading boosts breast cancer detection rateVIENNA - Sending suspicious mammograms to a third expert reader can boost the cancer detection rate of a breast screening program by a statistically significant amount, according to a presentation by German researchers at this week's European Congress of Radiology.March 6, 2009Clinical NewsItalian study backs tomosynthesis over DR for lung pathologyA study by Italian researchers has added to the growing body of evidence indicating that digital radiography (DR) with a tomosynthesis capability is superior to conventional DR in detecting pulmonary alterations that could be signs of lung pathology. But tomosynthesis wasn't totally without drawbacks.February 17, 2009Clinical NewsPACS data-mining tool analyzes CR retake ratesResearchers from Spain have developed software that analyzes PACS data to automatically perform quality control analysis of retake rates of computed radiography studies. They believe their QC tool could make it easier for imaging facilities to reduce retakes and improve the overall quality of service.August 4, 2008Clinical NewsSmall lung nodules vex dual-energy DR, study saysEuropean researchers found no statistically significant benefit in the use of dual-energy digital radiography (DR) compared with conventional DR for detecting pulmonary nodules. The predominance of small lung nodules in the multicenter study may have exceeded the ability of dual-energy DR to detect them, they wrote.April 30, 2008ConferenceProspective gating drops cardiac CT radiation doseVIENNA - Prospective gating has emerged as a promising method for reducing radiation dose in coronary CT angiography (CTA) studies. Monday at the European Congress of Radiology (ECR), Italian researchers confirmed previous results in using prospective gating to reduce dose to as little as 2.8 mSv per heart study, while a German group discussed its effort to further refine prospective gating by making it more accurate.March 9, 2008ConferenceMobile DR helps cut ED image transmission timesVIENNA - 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.March 8, 2008ConferenceCAD provides mixed benefits for DR lung examsVIENNA - 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.March 7, 2008ConferenceECR sessions examine DBT's effectivenessVIENNA - 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).March 6, 2008Clinical NewsLower tube voltage leads to reduced dose in pediatric CTSAN FRANCISCO - Radiation dose can be reduced in pediatric CT imaging without compromising image quality by using lower tube voltages, according to CT pioneer Willi Kalender, Ph.D. Dose could potentially be reduced even further if manufacturers tweaked their systems to enable them to scan at lower energies than those commonly used now, he said at yesterday's sessions of Stanford University's International Symposium on Multidetector-Row CT.June 13, 2007Clinical NewsGerman group presents results with prototype breast CT scannerVIENNA - A German research group presented preliminary work on a dedicated breast CT scanner at this week's European Congress of Radiology (ECR). While the group has only studied phantoms with the prototype system, their results so far indicate that the scanner can achieve twice the resolution of conventional mammography at an equivalent radiation dose.March 10, 2007Previous PagePage 19 of 20Next PageTop StoriesMolecular ImagingUnfilled vacancies and disparities persist in nuclear medicineNuclear medicine specialists have high career satisfaction, but unfilled vacancies and career disparities persist, finds a workforce survey by the European Association of Nuclear Medicine (EANM).Molecular ImagingPET develops key clinical role in neuroendocrine tumorsMolecular ImagingPET/CT visualizes complications in patients on hemodialysisCTAll roads lead to outsourcingMRIZonal segmentation with AI shows promise in prostate cancer
