The observer performance trial used exams from a 12-year archive of mobile lung cancer screenings.February 27, 2011CTRadiation exposure linked to illness, not socioeconomic classIndividual medical histories affect how much ionizing radiation poor people accumulate from medical imaging more than their socioeconomic status, according to a mammoth study of poverty and medical practice performed at New York City's Montefiore Medical Center.February 16, 2011Digital X-RayHospitals strongly prefer DR over CR for new x-ray purchasesDigital radiography (DR) is opening up a big lead over computed radiography (CR) as the most popular choice for x-ray imaging in hospital radiology departments in the U.S., according to a new report on hospital-based x-ray equipment and utilization trends.February 9, 2011PACS/VNASurvey tracks pace of cardiac PACS and CVIS integrationHospitals are not just acquiring cardiac PACS and cardiovascular information systems (CVIS). More facilities are integrating images and data to give cardiologists a more convenient presentation of test results that factor into diagnosis and patient monitoring, according to a new report from IMV Medical Information Division.January 25, 2011MRIColored wristbands solve MR safety problem at Mayo ClinicMRI personnel at the Mayo Clinic in Rochester, MN, have learned to look for teal-colored wristbands on patients administered minimal sedation during MRI scans. The colorful wristbands indicate that patients require a nurse's assessment to determine when it is safe for them to go home.January 16, 2011Digital X-RayCAD boosts sensitivity of x-ray lung cancer screeningApplying computer-aided detection (CAD) to digital x-ray images can help radiologists identify significantly more small lung nodules in screening radiographs for lung cancer, according to a study of asymptomatic adults in China.January 9, 2011Digital X-RayDR tomo reduces need for CT to confirm lung cancerPairing low-dose digital radiography (DR) tomosynthesis with conventional radiography eliminates the need for three of every four CT scans typically performed to confirm lung lesions previously suspected on chest radiography, according to a study from the University of Trieste in Italy.December 22, 2010Previous PagePage 5 of 7Next PageTop StoriesMolecular ImagingPET scans tie fast food to altered blood flow in the heartUltraprocessed foods may acutely affect vascular and brain function, researchers report.AIAI boosts rads' identification of incidental PE on CT imagingPractice ManagementHow are technologists dealing with higher vacancy rates?UltrasoundUltrasound screening for vasa previa tied to better pregnancy outcomesDigital X-RayAI could be cost-effective for osteoporosis screening
