Exogen hopes to take the concept to the next level by applying it to the entire healthcare enterprise.June 17, 2008Radiation Oncology/TherapySalvage radiotherapy for recurring prostate cancer enhances survival oddsSalvage radiation therapy can help boost survival rates for certain groups of prostate cancer survivors who show signs of recurrence after surgical treatment, according to a study by Johns Hopkins University researchers in the Journal of the American Medical Association.June 16, 2008BreastFDA proposes easier regulatory path for FFDM systemsThe U.S. Food and Drug Administration is proposing changes to the way it regulates full-field digital mammography (FFDM) systems. The move should make it easier and less costly for mammography vendors to bring FFDM systems to market when the new rules are scheduled to go into effect in 2009.June 9, 2008PACS/VNAGE and UPMC form Omnyx to develop PACS for pathologyGE Healthcare of Chalfont St. Giles, U.K., and the University of Pittsburgh Medical Center (UPMC) announced the formation of a new company called Omnyx to develop digital acquisition, image management, and storage systems for pathology applications.June 4, 2008PACS/VNAWho owns PACS -- Radiology or IT?Should radiology or the IT department take responsibility for managing PACS in a hospital? It depends on the facility's corporate culture and the level of sophistication of the IT department, an animated "debate" at the 2008 Society for Imaging Informatics in Medicine (SIIM) meeting concluded.June 3, 2008Clinical NewsGlobal radiation dose higher than necessaryInitial results of a multinational research study on x-ray quality control and patient dose conducted by the International Atomic Energy Agency (IAEA) reveal that up to 50% of x-ray exams performed in less developed nations are of substandard quality. What's more, many patients in these countries are being exposed to unnecessary radiation doses due to the need to repeat procedures.June 2, 2008Previous PagePage 83 of 88Next PageTop StoriesCTMachine learning plus CT helps assess severity of COPDA machine-learning model based on chest CT images accurately predicts lung function, which can help clinicians diagnose and assess COPD.UltrasoundActive thyroid surveillance effective, beneficial for older patientsMolecular ImagingFES-PET shows promise staging women with invasive lobular cancerCTStructured CT reporting tool may aid hernia detection after bariatric surgeryMRIHigher ventricular and atrial heart volumes boost cardiac disease risk

SUVR images were corrected for partial volume effects and masked with the gray matter mask used for volume of interest delineation. Overall tau accumulation is comparable between the late-life depression (LLD, middle column) and non-depressed cognitively unimpaired comparison (HC, left column) groups, while abnormal tau accumulation, which is most pronounced in the mesial temporal lobe, can be seen in the mild cognitive impairment due to Alzheimer's disease group (right column).
