PET with C-11 PiB can assess beta-amyloid brain deposits August 12, 2008 -- PET using carbon-11-labeled Pittsburgh Compound B (C-11 PiB) shows promise for assessing beta-amyloid deposits in the brain and may have a potential role as a diagnostic aid for early Alzheimer's disease, according to research published online in the Archives of Neurology.
US-guided core-needle breast biopsy offers alternative to surgery August 7, 2008 -- Researchers at the Medical University of Vienna and Memorial Sloan-Kettering Cancer Center studied 14-gauge ultrasound-guided biopsy's false-negative and underestimation rates, concluding that the technique provides an accurate alternative to surgical excision for evaluating nonpalpable breast lesions.
PACS data-mining tool analyzes CR retake rates August 5, 2008 -- Researchers 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.
Image tools cut false positives in unprepped VC August 4, 2008 -- Aiming to optimize the results of prepless vitual colonoscopy, researchers have developed a pair of tools to process unprepped CT data and make it easier to read. According to the results of a pilot study, the methods reduced false positives by as much as one-third.
Gestix device gives brain surgeons a hand in the OR July 31, 2008 -- How could the amount of operating room time scheduled for complex brain surgery some day be dramatically reduced? With a wave of the hand -- more specifically, through a graphical user interface that responds to hand motions rather than keyboard or mouse commands. Discuss
FOBT-screened cohort yields too many positives for VC July 28, 2008 -- Virtual colonoscopy (VC) seems a promising way to sort through patients with a positive fecal occult blood test (FOBT), considering the latter's demonstrated low sensitivity and high false-positive rate. But in a screening cohort from the Netherlands, polyps and cancer were so common in FOBT patients that VC hardly seemed worth it.
Smoking during radiation therapy reduces treatment benefit July 16, 2008 -- Patients with non-small cell lung cancer who smoke during the weeks they receive radiation therapy may reduce their overall benefit of treatment. Smoking has a significant negative effect as measured by several factors for assessing radiation therapy's effectiveness, according to study results.
U.S. military to adopt voice recognition technology worldwide July 15, 2008 -- Following the Bush administration's directive for creating a national electronic medical record (EMR) network, the U.S. Department of Defense has initiated a similar effort to have an EMR system in place by 2011 in its Military Health System. The new military EMR will involve the wide-scale deployment of voice recognition software across all military treatment facilities.
