Gadolinium persists in brain years after MRI scans March 27, 2015 -- Researchers from the Mayo Clinic can't quite explain the clinical significance, but the discovery of traces of gadolinium in four areas of the brain several years after administration of MRI contrast is enough evidence to warrant further investigation as to the reasons why.
Imaging vendors have options for image processing hardware March 27, 2015 -- When developing new imaging systems, OEMs can choose from many types of computer hardware platforms. Platform selection in turn affects the type of image processing to be used, which then influences the radiologist's work when viewing the medical images. Software architects from advanced visualization developer ContextVision offer some guidance.
AGA retreats on workup for pancreatic cysts found on imaging March 26, 2015 -- The American Gastroenterological Association (AGA) has published new guidelines for managing asymptomatic neoplastic pancreatic cysts detected incidentally during CT or MRI scans. The guidelines retreat from previous advice to follow up these lesions more aggressively, according to an article published in Gastroenterology.
Public reporting does not reduce MRI scans for low back pain March 26, 2015 -- Healthcare regulators looking to reduce overutilization of medical imaging through public reporting of unnecessary procedures may want to find a bigger stick. An analysis in Texas of public reporting of MRI scans for low back pain -- an often unnecessary procedure -- found the initiative to have little effect on procedure growth.
Does access to FFDM priors affect DBT interpretation? March 25, 2015 -- Does having access to full-field digital mammography (FFDM) priors improve radiologists' interpretation of digital breast tomosynthesis (DBT) images? Both exams contribute, but not in the same manner, according to a new study published online in Radiology.
AIUM: Ultrasound bests MRI, mammo in assessing breast tumor size March 25, 2015 -- ORLANDO, FL - Regardless of breast density, ultrasound outperformed MRI and digital mammography for preoperatively assessing breast tumor size, according to research presented on Tuesday at the American Institute of Ultrasound in Medicine (AIUM) meeting.
Brain MRI spots effects of prenatal exposure to air pollutants March 25, 2015 -- MRI has shown reduced white matter in the brains of children who were exposed to toxic air pollution while in utero. This reduction may have led to behavioral and cognitive problems in the first seven to nine years of their lives, according to an article published online March 25 in JAMA Psychiatry.
AIUM: Lung US can handle diagnosis of pediatric pneumonia March 24, 2015 -- ORLANDO, FL - Lung ultrasound can serve as the first-line imaging modality for diagnosing pneumonia in children, avoiding chest x-rays in many cases, according to research presented on Monday at the American Institute of Ultrasound in Medicine (AIUM) annual meeting.
Patients want information about radiation risk March 24, 2015 -- A new study published online in Radiology shows that patients want more information about medical radiation risks, but most would prefer to get it from the doctor managing their care, rather than a radiologist. This means that radiologists need to be more proactive in arming these physicians with information on radiation's risks and benefits.
FDA in hand, EchoPixel preps for launch of True 3D platform March 24, 2015 -- Advanced visualization developer EchoPixel is moving its True 3D Viewer technology to market after receiving clearance from the U.S. Food and Drug Administration for the platform, which creates holographic displays from CT and MRI data.
AIUM: Collaboration needed to propel fetal imaging forward March 23, 2015 -- ORLANDO, FL - Fetal imaging has come a long way, but it will take a fresh mindset and broad collaboration to yield technical advances in the future, according to a presentation on Sunday at the American Institute of Ultrasound in Medicine (AIUM) annual meeting.
How breast centers can make the most of social media March 23, 2015 -- Breast centers have a unique opportunity to educate and inform women in their communities, according to a presentation at the recent National Consortium of Breast Centers meeting in Las Vegas. And one of the best ways to do this is through social media.
HHS publishes proposed rule for stage 3 MU March 20, 2015 -- The U.S. Department of Health and Human Services (HHS) Office of the National Coordinator for Health Information Technology has published a proposed rule for stage 3 of its meaningful use (MU) program for promoting the adoption of healthcare information technology.
Making a Difference as a Sonographer: The perils of job growth March 20, 2015 -- Growth in the number of diagnostic medical sonographer jobs is expected to hit nearly 50% through 2022. But that's not necessarily a good thing, as the increasing popularity of ultrasound puts more strain on sonographers. Find out what you can do to cope in the latest article from Doug Wuebben.
Ultrasound exams present interpretation challenges March 20, 2015 -- Ultrasound requires a unique skill set, according to Dr. Roy Filly, who in this article describes some of the modality's challenges and how they can affect image interpretation. Fortunately, new technologies make it possible to utilize one of the unique aspects of ultrasound: its ability to capture dynamic images.
