The group is beginning with a study to set pediatric abdominal CT diagnostic reference dose levels based on patient size.May 9, 2012CTFDA targets vendors in push to trim pediatric radiation doseThe U.S. Food and Drug Administration has raised the ante in its drive to reduce pediatric radiation dose, launching a new program that will require manufacturers to consider the safety of children when designing new x-ray imaging devices. Devices that do not comply with the program may have to carry warning labels advising against their use in children.May 8, 2012CTLow-dose CT's bright future, troubled presentThe task at hand in CT radiation dose reduction is pretty straightforward: Record the dose, establish best practices for using it, and then use the right dose for every scan. But in reality these goals are so complex as to be nearly impossible, said Dr. R. Paul Guillerman of Texas Children's Hospital in Houston.May 8, 2012CTAntioxidant formula halves DNA damage from CTA new study in Radiology has found that ingesting a commercially available combination of antioxidants reduces DNA damage by more than half compared to results obtained without antioxidant protection after irradiation with doses comparable to a CT angiography exam.May 6, 2012CTStroke victims not receiving timely imaging"Time is brain" in stroke care -- and far too much of both are being lost, according to a neurologist-led study in Stroke that documents the delays most patients are experiencing in many hospitals before the critical step of brain imaging occurs.May 1, 2012CTCT doses are lower in dedicated pediatric radiology departmentsRadiation exposure from CT was significantly lower when abdominal scans were performed in a dedicated pediatric radiology department compared to scans performed in a department serving both children and adults, researchers report in this month's Journal of the American College of Radiology.May 1, 2012CTARRS: CT radiation far less risky than underlying diseaseThe long-term risk of future cancers associated with CT scans has been under scrutiny for years, but those risks aren't remotely as serious as the risk of dying from the diseases CT is used to diagnose, concluded a study presented on Tuesday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.April 30, 2012Previous PagePage 86 of 258Next PageTop StoriesCTVideo: Perry Pickhardt on CTC, the 'best kept secret in medicine'Perry Pickhardt, MD, offers an overview of the important role CTC can play in colorectal cancer screening.Molecular ImagingExperts issue appropriate use criteria for molecular breast imagingMRIfMRI: Cognitive behavioral therapy positively affects the brainPractice ManagementPost Cures Act, outpatients access radiology reports fasterMRIMRI may help guide brachial plexus surgery
