FDA eyes risks of gadolinium contrast brain deposits July 27, 2015 -- The U.S. Food and Drug Administration (FDA) on Monday announced that it will investigate the risk of gadolinium-based contrast agents in the wake of several recent studies that found gadolinium deposits in the brains of some patients years after they received contrast-enhanced MRI scans.
Study maps CT radiation doses in 100K exams July 27, 2015 -- Have you ever wondered how your facility's CT radiation dose levels stack up against those of other institutions? A study in Radiology describes the experience of researchers from five University of California campuses who measured dose in nearly 86,000 adults and children undergoing common CT scans.
Software aims for realism in echocardiography July 27, 2015 -- A new echocardiography software package released this month analyzes cardiac structure and function pixel by pixel to render detailed functional 3D images that could speed up diagnosis and reduce the number of exams needed in patients undergoing cardiac workups.
Repeat MRI scans due to patient motion mean lost revenue July 24, 2015 -- Having to retake MRI scans due to patient motion can easily cost a hospital upward of $100,000 in lost annual revenue, according to a study published in the July issue of the Journal of the American College of Radiology.
4D parathyroid CT sorts out lesion types July 24, 2015 -- CT scans with 4D image reconstruction can separate parathyroid adenomas and hyperplastic lesions into three distinct lesion types based on enhancement patterns, alerting surgeons to the variations they will find, according to a study in Radiology. The findings also indicate that a three-phase scanning protocol is still needed, the authors believe.
Cardiac CTA study links medical radiation to DNA damage July 23, 2015 -- A study published July 22 in JACC: Cardiovascular Imaging is delivering good news and bad news about medical radiation. The bad news: Researchers found measurable evidence of damage to DNA after cardiac CT angiography (CCTA) scans. The good news: There was no sign of damage at radiation levels lower than 7.5 mSv.
AHRA: Reducing radiation is simple but not easy July 23, 2015 -- Managing radiation dose is a hot topic in healthcare among both clinicians and patients. So how can your facility address concerns about excess dose while also improving patient care? The solution is simple -- but not necessarily easy, according to a presentation this week at AHRA 2015 in Las Vegas.
Neonatal PACS snafu leads to notification software July 23, 2015 -- Neonatal imaging exams are not the studies you want slipping through the cracks. After a PACS software upgrade caused a spike in report turnaround times for neonatal imaging studies, MedStar Georgetown University Hospital developed notification software to alert radiologists that these exams were ready to be read.
Women at high risk for breast cancer don't get needed care July 22, 2015 -- Notifying women at high risk of breast cancer through a patient letter doesn't seem to prompt them to take advantage of the services provided by a high-risk assessment clinic -- in fact, 85% of these women don't attend the clinic, according to a new study published in the Journal of the American College of Radiology.
CT provides fresh revelations about ancient Egypt July 22, 2015 -- CT has reached a level of such sophistication that we can now pinpoint incredible detail inside mummies, turning CT into 3D volumes and then segmenting the data, a leading expert told attendees at last week's "The Curious World of Radiology" seminar.
