Lung x-rays predict mortality in MERS patients July 2, 2015 -- A new study of Saudi Arabian patients with Middle East respiratory syndrome (MERS) found that a simple method of scoring pathology on lung radiographs can be used to predict which patients are at risk of dying, according to an article in the American Journal of Roentgenology.
CMS proposal could lead to more code bundling in 2016 July 2, 2015 -- Radiology could be in store for more code bundling next year, if a proposed 2016 rule issued on July 1 by the U.S. Centers for Medicare and Medicaid Services (CMS) for the Hospital Outpatient Prospective Payment System is any indication. CMS is proposing to continue its restructuring of Medicare codes, and radiology is among its targets.
Does low-level radiation really cause cancer? July 2, 2015 -- The scientific theory that links low levels of radiation to cancer incidence is deeply flawed and cannot be used as a model to predict excess cancer incidence, researchers argue in a paper published in Technology in Cancer Research and Treatment.
Ultrasound helps fine-tune management of arthritis July 1, 2015 -- Ultrasound can be used to identify subclinical disease activity in rheumatoid arthritis patients in remission, enabling them to benefit from more-intensive treatment, according to research presented recently at the European League Against Rheumatism annual congress in Rome.
Animal study raises concern over gadolinium contrast agent June 30, 2015 -- A new animal study published online June 22 in Investigative Radiology has linked one class of gadolinium-based contrast agents to increased deposits of the element in the brains of rats, highlighting recent safety concerns about the use of the MRI contrast medium.
Breast imaging at highest risk for medicolegal claims June 30, 2015 -- It may come as no surprise, but a new study indicates that breast imaging has the highest risk of medicolegal claims compared to other medical imaging exams, at least in Australia, according to a study published online this month in the Journal of the American College of Radiology.
CT radiation dose levels in clinical trial surprise researchers June 29, 2015 -- A group of researchers studying the use of CT for kidney stones were surprised by the radiation dose levels they discovered in their multicenter clinical study. Not only were many doses too high, they also varied widely between centers, concludes a research letter published June 29 in JAMA Internal Medicine.
Group creates 3D printed heart with CT, echo data June 29, 2015 -- In what they are calling a major advance, researchers from Michigan have created a 3D model of a human heart using data from two separate cardiac imaging techniques: CT and echocardiography. They believe that such hybrid 3D models will be more accurate than those created from just one imaging modality.
CT lung CAD may require adjustment from radiologists June 26, 2015 -- Computer-aided detection (CAD) for CT lung exams will be essential in the coming era of population-based lung cancer screening. But radiologists may have to change their way of reading studies to reap its benefits, according to a recent talk by Dr. Geoffrey Rubin from Duke University.
DTI-MRI links maternal obesity to newborn brain growth June 26, 2015 -- Infants born to mothers who are obese display altered brain development, according to a new study in which diffusion-tensor MRI (DTI-MRI) showed reduced white-matter integrity in regions of the infants' brains that are associated with cognitive function.
