Researchers found that virtual colonoscopy was reliable for detecting AAA or, more commonly, for ruling out the condition.November 11, 2012Previous PagePage 74 of 258Next PageTop StoriesDigital X-RayCombined fluoride and lead exposure reduces bone health in youthCo-exposure to fluoride and lead exacerbates changes in BMD more than single exposure, suggesting synergistic effects on bone impairment.UltrasoundMedical societies applaud proposed CEUS training recommendationsMRICochrane updates 2013 prostate cancer screening reviewMRIISMRM: fMRI flags brain network failures in fibromyalgia, long COVIDSponsor ContentRadiology is Under Pressure
