How prevalent are incidental thyroid nodules on CT?
April 18, 2018 -- Incidental thyroid nodules on CT lung screening scans may be more common than you think, according to an analysis of data from the National Lung Screening Trial (NLST). Researchers found more nodules requiring workup than were originally reported by NLST readers.  Discuss
Report tallies growth in imaging scanners in Canada
April 17, 2018 -- The number of MRI scanners in operation in Canada has grown 65% over the past 10 years, while the number of CT scanners has increased 35% over the same period, according to a new report published by the nonprofit Canadian Agency for Drugs and Technologies in Health.  Discuss
Flexible 3D-printed heart replicates size, texture
April 13, 2018 -- Researchers from Australia and China have created a 3D-printed heart that mirrors the size and texture of real cardiac tissue, with potential clinical applications in patient and medical education, communication among clinicians, and presurgical planning, according to a recent study published in PLOS One.  Discuss
Lung cancer risk model optimizes follow-up CT screening
April 12, 2018 -- How might a lung cancer risk-prediction model improve follow-up CT screening? A model that incorporates patient characteristics and CT data could allow many individuals to skip the first annual follow-up screening exam -- reducing costs and radiation exposure, according to research published online recently in Thorax.  Discuss
Study questions use of whole-body CT for kids with trauma
April 10, 2018 -- Does examining whole-body CT scans of children who present to the emergency department with blunt trauma improve their survival more than evaluating select CT scans of the patients' injured areas? Not in the least, found a study published online April 9 in JAMA Pediatrics.  Discuss
CT dose comes under close scrutiny in Saudi Arabia
April 10, 2018 -- A comprehensive study of diagnostic reference levels (DRLs) in Saudi Arabia has shown that the current levels are comparable with European DRLs, thanks to cutting-edge imaging technology, but patient dose varies between departments depending on scanning mode and protocols used.  Discuss
Muscle mass, adiposity on CT predict breast cancer survival
April 6, 2018 -- Measurements of muscle mass and adiposity drawn from the CT scans of patients with breast cancer predicted their survival better than calculations of body mass index, according to research published online April 5 in JAMA Oncology.  Discuss
CADx volumetry predicts lung cancer recurrence on CT
April 5, 2018 -- Measurements of lung nodule volume on CT scans made with computer-aided diagnosis (CADx) software were more accurate than conventional measurements of nodule diameter in predicting the recurrence of subsolid lung cancer in patients who underwent surgery, according to a recent study published in Radiology.  Discuss
U.S. proposes tariffs on medical imaging scanners from China
April 4, 2018 -- The medical imaging industry has been dragged into the brewing trade war between the U.S. and China. A U.S. federal agency has published a list of 1,300 products imported from China that could be slapped with import tariffs of 25%, with most of the major medical imaging modalities appearing on the list.  Discuss
Does organ-specific CT dose reduction really reduce dose?
April 4, 2018 -- Researchers from Belgium are questioning whether organ-based tube-current modulation in CT chest studies of women really reduces radiation dose. They found that while radiation dose to the breast fell, it increased in other areas, according to a study published on March 27 in Radiology.  Discuss
