No signs of residual gadolinium after MR arthrography
January 29, 2020 -- No signs of residual gadolinium uptake in the brain were found following intra-articular administration of a gadolinium-based contrast agent (GBCA) for MR arthrography in a new study, published online January 25 in Skeletal Radiology. The findings indicate that residual gadolinium may not occur with intra-articular use.  Discuss
Experts reemphasize value of imaging in EVALI diagnosis
January 28, 2020 -- A team of U.S. radiologists and pathologists outlined the current understanding of electronic cigarette, or vaping, product use-associated lung injury (EVALI), the value of imaging in its diagnosis, and lingering questions about the condition in a review article published online January 28 in Radiology.  Discuss
Deep learning could help MS patients avoid GBCA MRI
January 28, 2020 -- With the aid of a deep-learning model, a team of researchers has detected with greater than 70% accuracy active lesions in patients with multiple sclerosis (MS), potentially helping them avoid repeat MRI scans and multiple doses of gadolinium-based contrast agents (GBCAs), according to a study published in the February issue of Radiology.  Discuss
Study supports interval MRI for likely benign findings
January 27, 2020 -- Major cancer organizations recommend interval MRI screenings for women with a breast MRI finding likely to be benign. But are these follow-up screenings of patients categorized as BI-RADS 3 effective for catching cancer? New research shows they are -- to a certain extent.  Discuss
AI enables screening of fracture risk from CT scans
January 27, 2020 -- Patients at risk for osteoporotic fractures can be identified through their routine chest or abdomen CT scans thanks to an artificial intelligence (AI) algorithm tested in Israel, according to research published online January 13 in Nature Medicine.  Discuss
Abnormal chest CT findings anchor coronavirus outbreak
January 24, 2020 -- With at least 800 cases confirmed worldwide, concerns over the latest coronavirus outbreak continue to escalate. Researchers from China report on the epidemiological and radiological characteristics of the novel virus and clinical outcomes of the first set of infected individuals in two studies that were published January 24 in Lancet.  Discuss
MRI shows air pollution effect on kids' brain development
January 24, 2020 -- Air pollution is not only bad for the lungs, it could be bad for the brain as well -- especially in children. Brain MR images showed reduced gray-matter volume in kids who were exposed to high levels of traffic-related air pollution since birth, according to a January 24 study in PLOS One.  Discuss
CT, MRI for lower back pain still prevalent in ED
January 24, 2020 -- The rate of CT and MRI scans for back pain remained steady from 2001 to 2016 despite efforts to curtail unnecessary imaging tests in emergency departments (EDs) for lower back pain, according to a study published in the February issue of the American Journal of Roentgenology.  Discuss
3D printing helps mummy speak from beyond the grave
January 24, 2020 -- Have you ever wondered what it would be like to hear a mummy speak? It's now possible thanks to the magic of CT and 3D printing technology, which has enabled the re-creation of the distinct voice of an ancient Egyptian who's been dead for centuries. The process is detailed in a January 23 article in Scientific Reports.  Discuss
Elastography shows high reproducibility in breast lesions
January 24, 2020 -- Two different ultrasound elastography techniques -- strain elastography and shear-wave elastography -- showed high interoperator reproducibility when scanning breast lesions in a new study, published on January 21 in Ultrasound in Medicine and Biology.  Discuss
