July 2, 2020 -- Using a deep-learning computer-aided diagnosis algorithm with multiparametric MRI (mpMRI) improves radiologist performance in identifying breast cancer, according to a study published June 29 in Nature.  Discuss
How mammography screening succeeded in Sweden
July 2, 2020 -- Breast screening has been a major success story in Sweden, and the country's experience is often cited as an example of how to implement breast screening on a widespread basis. Dr. László Tabár of Falun Central Hospital explains how it happened.  Discuss
Radiology reentry: Part 2 -- HR and patient scheduling
July 2, 2020 -- As radiology practices begin to reopen amid the COVID-19 pandemic, they have many important variables to consider. In the second of a three-part article series, Rebecca Farrington of Healthcare Administrative Partners discusses human resource management and addresses patient scheduling.  Discuss
ACR, RSNA calls on FDA to hold off on autonomous AI
July 1, 2020 -- Autonomous artificial intelligence (AI) algorithms aren't close to being safe enough to replace radiologists, and the U.S. Food and Drug Administration (FDA) should hold off for now on developing regulatory pathways for autonomous AI in radiology, according to the American College of Radiology (ACR) and the RSNA.  Discuss
Kids with SARS-CoV-2 may develop second inflammation
July 1, 2020 -- Children infected with the SARS-CoV-2 virus may develop asymptomatic or mildly symptomatic COVID-19 but later experience a second, severe inflammatory illness in the brain that shows up as signal changes in the splenium of the corpus callosum on MRI, according to a study published July 1 in JAMA Neurology.  Discuss

July 1, 2020 -- Interval breast cancers diagnosed within one year of a breast screening exam may have unique characteristics that make them particularly aggressive and deadly, according to a study published on June 30 in JAMA Network Open.  Discuss
T1 mapping shows promise for assessing neuroblastoma
July 1, 2020 -- The common MRI technique called T1 mapping -- typically used for patients with heart disease -- could help clinicians evaluate the severity of neuroblastoma in children and the efficacy of treatment, according to results from an animal study published June 28 in Cancer Research.  Discuss
3D ultrasound is effective for measuring blood flow
June 30, 2020 -- Researchers from across the U.S. confirmed the efficacy of 3D color-flow ultrasound for cheaply and reliably measuring blood flow. The findings, which were published on June 30 in Radiology, could help physicians precisely measure blood flow for people with chronic conditions.  Discuss
AI algorithm can help in incidental detection of PE
June 30, 2020 -- An artificial intelligence (AI) algorithm can highlight incidental cases of pulmonary embolism (PE) on contrast-enhanced chest CT exams that were performed for reasons other than to detect PE, according to a presentation at the recent online annual conference of the Society for Imaging Informatics in Medicine.  Discuss
