Radiology experts list COVID-19 best practices
March 16, 2020 -- A panel of experts from six institutions has released a list of best practices for radiology preparedness during the coronavirus health crisis. It was published March 16 in the journal Radiology.  Discuss
AI shows high accuracy for detecting COVID-19 on CT
March 16, 2020 -- A newly developed artificial intelligence (AI)-based system is highly accurate for detecting the novel coronavirus disease (COVID-19) on thoracic CT studies, according to research published online March 13 on arXiv.org. It can also quantify and track disease burden.  Discuss
Studies find that coronavirus transmits before symptoms
March 16, 2020 -- The novel coronavirus can spread before patients are symptomatic, according to two new studies, one to be published in the May issue of Emerging Infectious Diseases and the other published March 16 in Science.  Discuss
Can YouTube videos enhance radiology AI performance?
March 13, 2020 -- Pretraining deep-learning models with YouTube video clips can significantly increase the performance of these algorithms in certain radiology applications and help to overcome the challenge of assembling adequate training datasets, according to research published online March 3 in Scientific Reports.

Study outlines 1st person-to-person coronavirus spread
March 12, 2020 -- A study published March 12 in the Lancet journal describes what is believed to be the first person-to-person transmission of the SARS-CoV-2 virus in the U.S. The incident occurred when an Illinois woman who had traveled to Wuhan, China, was symptomatic.  Discuss
ACR recommends sparing use of CT for COVID-19
March 11, 2020 -- CT should not be used as a first-line diagnostic or screening tool for the novel coronavirus disease (COVID-19), according to a March 11 statement by the American College of Radiology (ACR). The statement covers the appropriate use of chest x-ray and CT for the screening, diagnosis, and management of COVID-19.  Discuss
Radiologists distinguish COVID-19 pneumonia on CT
March 11, 2020 -- The novel coronavirus disease (COVID-19) is characterized by CT findings that match features of other pneumonia-causing viruses. But radiologists from the U.S. and China demonstrated that they are well-equipped to differentiate COVID-19 from these other viruses in a new study, published online March 10 in Radiology.  Discuss
3 factors linked to risk of death from coronavirus
March 11, 2020 -- For individuals with the novel coronavirus disease, several factors were associated with an increased risk of death in a new study, published online March 9 in the Lancet journal. Careful observation and blood testing could help clinicians identify these individuals at an early stage, researchers say.  Discuss
Low-dose CT produces no detectable DNA damage
March 10, 2020 -- The debate over the potential harms of CT radiation carries on in a new study published online March 10 in Radiology. Researchers from Japan are reporting that they found no evidence of DNA damage in individuals who underwent low-dose CT scans -- while damage was detectable from standard-dose exams.  Discuss
CT findings for coronavirus may overlap with adenovirus
March 10, 2020 -- Chest CT accurately detected the novel coronavirus disease (COVID-19) in the vast majority of high-risk individuals prior to confirmation by laboratory testing, though it also misidentified COVID-19 for the adenovirus in a small percentage of cases in a new study, published online March 4 in the American Journal of Roentgenology.  Discuss
