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
COVID-19 infection can take 5 days to manifest
March 9, 2020 -- People infected with the novel coronavirus may not manifest symptoms for an average of five days, although most will develop symptoms by 12 days after infection, according to a study published March 9 in the Annals of Internal Medicine.  Discuss
AI can accurately quantify emphysema on CT
March 9, 2020 -- An artificial intelligence (AI) algorithm can provide fully automated quantification of emphysema, offering potential as a tool for image-based diagnosis and quantification of emphysema severity, according to research published online March 4 in the American Journal of Roentgenology.  Discuss
AI unlocks screening potential of body CT exams
March 5, 2020 -- Artificial intelligence (AI)-based assessment of body composition biomarkers on abdominal CT exams can more accurately stratify risk for future serious adverse events or death in asymptomatic patients than traditional clinical parameters, according to research published online March 2 in Lancet Digital Health.  Discuss
3 uses for cinematic rendering of brain CTA scans
March 5, 2020 -- Cinematic rendering based on CT angiography (CTA) data can enhance the visualization of complex cerebrovascular anatomy and disease beyond the capabilities of traditional volume rendering, without any added costs, according to an article recently published online in the Journal of Neuroimaging.  Discuss
