April 1, 2020 -- The ultrasound probes and systems that ob/gyn professionals typically rely on for prenatal checkups can also be used for lung imaging in patients with suspected cases of COVID-19, according to an article published on March 24 in Ultrasound in Obstetrics & Gynaecology.  Discuss
Brain images may show 'cytokine storm' from COVID-19
April 1, 2020 -- New CT and MR images of a patient in Michigan with COVID-19 appear to show the impact on the brain of "cytokine storm syndrome," when the body's immune system produces a flood of immune cells that can damage organs. The pictorial report was published online March 31 in Radiology.  Discuss
fMRI finds reason for impulsive binge drinking
April 1, 2020 -- Functional MR images (fMRI) have uncovered decreased connectivity from excessive alcohol intake in part of the brain's basal ganglia that could explain an impulsive person's inclination to continue to binge drink, according to a study published on March 26 in PLOS One.  Discuss
