Ob/gyn ultrasound tools work for COVID-19 lung imaging
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
Wuhan nuclear medicine docs give COVID-19 safety advice
March 31, 2020 -- Nuclear medicine specialists from Wuhan, China, the epicenter of the COVID-19 outbreak, have published safety precautions for dealing with patients, staff, and equipment during the pandemic in a March 25 article in the European Journal of Nuclear Medicine and Molecular Imaging.  Discuss
Open-source AI COVID-Net targets COVID-19 on chest x-rays
March 31, 2020 -- Canadian researchers are developing an open-source artificial intelligence (AI) algorithm called COVID-Net for detecting COVID-19 on chest x-rays. They've also made the training dataset available for other researchers.  Discuss
AI-based CAD accurately detects tuberculosis on chest x-rays
March 31, 2020 -- A computer-aided detection (CAD) software application developed with deep-learning technology can detect tuberculosis on chest radiographs at a comparable level to human experts, according to research published online March 26 in Scientific Reports.  Discuss
DBT has lower recall rate in large U.S. study
March 30, 2020 -- Digital breast tomosynthesis (DBT) had significantly lower recall rates than digital mammography in a study published on March 30 in JAMA Network Open. The modality also had higher rates of breast cancer detection, suggesting the reduction in recalls wasn't because of missed cancer cases.  Discuss
CT confirms bathhouse transmission of SARS-CoV-2
March 30, 2020 -- CT exams have confirmed the transmission of the SARS-CoV-2 virus among nine patients who used a bathhouse more than 400 miles north of Wuhan, China, according to a research letter published March 30 in JAMA Network Open.  Discuss
Quality improvement effort slashes CT radiation dose
March 30, 2020 -- A simple and cost-effective intervention led to reductions in CT radiation dose as high as 58% -- without a notable drop in image quality -- for a cohort of nearly 1 million individuals from 100 facilities across the globe in a new study. The findings were published online March 30 in JAMA Internal Medicine.  Discuss
Digital FDG-PET offers insights into hearing loss
March 30, 2020 -- The use of digital PET to measure FDG uptake in the area of the brain devoted to hearing can help diagnose asymmetrical hearing loss and gauge the potential efficacy of a cochlear implant, according to a study published in the March issue of the Journal of Nuclear Medicine.  Discuss
