Gadolinium levels increase sharply in Tokyo rivers
May 28, 2020 -- The amount of gadolinium found in rivers around Tokyo has risen sharply over the last two decades, in line with a rapid proliferation of MRI scanners and an increasingly aging population that receives more contrast-enhanced exams, according to research published in the May issue of Marine Pollution Bulletin.  Discuss

May 28, 2020 -- A simple patient isolation bag made of hypoallergenic plastic polymer could block COVID-19 infection in the CT suite -- and also improve workflow in radiology departments, according to a study published May 25 in Academic Radiology.  Discuss
Breast MRI's better cancer detection outweighs false-positive 'harm'
May 28, 2020 -- Breast MRI can produce more false positives on initial screening in women at higher cancer risk -- an outcome many consider a "harm" -- but patients and their doctors may decide this is justified by the modality's higher cancer detection rate, according to a study published May 15 in Clinical Imaging.  Discuss
Double-contrast technique could boost MRI for cancer
May 28, 2020 -- A new double-contrast MRI technique in development could help the modality distinguish very small tumors from normal tissue, according to a study published May 25 in Nature Nanotechnology.  Discuss
Quantitative analysis of CT predicts COVID-19 outcomes
May 27, 2020 -- Quantitative computer-aided analysis of chest CT scans can help clinicians predict COVID-19 outcomes in hospitalized patients by providing information on a new metric: compromised lung volume, according to a preprint article published May 23 on Research Square.  Discuss
POCUS helps docs make timely decisions
May 27, 2020 -- Point-of-care ultrasound (POCUS) may help physicians make timely and accurate decisions for patients admitted to the hospital with chest pain or shortness of breath, according to the findings of a pilot study published on May 16 in Ultrasound in Medicine & Biology.  Discuss
