MRI reveals brain changes in technologist with COVID-19
June 1, 2020 -- MRI scans of a 25-year-old Italian radiologic technologist who contracted COVID-19 and lost her sense of smell suggest the virus may invade the brain through the olfactory pathway and cause dysfunction of sensorineural origin. This finding was published online by JAMA Neurology on May 29. Read More

MRI aids discovery of new pregnancy contraction
May 28, 2020 -- Researchers using MRI to study blood flow through the placenta discovered a new type of contraction during pregnancy. The authors described the characteristics of the aptly named "utero-placental pump" in a study published on May 28 in PLOS Biology. Read More

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.

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.

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. Read More

COVID-19 neuro findings marked by mental status, stroke
May 26, 2020 -- Neuroimaging features of hospitalized COVID-19 patients can vary, but they are dominated by altered mental status and acute ischemic stroke, according to research published May 21 in Radiology. Read More

Years later, DCIS tied to more imaging but not anxiety
May 26, 2020 -- In the five years after treatment, women with a history of ductal carcinoma in situ (DCIS) are more likely than their peers to undergo breast imaging but not to have anxiety or depression, according to the findings of a study published on May 8 in Breast Cancer Research and Treatment.

fMRI-based machine learning helps predict coma outcomes
May 26, 2020 -- A machine-learning algorithm can predict from resting-state functional MRI (fMRI) data if a patient in a coma after cardiac arrest will regain consciousness, according to a study published online May 21 in the American Journal of Neuroradiology. Read More
