Iranian team presents COVID-19 pediatric stroke case
June 3, 2020 -- A team of researchers from Iran on June 2 published a case study in Radiology that describes incidence of stroke in a child with COVID-19. The case addresses the knowledge gap regarding how SARS-CoV-2 enters the central nervous system and affects the brain.  Discuss
What's the best way to image COVID-19?
June 3, 2020 -- Researchers from Mount Sinai Hospital in New York City have released an overview of imaging modalities used to diagnose and manage COVID-19 pneumonia, trends to watch in artificial intelligence, and a description of nonchest complications from the disease. The review was published June 1 in Radiology: Cardiothoracic Imaging.  Discuss
AI can handle quality assessment of 3D cardiac MRI
June 2, 2020 -- An artificial intelligence (AI) algorithm can automatically assess image quality on 3D whole-heart cardiac MR images, achieving results similar to a human expert, according to research published online May 27 in Radiology: Artificial Intelligence.  Discuss
New MRI scoring criterion helps diagnose prion disease
June 1, 2020 -- A new diffusion MRI scoring scale could improve diagnosis of the prion malady sporadic Creutzfeldt-Jakob disease (sCJD) and compares favorably to cerebrospinal fluid testing, according to a study published June 1 in JAMA Neurology.  Discuss
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.  Discuss
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.  Discuss
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
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
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.  Discuss
