Brain MRI accounts for most gadolinium deposits in France
By Frances Rylands-Monk
French researchers have assessed national and regional evolution of gadolinium consumption and found that an increase in MRI machines over the past eight years correlates with an increase in annual gadolinium consumption, but gaps remain in protocols to limit the human and environmental impact.

New MRI scoring criterion helps diagnose prion disease
By Kate Madden Yee
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 on 1 June in JAMA Neurology.

A: A man in his 70s with sCJD subtype VV2 with signal hyperintensity in the body of the left caudate, without evidence of signal abnormality in the putamina and neocortical ribbon. B: A woman in her 60s with sCJD subtype MM1 with signal hyperintensity in the cortical ribbon of both parietal lobes, left greater than right, and left precuneus without evidence of abnormality in the striatum, thalami, and cortical ribbon of the temporal and occipital lobes. C: A woman in her 70s with sCJD subtype MM1 with signal hyperintensity in the precuneus (right greater than left) and right parietal cortex. Images courtesy of JAMA Neurology.

MRI reveals brain changes in radiographer with COVID-19
By Philip Ward
MRI scans of a 25-year-old Italian radiographer 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 29 May.
