Autism experts at the Centers for Disease Control and Prevention were neither consulted for the White House’s long-awaited autism announcement nor asked to review a draft of the findings and recommendations.

‘Sick to My Stomach’: Trump Distorts Facts on Autism, Tylenol, and Vaccines, Scientists Say - KFF Health News

The White House’s autism announcement exaggerates links to Tylenol, misleads on vaccines, and sets back the field by ignoring decades of research, scientists say.

The Federal Council wants to cut costs in the ERI sector despite widespread objections. Cuts of over 10 percent per year are planned for the SNSF over the next few years. Above all, this plan jeopardises the innovation potential and competitiveness of the Swiss economy. ⤵️ www.snf.ch/en/9a7Fhnojt...

The SNSF urges against cuts

In its statement on "Relief Package 27", the SNSF speaks out against the proposed annual cuts of 10 percent.

This approach is compatible with most sampling trajectories (linear, spiral, radial,..) and data acquisition strategies (e.g. GRE, EPTI,...).

We show that this new approach (ISME – ‘incoherent sampling of multi-echo data’) improves the reproducibility of R2* and QSM maps by 25%! The R2* maps are also visually sharper, particularly at high resolution.

Antoine Lutti @antoinelutti.bsky.social · 20d

The key idea is beautifully simple: data acquisition is reordered such that the multi-echo data is acquired at different phases of the cardiac cycle. Cardiac-induced noise is then effectively averaged-out in the estimation of R2* or magnetic susceptibility (QSM).

Antoine Lutti @antoinelutti.bsky.social · 20d

To all #MRI officionados out there, we've just published a new paper in MRM to describe a new approach to mitigate the effects induced by cardiac pulsation in relaxometry data from the brain! onlinelibrary.wiley.com/doi/10.1002/...

ISME—incoherent sampling of multi‐echo data to minimize cardiac‐induced noise in brain maps of R2*$$ {R}_2^{\ast } $$ and magnetic susceptibility

Purpose Maps of the MRI parameters R2*$$ {\mathrm{R}}_2^{\ast } $$ and magnetic susceptibility (χ$$ \chi $$) enable the investigation of microscopic tissue changes in brain disease. However, cardiac...

Please repost. The Centre for Functional and Metabolic Mapping is looking for a Preclinical MRI physicist (9.4T and 15.2T Bruker Advance Neo). You will join a team of 14 dedicated staff in Canada's National Ultra-high field MRI platform who also operate 3T and 7T human scanners in the same facility.

Energy?

"Energy"?

Are you fucking kidding me?

"Kennedy questioned the effectiveness of the vaccines…

'You can't control the amount of energy that everybody is getting," he said. "When you give a vaccine, you want to know exactly how much energy is because some people react very, very badly and can get very, very badly injured.'"

I am delighted with this work because it is an important step towards the use of MRI as a non-invasive tool to monitor microscopic brain change in neurological diseases. The assessment of iron distribution is of particular relevance for the study of e.g. #ParkinsonsDisease.

Antoine Lutti @antoinelutti.bsky.social · May 8

- In the substantia nigra, the estimates of volume fraction and intra-cellular iron concentration show a good match with those from histological studies.

Antoine Lutti @antoinelutti.bsky.social · May 8

- From the estimates of the model parameters that describe this signal behaviour, we attempt to characterize the microscopic distribution of the inclusions at the source of this effect.

Antoine Lutti @antoinelutti.bsky.social · May 8

- Using numerical simulations we show that in the substantia nigra (SN), iron-rich dopaminergic neurons can be at the source of this effect

Antoine Lutti @antoinelutti.bsky.social · May 8

- Thanks to extensive preliminary work to improve data quality, we show compelling evidence for the presence of non-exponential behaviour at short echo times, consistent with the effect of microscopic magnetic inclusions (e.g., blood vessels and iron-rich cells).
