Check out the @jmri_ismrm editorial with @MerelvdThiel on the interpretation of the DTI-ALPS index in the context of glymphatics.

[Dr Merel van der Thiel @MerelvdThiel]

DTI-ALPS is a commonly used MRI marker for glymphatic dysfunction, but can it distinguish contributions of perivascular diffusivity and axonal degeneration?

@Gerald989 and I wrote an editorial on this topic for JMRI:

Many thanks to all the co-authors that contributed to this work! @jfajansenphd

Recently, our work by Eussen et al. on the core network of the structural covariance network in childhood absence epilepsy was published in @HeliyonJournal! https://t.co/i64Yt1H4iu

[Gerald Drenthen @Gerald989]

Combined, this shows that the structural networks in children with childhood absence epilepsy are less efficiently organized compared to healthy controls and that they are related to cognitive performance.

@champion_gurney @NWO_Science Congratulations Oliver!

With @PaulienVoorter @champion_gurney @MerelvdThiel @jfajansenphd and others.

Last week our work by Voorter et al. on the analysis of multi-b-value diffusion MRI using physics-informed neural networks was published in @mrm_highlights! https://t.co/7XmNJiYeMy

[Gerald Drenthen @Gerald989]

Compared to other least-squares approaches, the physics-informed neural network yields parameters maps with increased CNR, a higher test-retest repeatability and a higher accuracy (the latter based on simulated data)!

Image processing of structural, diffusion-weighted, and functional MRI aids the presurgical work-up for epilepsy by increasing epileptogenic zone detection rate. @MaastrichtUMC @MaastrichtU @Kempenhaeghe @Gerald989 @jfajansenphd https://t.co/158Ev2AyMo

1/15: Epileptic zone detection is one example where advanced MRI techniques have direct clinical impact! A #RadInTraining #TWEETORIAL (@RadITrainEditor) where morphometric analysis, relaxation mapping, and fractional anisotropy are discussed to identify epilepsy causing lesions.

Our new paper is out in @mrm_highlights! In this study we used a genetic algorithm to assess which b-values should be acquired to extract certain metrics from a multi-b-value acquistion https://t.co/GgX1WeDRhU! A thread 👇

[Gerald Drenthen @Gerald989]

Our optimized sampling strategy outperformed other, commonly used, samplings based on simulated and real-world data. Therefore, we showed that the intermediate component can be quantified more accurately using specific b-value sampling schemes!
