For 15(!) years I’ve been teaching introductory #MRI to grad students, and struggled to find a textbook for a wide variety of backgrounds. I'm happy to share an online textbook I created, fully open source (including code for generating figures and plots shown): larsonlab.github.io/MRI-educatio...

If you like this demo, you will love the great demos by @pezlarson.bsky.social that can be found here: larsonlab.github.io/MRI-educatio... (Complete with python code to generate them!)

On a positive note - Happy Pythagorean Triple Square Day :) #math #MATH www.npr.org/2025/09/16/n...

This is a great analysis, especially I like the assessment of different variables on performance in detecting aggressive prostate cancer from MRI important for ML Researchers to see work like this where real world AUCs ~0.7, showing often fundamental challenges in biomedical problems

Advances in 2D materials are enabling atomic-scale resolution in NMR spectroscopy, offering new possibilities for quantum sensing, computing, and communications. doi.org/g9zm6v

Dr. Peder Larson (@pezlarson.bsky.social) will host @ucsfci2.bsky.social's Segmentation Tools Seminar! 🗓 Wednesday, September 24 🕒 3:00 - 4:30 p.m. 📍Genentech Hall Auditorium or Zoom See you there!

It's back to school time! Check out our Magnet Academy site for free science learning resources!

The prostate cancer #MRI field is embracing sharing and leveraging datasets across institutions for training AI models. Preprint of this recently accepted federated learning exploration: arxiv.org/abs/2507.22790

🧵A new COPD diagnostic schema that includes chest imaging, respiratory symptoms, and spirometry identified more high-risk individuals and excluded low-risk ones. #ATS2025 ja.ma/4dp9i30

Nice to see my @ucsfimaging.bsky.social colleague highlighted! Prof. Vu has been innovating higher resolution brain #MRI and getting this technology into the hands of VA doctors

Open source #MRI is thriving at #ISMRM2025 - even the standing room was full at educational session today! 🎉

New layer-fMRI paper showing 3D-EPI with variable sampling density at 0.56mm resolution. Acquired at the Feinbergatron scanner. By Park et al., doi.org/10.1002/mrm....

Well the NIH has cancelled the Women's Health Initiative, the largest study of women in history It has been running continuously since 1991 and has provided massive key knowledge about diseases in women Unreal www.science.org/content/arti...

Happy to walk anyone through this. Our grants are proposed work. We often budget for things like salaries, student tuition, and equipment and consumables (in my field). We work on tight margins - we're often asked to "trim" or modify budgets because program officers try to spread the money.

RT @songihanlab The official flier for the new GRC on Magnetic Resonance and Quantum Information Science, June 14-19, 2026, Southern New Hampshire University, MA. Details TBA over time, looking for support from vendors and institutions www.grc.org/magnetic-res... #NMRevents #NMRchat #NMR 🧲

Two new papers on lung structure and ventilation #MRI with 3D UTE methods, inc patient results My impressions - UTE methods (indirect) not as good as HP Xe (direct, but requires inhaled and hyperpolarized gas) - sequences maturing, processing is critical - great potential for lung dz evaluation

👀👇 "In this risk model, the 93 million CT examinations performed in 62 million patients in 2023 were projected to result in approximately 103 000 future cancers." work from @ucsfimaging.bsky.social

I think this #MRI award from @brukercorporation.bsky.social is a really nice way to recognize novel preclinical sequence work! Past winners include hot topics of ZTE/UTE, hyperpolarized, CEST, MRF, deuterium

Pulseq as a vendor neutral and open source #MRI pulse sequence programming tool is growing with #Hyperpolarized field entering this area now with a couple published papers and repositories. Here’s our latest contribution onlinelibrary.wiley.com/doi/10.1002/... @ucsfimaging.bsky.social

I hosted a mini-hackathon today on #hyperpolarized #MRI software, and very pleasantly surprised with it! Fun discussions, new connections, and I think they made some headway on creating python versions of tools, and building digital metabolism phantoms with anatomy. @ucsfimaging.bsky.social

Impressive work by @mathieuboudreau.bsky.social et al.! Here is the related NeuroLibre preprint that makes replication easy preprint.neurolibre.org/10.55458/neu...

My #Yale colleague Harlan Krumholz explains why the cuts to indirect costs are a disaster for biomedical research in the United States. Want to do something about it? I'll list those who have to hear from us below. Share, recruit friends and family to help. 1/ www.statnews.com/2025/02/08/n....

This is the most relevant article to NIH and research cuts I’ve seen. Imagine if this was today , how many people would be saying “Why are we studying Gila Monsters and their impact on diabetes ? That’s wasted money !” globalnews.ca/news/9793403...

I think the term AI has become so generic that is sometimes feels empty and almost meaningless! I challenge scientists and engineers to be more specific in using terms to define their algorithms and methodology!

Dogs can't operate MRI Machines. But Catscan.

Impressive large (>10k cases) evaluation of #prostatecancer #MRI AI prediction. “An AI system was superior to radiologists using PI-RADS (2.1) at detecting clinically significant prostate cancer and comparable to the standard of care.” pmc.ncbi.nlm.nih.gov/articles/PMC... @thelancet.bsky.social

Together, UCSF Imaging's Drs. Jae Ho Sohn, Yoo Jin Lee, Michael Ohliger & Peder Larson will examine factors affecting image quality in respiratory-triggered free-breathing lung MRI today at #RSNA24. @rsnasky.bsky.social
