Kaggle RSNA Challenge 2022 Postmortem

November 13, 2022

I recently participated in my first radiology themed computer vision competition on [kaggle.com](https://kaggle.com). I did not finish well (place 559/883). My best submission was a simple baseline based on the mean of the training. It scored better than every neural net I trained. Nonetheless, I learned a lot about machine learning in general and Kaggle competitions specifically.

How AI Can Really Help Radiologists

November 06, 2022

*„People should stop training radiologists now“* reads a quote by Geoffrey Hinton from 2016, one of the godfathers of Deep Learning. Curt Langlotz, a radiologist from Stanford University is not so pessimistic: *“AI won’t replace radiologists, but radiologists who use AI will replace radiologists who don’t”*. But not only are we radiologist still being trained in 2022, The number of AI tools I use in my day-to-day work as an academic radiologist is negligible.

The Case for Checklists in Radiology

December 25, 2020

According to [Bruno et al. (2015)](https://pubs.rsna.org/doi/pdf/10.1148/rg.2015150023), the most common error in radiology is "underreading", i.e. simply overlooking findings. If you add up all the types of errors that result from overlooking a finding, these account for almost 90% of errors in radiology. Yet it is mostly the increase of knowledge and not the finding of findings that is talked about in the training of radiology residents.
