Radacad is a new initiative from Dr Jeremy Jones, a radiologist from NHS Lothian. Jeremy is a paediatric radiologist, a keen-Radiopaedian and educationalist. He thinks that simulation in radiology is massively under-utilised and wants to change that.
This site is the start of that revolution and drives a simulation-based approach to registrar training that can be linked to an image source. That could be a radiopaedia.org case, but similarly, could be an anonymised case on your PACS. Simulating standard practice is important and should be used where possible.
In Scotland, we have a national PACS and therefore, this system leverages that awesomeness. All cases are anonymised so it's like reporting the study de novo.
