Current Post

This post is based on this new paper published last week, where the authors have described multiple signs that help predict visceral pleural invasion in malignant lung nodules measuring less than 30mm in size.

https://pubs.rsna.org/doi/suppl/10.1148/radiol.231611

It is rare for new signs to be described in radiology and whether these signs will be around 5 years from now, remains to be seen.
