What if subtle CT findings you're used to skimming over could actually predict increased mortality and signal the earliest stages of fibrotic lung disease?

Join us as we explore the diagnostic gray zones, progression risks, radiologic pitfalls and whether AI might soon help us see clearly through the fog.
