Is Ignorance Bliss? Full-Body MRI, PI-RADS Confusion, and What AI Really Sees with Andrew Lacy

Stop waiting for symptoms and start optimizing your longevity. In this episode, Dr. Geo sits down with Andrew Lacy, CEO of Prenuvo, to discuss how full-body MRI is fixing a reactive healthcare system that acts as a "false negative factory" during annual physicals.

From the psychology of "Patient Stimulated Anxiety" to the technical reality of AI in radiology, this conversation provides a science-based blueprint for middle-aged men looking to perform better with age.

Inside This Episode:

The PSA Red Flag: Why a PSA above 1.0 at age 45 is a critical warning sign.
PI-RADS Discordance: A case study on why one radiologist sees a "4" while another sees a "2".
Prenuvo’s Method: Understanding non-contrast multiparametric MRI for risk stratification.
The AI Reality: Why AI is currently a "quantitative second look" rather than a replacement for radiologists.
Life-Saving Detection: Why MRI is phenomenally effective at catching pancreatic cancer early.
Test, Don't Guess: Shifting from a "head-in-the-sand" mindset to informed lifestyle changes.
