In this edition of IHC Talk, Dr. Mike Arnold (@MArnold_PedPath), Dr. Andrew Bellizzi (@IHC_guy), and Dr. Sanam Loghavi (@sanamloghavi) delve into the exciting (and sometimes intimidating!) world of Artificial Intelligence and its potential to revolutionize pathology. They're joined by special guest Dr. Matt Cecchini (@Path_Matt), a pathologist with a keen interest in AI.
What you'll discover:
- Matt's unorthodox path to Pathology
- The role of IHC in conjunction with AI.
- The need for rigor and consistency in data
- How can the practicing pathologist work with AI to improve?
Get ready for a lively discussion that covers everything from image analysis and mitigating bias to AI agents. The crew dives deep into real-world examples, current tools like ChatGPT, and even the ethical considerations as AI takes on more responsibilities in diagnostic settings. Is AI about to replace pathologists, or can it augment our abilities to deliver better patient care? Listen in and explore the possibilities with this engaging episode!
Thanks to Dr. Cecchini for using Gemini to generate this episode description, and ChatGPT to generate the cover art!
