I interviewed Paul Hsieh on "Radiology in Practice" on 18 December 2014. Listen to or download this episode of Philosophy in Action Radio below.

Most people have seen cool medical imaging devices such as CT and MRI scanners on TV shows. But what do those machines really do? Advanced medical imaging has revolutionized patient care in the past 25 years, allowing doctors to make diagnoses more accurately, quickly, and safely than ever before. Radiologist Dr. Paul Hsieh discussed the basics of modern radiology (x-rays, MRI, ultrasound, and nuclear medicine), how these different tests work, what they show about the human body, and how they help doctors take better care of patients.

Dr. Paul Hsieh is a radiologist in practice in South Denver. He received his MD from the University of Michigan, then completed a residency in diagnostic radiology at Washington University in St. Louis, and an MRI fellowship at Cedars-Sinai Medical Center in Los Angeles. Prior to entering private practice, he was an Assistant Professor of Radiology at Washington University School of Medicine. He is the co-founder of Freedom and Individual Rights in Medicine (FIRM). He has written scores of columns, mostly on health care policy, as well as articles for The Objective Standard. He blogs offbeat tech news at GeekPress.

The mission of Philosophy in Action is to spread rational principles for real life... far and wide. That's why the vast majority of my work is available to anyone, free of charge. I love doing the radio show, but each episode requires an investment of time, effort, and money to produce. So if you enjoy and value that work of mine, please contribute to the tip jar. I suggest $5 per episode or $20 per month, but any amount is appreciated. In return, contributors can request that I answer questions from the queue pronto, and regular contributors enjoy free access to premium content and other goodies.

I'm Dr. Diana Brickell. I'm a philosopher specializing in the application of rational principles to the challenges of real life. I received my Ph.D in philosophy from the University of Colorado at Boulder in 2009. My book, Responsibility & Luck: A Defense of Praise and Blame, is available for purchase in paperback and Kindle. The book defends the justice of moral praise and blame of persons using an Aristotelian theory of moral responsibility, thereby refuting Thomas Nagel's "problem of moral luck."

My radio show, Philosophy in Action Radio, broadcasts live over the internet on most Sunday mornings and some Thursday evenings. On Sunday mornings, I answer questions applying rational principles to the challenges of real life in a live hour-long show. Greg Perkins of Objectivist Answers co-hosts the show. On Thursday evenings, I interview an expert guest or discuss a topic of interest.

If you join us for the live broadcasts, you can ask follow-up questions and make comments in the text-based chat. Otherwise, you can listen to the podcast by subscribing to our Podcast RSS Feed. You can also peruse the podcast archive, where episodes and questions are sorted by date and by topic.
