Nuclear Medicine in 90 Minutes

Start here

This is a guided tour, not a textbook chapter. Read these seven pages in order and you'll understand what nuclear medicine actually is, how it reads the body's biology and acts on it, and why the field is growing quickly right now. Each link opens the page in the atlas — follow them top to bottom, then come back here for the next step.

The path

1 · Why Nuclear Medicine: what the field does, and why it is growing quickly. Start here for the "why."

2 · Molecular Imaging & the Theranostic Pair — how one molecule can carry either a diagnostic or a therapeutic isotope. This is the concept everything else builds on.

3 · FDG PET/CT in Oncology — the workhorse scan you'll see most: sugar metabolism as a map of cancer throughout the body.

4 · Theranostics — Overview — the see-and-treat loop in practice: image the target, treat it, measure the dose, reassess.

5 · ¹⁷⁷Lu-PSMA-617 — the flagship therapy: a PSMA PET lights up prostate cancer everywhere, then a matched drug delivers radiation to those exact deposits.

6 · AI & Machine Learning in Nuclear Medicine — why this quantitative, data-rich specialty may be the one AI transforms most.

7 · Becoming a Nuclear Medicine Physician — the training pathways, including routes through diagnostic radiology, if the see-and-treat loop lit the bulb.

Where to go next

If this sparked something, the natural next step is the Resident Core Curriculum for a structured deeper dive, or the Theranostics Deep-Dive if the therapy side is what grabbed you. Explore the Field & Future chapter for the careers and workforce picture — the field is hiring faster than it can train.
