Myocardial perfusion SPECT for CAD evaluation — a same-day rest→stress (or stress-only) facility journey with Maggoo using Tc-99m sestamibi, medication holds, reversible-ischemia vs fixed-infarct interpretation, and board-style questions.
Facts follow the protocol selected under Image acquisition (Rest → stress vs Stress only, top-right toggle). Values are typical teaching ranges.
Held medications shared across the rest→stress and stress-only protocols. Click a medication for why it matters and what happens if it is not held.
Top-down facility view. Maggoo follows the same-day rest→stress protocol: check-in → resting Tc-99m sestamibi (lower dose) → uptake wait → rest SPECT → stress test on the treadmill/pump with higher-dose injection at peak stress → uptake wait → stress SPECT → branch: attenuation / prone imaging? → departure.

Open-access clinical MPI images (Radiopaedia, CC BY-NC-SA): extracardiac FOV findings (liver metastasis, thyroid adenoma) plus attributed stress/rest stills for reversible ischemia and fixed infarct. Synthetic schematics remain for normal perfusion, balanced ischemia, and attenuation-artifact cards.
Board-style items on stress-agent pharmacology, medication holds, gated SPECT, and stress/rest interpretation pitfalls.
