Hepatobiliary (HIDA-class) scintigraphy for acute cholecystitis, bile leak, and gallbladder ejection fraction (GBEF) — a living study template using Tc-99m mebrofenin, a facility acquisition journey with Maggoo, interpretation cases, and board-style questions.
Facts follow the protocol selected under Image acquisition (Acute cholecystitis vs Gallbladder EF, top-right toggle). Values are typical SNMMI teaching ranges.
Med holds shared across the acute-cholecystitis and gallbladder-EF protocols. Click a medication for why it matters and what happens if it is not held.
Top-down facility view. Maggoo follows the acute-cholecystitis protocol: check-in → on-table IV Tc-99m mebrofenin → continuous dynamic imaging for 60 minutes → morphine augmentation if the gallbladder has not filled → departure.

Normal filling, acute cholecystitis, low ejection fraction, and bile leak are illustrated with real open-access clinical scintigrams (Radiopaedia.org, CC BY-NC-SA — credited on each case); artifacts/pitfalls use synthetic educational schematics. Select a case for clinical significance and suggested next steps.
Board-style items on preparation, morphine augmentation, sincalide/GBEF, and interpretive pitfalls.
