Ectopic gastric mucosa detection with Tc-99m pertechnetate — a living study template covering the standard and H2-blocker-pretreated protocols, preparation, a facility acquisition journey with Maggoo, interpretation cases, and board-style questions.
Facts follow the protocol selected under Image acquisition (Standard vs Pretreated, top-right toggle). Values are typical SNMMI teaching ranges.
Med holds / avoidances shared across the Standard and Pretreated protocols. H2 blockers, pentagastrin, and glucagon are intentional in-protocol adjuncts (see the Pretreated tab) — not medications to hold. Click an item for rationale and interpretive impact.
Top-down facility view. Maggoo follows the Pretreated protocol: check-in → H2-blocker pretreatment in the dose room → IV Tc-99m pertechnetate → continuous anterior abdominal dynamic imaging → optional lateral/SPECT → departure.
Ready. Press Play to watch Maggoo’s study day.
