Ventilation-perfusion scintigraphy for suspected pulmonary embolism, framed with PIOPED/EANM-style interpretation categories — a perfusion-first or ventilation-first facility journey with Maggoo, defect-pattern interpretation, and board-style questions.
Facts follow the pathway selected under Image acquisition (Perfusion first vs Ventilation first). Values are typical teaching ranges (PIOPED/EANM-informed).
V/Q-specific pearls — not a drug-hold list. Click one for the rationale and what happens if it's missed.
Top-down facility view. Maggoo follows the perfusion-first pathway: check-in → Tc-99m MAA injection in the dose room → planar perfusion (6–8 views) or SPECT → optional ventilation → departure.
Ready. Press Play to watch Maggoo's V/Q study.
Synthetic teaching patterns illustrating PIOPED/EANM-style V/Q categories — matched vs mismatched defects, an indeterminate read, and technique artifacts. Select a case for clinical significance.
