Study Type, Agent, and Dose?

Dose this delayed image confirm the Dx?

Normally Functioning Peritoneal-Venous Shunt

Agent: 99mTc-Macro-aggregated albumin (MAA)

Adult Doses: 5 mCi by paracentesis

Critical Organ: Lung

Notes:

• Shunts (e.g., LeVeen or Denver) may be placed between the peritoneum and the venous system, to help manage intractable ascites
• Radiopharmeceutical (MAA) is instilled into the peritoneum; any activity within the lungs (from the MAA) means the shunt is functioning normally
