Web• Radiopharmaceutical: Tc-99m-macroaggregated albumin. • Dose: 5 mCi (185 MBq) Check with performing radiologist – may be 2 syringes one with 2 mCi and one with 3 mCi both in 5cc syringe, or 5 mCi in one 3cc syringe. • Technique of administration: Endovascular administration to be done in IR suite. WebThe aim of this study was to assess the role of macroaggregated albumin lung perfusion scans (MAA scans) in the diagnosis of HPS. Methods: MAA scans were performed in 25 patients with HPS, 25 cirrhotic patients without HPS, and 15 hypoxemic subjects with intrinsic lung disease alone. An MAA shunt fraction was calculated from brain and lung … difference between slowking and slowbro
