Comparative analysis of hepatopulmonary shunt obtained from pretherapy 99mTc MAA scintigraphy and post-therapy 90Y Bremsstrahlung imaging in 90Y microsphere therapy

INTRODUCTION Tc macroaggregate albumin (MAA) scintigraphy is routinely used to estimate the hepatopulmonary shunt (HPS) of Y microspheres because of their comparable average particle sizes (20–30 µm). However, the MAA particle size can vary from 10 to 90 µm. Therefore, HPS computed from Tc MAA scint...
