Same day yttrium-90 radioembolization with single photon emission computed tomography/computed tomography: An opportunity to improve care during the COVID-19 pandemic and beyond

Figure 3 Patient with bilobar metastatic breast cancer to the liver. Technetium-99m macroaggregated albumin (Tc-99m MAA) was injected in a split dose fashion to right and left hepatic artery. A: Tc-99m MAA single photon emission computed tomography/computed tomography (SPECT/CT) planning images, using a 140 keV, 20% energy window; B: Bremsstrahlung SPECT/CT images after administration yttrium-90 (Y-90) particles, using a 108 keV, 32% energy window. This results in an image which includes activity from both the previously administered Tc-99m MAA and Y-90 particles, obscuring evaluation; C: Bremsstrahlung SPECT/CT with a 180 keV, 22% energy window which results in adequate filtration of Tc-99m MAA activity and accurate assessment of Y-90 microsphere distribution.
