SPECT/CT with ^99mTc-MAA in Radioembolization with ⁹⁰Y Microspheres in Patients with Hepatocellular Cancer

Abstract

SPECT with integrated low-dose CT using (99m)Tc-MAA is beneficial in radioembolization with (90)Y microspheres because it increases the sensitivity and specificity of (99m)Tc-MAA SPECT when detecting extrahepatic arterial shunting. The overall low risk of gastrointestinal complications in radioembolization may therefore be further reduced by SPECT/CT.
