All treatments are planned by a team of experienced nuclear medicine physicians. Y90 SIRT is performed using resin microspheres (SIR-Spheres; Sirtex Medical Ltd.) within 2 weeks of mapping hepatic angiography. Catheter tip placement is the same as that for the 99mTc-MAA injections. In accordance with our institutional protocol, all patients are observed overnight after treatment. They are discharged the following day after Bremsstrahlung planar scintigraphy of the lung and SPECT/CT of the abdomen were performed.
