Yttrium 90 radio-embolization is a therapeutic procedure
that delivers radiation directly to hepatic tumors.
Post-procedure PET imaging is a useful tool in detection
of shunting to other organs, and in dose calculations
and quantification. Both of these applications would
suffer from errors due to breathing motion and thus
motion correction is critical. In this study an MR-based
motion correction approach is developed and implemented
using a simultaneous PET/MRI scanner. Phantom and human
data are presented.
