Abstract Preview: Purpose: Relative to planar imaging, MAA-SPECT/CT offers more reliable lung shunt fraction (LSF) and lung mean dose (LMD) estimates in 90Y radioembolization. But lung truncation in SPECT/CT can limit ...

Abstract Preview: Purpose:
This study evaluates synthetic planar imaging (synP) from SPECT projections against conventional planar imaging, focusing on detectability, spatial resolution, and feasibility. SynP allows...
