Abstract:
We compared customized ITVs obtained with CE-4D-CT imaging (ITV(4D)) with a population-based (ITV(PBC)) in 29 patients (PTs) and evaluated the intra-observer ITV delineation reproducibility in 5 PTs with unresectable pancreatic ductal adenocarcinoma (PDA). The ITV(PBC) was quite different from the ITV(4D), with under/over estimation of volume. Intra-observer volume delineation variability on CE-4D-CT and on a single-phase CE-CT were similar (27.6% vs 24.9%).
