Inter-observer agreement in GTV delineation of bone metastases on CT and impact of MR imaging: A multicenter study

摘要

Background and purpose: The use of Stereotactic Body Radiotherapy (SBRT) for bone metastases is increasing rapidly. Therefore, knowledge of the inter-observer differences in tumor volume delineation is essential to guarantee precise dose delivery. The aim of this study is to compare inter-observer agreement in bone metastases delineated on different imaging modalities.
