Five/140 volumes were categorised as very poor DSC agreement with the GS. 28/140 had poor, 53/140 moderate, 50/140 very good and 4/140 excellent (Figure 2). As additional datasets were utilised, DSC increased. A trend toward higher DSC for GTV_MRCT (using 3DCT+MR), ITV_CT (using 3DCT+4DCT) and ITV_MR (using 3DCT+4DCT+MR) were observed.
