Consensus margin and margin deviation for a metastasis in the iliac crest showing cortical disruption: CT and overlaid contours for a patient with a metastasis in the iliac crest. The GTV and STAPLE CTV are represented by the solid green and red contours, respectively; the expert contours are dotted. The directions of potential intraosseous and extraosseous extension are indicated by the cyan and yellow vectors, respectively. These directions are termed superior-posterior (SP), inferior-anterior (IA), superior-right (SR), anterior-right (AR), and posterior-right (PR). The text annotations report the consensus margin (mm) followed by the margin deviation (dimensionless) for each direction
