Case 2: Radiation therapy plan with IDLs. The patient’s stereotactic body radiation therapy plan is presented. Of note, the total prescription dose (5000 cGy, red IDLs) does not completely cover the tumor and tumor–vessel interface (both in black) given the modifications to zPTV_High. During evaluation, we appreciate that the low dose (3300 cGy, yellow IDLs) approaches complete coverage of the tumor and tumor–vessel interface while the intermediate dose (4000 cGy, orange IDLs) provides near complete coverage of the tumor. The plan appears relatively conformal, with dose pushed appropriately away from the duodenum (white) and bowel structures (olive color wash). Abbreviation: IDL = isodose line.
