Fig. 5. A patient treated with consolidation radiation therapy to the upper para-aortic area and spleen after complete response to chemotherapy for DLBCL. (A) IGRT-IMRT and respiratory gating show very conformal isodose lines around the target with sparing of the heart and kidneys. (B) Respiratory gating takes advantage of increased separation between the heart and spleen with inspiration. (C) Dose-volume histogram shows minimal dose to the heart and other organs at risk.
