IMRT

“Involved-Site” Radiotherapy

• The concept of ISRT was developed on the basis of the INRT concept • The irradiated volume is significantly smaller than with IFRT • If prechemotherapy imaging is available, but image fusion with the postchemotherapy planning CT scan is not possible  ISRT • If no prechemotherapy imaging is available  IFRT
