Potential risks of IMRT

 Increased need of accurate delineation

Risk of geographical miss because of high conformality, especially in case of positioning uncertainties and motion

 Need for image guidance

High doses in close proximity of OAR  Higher risk of injury

Potential risks

 Low dose radiotherapy bath

Larger volume of normal tissues receive low dose RT

 Interplay effect (lung)
