IMRT minimizes the amount of normal tissue getting high doses
But IMRT does result in larger volumes of normal tissue getting lower
doses (
more fields and more leakage
)
Which is preferable in terms of second cancers?
Small volumes of normal tissue getting high doses (3D-
CRT)
Larger volumes of normal tissue getting low doses
(IMRT)
