there is no „one size fits all” technique for APBI, the best technique
depends on patient anatomy and tumour location
among BT techniques MIBT is the most flexible and protects best
the normal tissues and OAR-s
IMRT and VMAT can provide highly conformal irradiation at the cost of
large volumes of low doses
MIBT spares better the OAR-s than IMRT except for the heart
