IMRT

First clinical data - 3D-CRT in Patients with small heart volumes irradiated with tangents - IMRT in Patients that would have had large volumes irradiated to high doses with tangents Heggemann et al., IJROBP, 2015

-Noisy data -In both groups temporary depression of heart function parameters -In both groups recovery at 2 years -No relevatn difference between groups

Mean Heart dose is potentially not the best parameter (ASTRO 2015: in RTOG 0617 V45 was the best predictor…….)
