From: Dosimetric comparison of DIBH and FB for left-sided breast cancer radiation therapy

Distribution diagram of ∆left lung volume and ∆mean OARs dose. Left lung extension volume in DIBH was weakly positively correlated with cardiac and left lung dose reduction, for the heart, R = 0.37 (P < 0.05); for the left lung, R = 0.39 (P < 0.05).
