Values of Spearman coefficients of correlation of Δ value of dose metrics for heart and LAD in FB-RT and DIBH-RT with patients’ related parameters; correlations values for which p value was <0.05 are shown in bold.
| Δ MHD | ΔV20heart | ΔLADmax | |
|---|---|---|---|
| BMI | 0.44 | 0.42 | 0.41 |
| CCD | 0.71 | 0.70 | 0.38 |
| PTV | 0.51 | 0.48 | 0.14 |
| Age | −0.05 | 0.02 | −0.03 |
| Volume of lung on FB | −0.58 | −0.60 | −0.36 |
MHD – mean heart dose, V20heart – volume of heart receiving 20 Gy, LADmax – maximum dose given to left anterior descending artery (LAD), BMI – body mass index, CCD – cardiac contact distance, PTV – planning target volume, FB – free breathing.
