Table 2 Results for each of the 6 patients

From: Influence of different treatment techniques on radiation dose to the LAD coronary artery

Patient Nr. Magnitude of IMRT advantage in LAD sparing for both intermediate and large target volume scenarios Would a decision for IMRT have been the preferred option also with regard to heart and left ventricle sparing?
1 IMRT outperformed the other techniques to just below the 25% isodose Yes, IMRT was optimal
2 IMRT outperformed the other techniques to just below the 25% isodose Yes, IMRT was optimal
3 IMRT outperformed the other techniques to just below the 25% isodose Yes, IMRT was optimal
4 IMRT outperformed the other techniques down to the 25% isodose Yes, IMRT was optimal
5 IMRT outperformed the other techniques down to the 50% isodose IMRT and 4-field were very similar regarding total heart, but IMRT was slightly better regarding median and mean left ventricle dose (maximum doses were similar, as were ≤25% isodose levels)
6 IMRT and 4-field very similar, both outperformed AP/PA down to the 50% isodose No, 4-field was best (lowest median heart dose and volume receiving 2 Gy, no disadvantage regarding maximum dose and the various low- dose parameters)
  1. LAD: left anterior descending coronary artery
