From: Fractionated stereotactic radiotherapy of benign skull-base tumors: a dosimetric comparison of volumetric modulated arc therapy with Rapidarc® versus non-coplanar dynamic arcs

Indices Dynamic arc (DA) Rapidarc (RA) p-value
Dmean (Gy) 3.9 ± 1.9 3.7 ± 1.7 DA vs RA p = 0.41
V30 Gy (cm3) 100.5 ± 99.7 92.6 ± 72.9 DA vs RA p = 0.49
V20 Gy (cm3) 166.1 ± 158.8 184.4 ± 127.0 DA vs RA p = 0.14
V10 Gy (cm3) 425.1 ± 328.8 476.4 ± 226.4 DA vs RA p = 0.09
V5 Gy (cm3) 1056.0 ± 569.7 1264.9 ± 1551.6 DA vs RA p = 0.17
  1. Data presented the mean doses of all patients ± standard deviation. Nb Vx% = minimum x% of prescribed dose received by the volume and Dx% is the minimum dose received by x% of the structure volume
