Example of discordance between DVHs and QVH analyses. a Coronal DPost-treatment-R image, showing doses ranging from 20 to 40 Gy in the NTL. b Coronal DPredicitve-D image, showing doses ranging from 20 to 60 Gy in the NTL. Areas covered by the different isodoses are similar, but their patterns are different. c DVHs obtained for patient’s NTL at predictive and post-treatment dosimetry, showing the similarity between the two dosimetries. d Corresponding QVH showing a poor agreement (QF = 0.34) between the two dosimetries
