Figure Lengend Snippet: DVHs of IMRT plans. DVHs of IMRT plans of the case 1 (A) and case 2 (B) shown in Fig. 2. Solid and dotted lines represent the plans with dose constraints for the corticospinal tract (Fig. 2A and C) and those without dose constraints (Fig. 2B and D), respectively. DVH analyses revealed that the doses to the corticospinal tracts and the brainstem were diminished by integrating tractography into IMRT planning, while PTV dose coverages were comparable. Light green, orange, green, purple, pink, and light blue lines represent DVHs of PTV1, PTV2, right corticospinal tract (CST-R), left corticospinal tract (CST-L), brainstem, and optic tract, respectively.
Article Snippet: 39–42 Notably, Kamada et al. confirmed the reliability of diffusion tensor imaging-based tractography by showing a strong correlation between the stimulus intensity of direct fiber stimulation during operation and the distance from the stimulus point to the corticospinal tract on tractography-integrated neuronavigation images.
