The Treatment Outcome and Radiation-Induced Toxicity for Patients with Head and Neck Carcinoma in the IMRT Era: A Systematic Review with Dosimetric and Clinical Parameters

Figure 4

Comparison of the right and left parotid-gland DVHs of the same head and neck cancer patient (tumor site: oral cavity) for IMRT versus 3DCRT (3-dimensional conformal radiotherapy) technique. The arrows show the relevant DVHs for left and right parotid glands. A and B DVHs for parotids are shifted to the left (C and D) with IMRT techniques resulting in lower doses in the parotid glands (personal archive).
