Figure 4 Positron emission tomography/computed tomography extends the high dose CTV contralaterally in a patient with a T2N2B base of tongue cancer. A: PET/CT reveals a contralateral level III node (white arrow), and thus, the patient was upstaged as T2N2C; B: An IMRT plan of this patient showing that this node was treated to 70 Gy and contralateral levels II and III were treated to 63 Gy. IMRT: Intensity modulated radiation therapy; PET/CT: Positron emission tomography/computed tomography.
