Application of fluorodeoxyglucose positron emission tomography in the management of head and neck cancers

Figure 9 Sixty-six year old male was diagnosed with squamous cell carcinoma of the left base of tongue T4aN1M0. He received external beam radiation therapy (70 Gy in 35 fractions) with concurrent cisplatin 100 mg/m² (3 cycles). Positron emission tomography/computed tomography scans were done pre-treatment (A) and at 3-mo (B) and 8 mo (C) post-radiation therapy. Follow-up images show good response to treatment with sustained response at least 8 mo from treatment.
