Fig. 2From: 18F-FDG-PET/CT can be used to predict distant metastasis in hypopharyngeal squamous cell carcinomaFrequency curve showing the risk of distant metastases according to the SUVmax of the primary tumor arranged in an ordinal fashion. Patients with a low SUVmax (< 13.9) had a low risk of distant metastasis. The risk of distant metastasis increased sharply as the SUVmax increasedBack to article page
