Fig. 4From: Prognostic value of 18F-fluorodeoxyglucose positron emission tomography in patients with small hepatocellular carcinoma treated by radiofrequency ablationComparison of metastatic recurrence-free survival rates between 18F-fluorodeoxyglucose positron emission tomography positive and negative groups. Metastatic recurrence-free survival was significantly shorter in the 18F-fluorodeoxyglucose positron emission tomography positive uptake group than in the negative group (p < 0.001)Back to article page
