A pilot study of early 18F-FDG PET to evaluate the effectiveness of radiofrequency ablation of liver metastases

AJR Am J Roentgenol. 2007 Nov;189(5):1199-202. doi: 10.2214/AJR.07.2126.

Abstract

Objective: The objective of our study was to collect pilot data about the use of FDG PET within hours after radiofrequency ablation (RFA) of liver metastases.

Conclusion: Total photopenia on early PET can potentially be regarded as a macroscopic tumor-free margin; focal uptake can be regarded as macroscopic residual tumor.
