Javery O, Shyn P, Mortele K. FDG PET or PET/CT in patients with pancreatic cancer: when does it add to diagnostic CT or MRI?. Clin Imaging. 2013;37(2):295-301.
OBJECTIVE
Assess the impact of FDG-PET or PET/CT (PI) on pancreatic cancer management when added to CT or MRI (CDI).

MATERIALS AND METHODS
Forty-nine patients underwent 79 PI exams. Discordant findings on PI and CDI were assessed for clinical impact.

RESULTS
Fifteen of 79 PI-CDI pairs were discordant. Ten of 79 PI favorably and 5 of 79 unfavorably altered management. PI favorably altered management more often when ordered for therapy monitoring compared to staging [risk ratio 13.00 (95% CI 1.77-95.30)] or restaging [risk ratio 18.5 (95% CI 2.50-137.22)].

CONCLUSION
PI favorably alters management more often when used for therapy monitoring compared to staging or restaging.
