Stellenwert der PET/CT zur Bildgebung des kolorektalen Karzinoms

Abstract

To optimally exploit the synergy between morphologic and functional information, FDG-PET should generally be performed as an integrated FDG-PET/CT with a contrast-enhanced CT component in colorectal carcinoma.

18F FDG PET-CT for EBRT Planning in Inoperable Rectal Carcinoma after Receiving Chemotherapy– A

“…The role of PET/CT in radiotherapy planning and response monitoring is under evaluation. Meinel FG et al in their report have recommended a targeted use of PET-CT in cases of unclear M staging, prior to metastasectomy and in suspected cases of residual or recurrent colorectal carcinoma with equivocal conventional imaging (16). Several studies reported that FDG PET is superior to CT in assessing disease with a sensitivity of 84-100% and a specificity of 80-100% in the detection of local recurrence and the accuracy ranges from 74% to 96% (17,18,19).…”
