Value of 18 F-FDG PET/CT in the diagnosis and treatment of colorectal cancer liver metastases / 中华核医学与分子影像杂志

ABSTRACT

18F-fluorodeoxyglucose (FDG) PET/CT offers excellent diagnostic performance on color-ectal cancer liver metastases( CRCLM) in terms of sensitivity and specificity, and can comprehensively identi-fy the presence of extrahepatic metastases and provide valuable information for the treatment decision making. 18 F-FDG PET/CT can also be used in the early assessment of response to CRCLM therapy and survival pre-diction. However, the diagnostic value of PET/CT is limited for lesions with diameter within 10 mm or with activity inhibited strongly by chemotherapy. PET combined with contrast enhanced CT may have potential value in improving diagnostic sensitivity for CRCLM.
