Progress in application of PET-CT in diagnosis and therapy of liver metastasis from colorectal cancer
2010
PET-CT using 18F-FDG is a non -invasive imaging modality which has been recognized as the most important imaging modality in diagnosing, staging, restaging, therapy monitoring and follow-up of cancer patients, especially in metastatic colorectal cancer. PET-CT combines functional and anatomical imaging to improve sensitivity and specificity of whole-body imaging and provides incremental diagnostic value over PET or CT alone. Nowadays, applications of PET-CT imaging in liver metastasis from colorectal cancer mainly included detection and differentiation of malignant and benign liver lesions, determination of appropriate therapeutic strategies and evaluation of treatments.
