Diagnostic Value of PET/CT in Metastatic Liver Cancer

Abstract

There are many diagnostic imaging methods applicable to metastatic liver cancer, including CT, MRI, ultrasound, etc. In some cases, the specificity and sensitivity of these methods are limited, because of the influence of anatomical structures and the lack of blood supply to lesions, making early diagnosis difficult and delaying early treatment. Improving the early diagnosis of metastatic liver cancer and providing a theoretical basis for early treatment are ongoing focuses of medical and clinical medicine research. Positron emission tomography (PET) uses the distribution of positron radiopharmaceuticals in the body to reflect the metabolism of physiological and biochemical features. Fluoro-deoxy-glucose positron emission tomography (FDG PET) uses the increased glucose metabolism in tumor tissue to identify benign or malignant lesions and diagnose them in the early stage as a complement to other imaging technology. The basic principles and application of PET imaging for metastatic liver cancer are briefly discussed in this paper.
