The Diagnostic Efficacy and Lesion Detection Advantages of 18F-FDG PET/CT and Enhanced MRI in Hepatic Malignancies

Rövid összefoglaló (regiszter, angolul)

Liver disease is a major challenge for global public health, covering a wide range from mild liver dysfunction to serious diseases such as cirrhosis and liver cancer. Globally, the high incidence rate and mortality of liver diseases have led to a huge socio-economic burden, especially in developing countries. Primary liver cancer, especially hepatocellular carcinoma (HCC), is the fifth most common cancer and the third leading cause of cancer death worldwide. In addition, the liver is a common site of metastasis for various cancers, and the occurrence of liver metastasis significantly affects the prognosis and treatment strategies of patients. In this context, accurately diagnosing the nature of liver lesions has become the key to improving patient treatment outcomes. Distinguishing between benign and malignant liver lesions is crucial for avoiding unnecessary invasive interventions and ensuring timely and appropriate treatment. Similarly, timely identification of liver metastases is crucial for the overall management and improvement of survival rates in cancer patients. Traditional imaging techniques such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) have been widely used for the detection and characterization of liver lesions, but they have limitations in diagnostic specificity and sensitivity, limited recognition of specific pathological features, and insufficient ability to detect small metastases. Positron emission tomography/computed tomography (PET/CT), as a widely used fusion imaging technique, combines the metabolic information of PET with the anatomical information of CT, demonstrating unique value in the diagnosis and treatment evaluation of various tumors. However, PET/CT has specific limitations in its application in liver diseases, especially in analyzing small liver lesions and distinguishing between benign and malignant tumors in the context of cirrhosis, which may be challenging. In addition, the radiation exposure caused by CT components is a significant issue that cannot be ignored in PET/CT examinations. Relatively speaking, PET/MR combined with 18F-fluorodeoxyglucose (18F-FDG)provides a new diagnostic possibility, especially when used in conjunction with abdominal-enhanced MR on the same machine, which is expected to further improve diagnostic accuracy. However, despite the theoretical superiority of this technology over traditional methods, the actual degree of improvement, scope of application, and impact on clinical decision-making are still unclear. Therefore, despite high expectations for this technology, it is necessary to conduct a comprehensive study to evaluate the specific benefits of 18F-FDG PET/MR combined with abdominal-enhanced MR in the diagnosis of liver lesions, the particular degree of improvement in diagnostic accuracy, and its potential contribution to improving patient treatment outcomes. This not only helps to validate the practical application value of this technology in the diagnosis of liver lesions but also provides evidence for clinical doctors to optimize and personalize patient diagnosis and treatment plans. The results of this study will provide the scientific basis for future clinical practice, ensuring the effective and cost-effective application of this technology in the management of liver diseases.
