The liver is one of the most common target organs for metastatic disease in cancer patients. Timely diagnosis of structural and functional liver changes is essential for assessing treatment effectiveness, prognosing the disease course, and preventing complications. In recent years, ultrasound elastography has become widely used as a non-invasive method for assessing liver tissue stiffness. This method enables the detection of fibrosis, diffuse parenchymal changes, and focal lesions at early stages. The aim of this study is to analyze the current capabilities of ultrasound elastography in monitoring the liver in patients with cancer and to evaluate its diagnostic effectiveness compared to traditional imaging methods.
