EPIDEMIOLOGY, PATHOGENESIS, AND CLINICAL CHARACTERISTICS OF LIVER METASTASES

Liver metastases are among the most common manifestations of advanced malignant tumors and remain a major challenge in modern oncology. Early and accurate detection of hepatic metastatic lesions is essential for disease staging, treatment planning, and improving patient prognosis. This study aimed to compare the diagnostic accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) in the detection of liver metastases. The analysis included 86 patients with suspected liver metastases who underwent both contrast-enhanced CT and MRI examinations. The findings demonstrated that CT provides reliable anatomical assessment and rapid evaluation, whereas MRI shows superior sensitivity in detecting small metastatic lesions because of its excellent soft-tissue contrast and advanced imaging sequences. The combined application of CT and MRI improves diagnostic accuracy and contributes to more effective clinical decision-making. These findings support the complementary use of both imaging modalities in the diagnosis and management of patients with liver metastases.
