Can contrast-enhanced CT determine whether a liver nodule is benign or malignant?

Enhanced CT usually refers to contrast-enhanced CT. Contrast-enhanced CT can generally indicate whether liver nodules are benign or malignant, but it is typically considered an auxiliary method. The specific analysis is as follows:

Contrast-enhanced CT involves targeted imaging of suspicious areas after intravenous injection of a contrast agent, based on initial non-contrast CT scans. This helps improve diagnostic accuracy and clarify the nature of hepatic space-occupying lesions as benign or malignant. Liver nodules often develop due to severe liver damage caused by chronic hepatitis B virus infection, indicating that the patient's liver has already undergone fibrosis. With contrast-enhanced CT, the relationship between the nodule and surrounding tissues can be clearly observed, local lesion changes can be precisely evaluated, and a preliminary assessment of the nodule's benign or malignant nature can be made.

However, contrast-enhanced CT alone cannot provide a definitive diagnosis. It serves as an adjunct to diagnosis. Patients are advised to undergo biopsy according to medical advice, with final confirmation achieved through histopathological examination combined with clinical symptoms, physical examination, and comprehensive analysis.
