Core Tip

Core Tip: Postoperative recurrence remains a major challenge in the management of hepatocellular carcinoma. This study evaluated the complementary diagnostic value of conventional ultrasound and contrast-enhanced magnetic resonance imaging for detecting early recurrence after radical hepatectomy. Contrast-enhanced magnetic resonance imaging demonstrated superior sensitivity for detecting small and deep lesions and vascular invasion, whereas ultrasound showed advantages in detecting superficial lesions and facilitating frequent surveillance. The combined use of ultrasound and contrast-enhanced magnetic resonance imaging significantly improved diagnostic accuracy and detection rates. An integrated surveillance strategy using both modalities may enhance early detection and facilitate timely therapeutic intervention.
