ULTRASOUND TECHNIQUES FOR THE SURVEILLANCE, DIAGNOSIS, AND TREATMENT OF HEPATOCELLULAR CARCINOMA

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Early detection and accurate diagnosis are essential. Ultrasound (US) technology plays a key role in HCC management. Gray-scale ultrasound is non-invasive and cost-effective, providing real-time liver images for detecting abnormalities, especially in high-risk patients. Regular monitoring improves survival rates. Doppler ultrasound techniques assess HCC’s vascular characteristics, aiding treatment decisions. Contrast-enhanced ultrasound (CEUS) offers superior preoperative diagnosis, guided biopsy, and post-treatment monitoring. Three-dimensional CEUS further enhances diagnostic precision. Tissue harmonic imaging improves image quality, distinguishing HCC from benign lesions. Ultrasound elastography measures tissue stiffness, effectively identifying malignant tumors and monitoring treatment response.
