Summary
Brief summary (as posted)
Histological grade of hepatocellular carcinoma (HCC) is an important prognostic factor affecting patient survival. It has been divided into four grades from I to IV on the basis of histological differentiation. Grade I is the best differentiated consisting of small tumor cells arranged in thin trabeculae. Cells with higher grade are larger and less differentiated with hyperchromatic nuclei and loss of trabecular pattern. Ultrasound is an imaging modality frequently used to evaluate liver tumors because of its convenience, real-time, less expensive and no radiation exposure. However, ultrasonographic evaluation by conventional B-mode image is semi quantitative and subjective. It still cannot replace liver biopsy for the evaluation of HCC. This study is aimed to quantify the image characters of B-mode image and the scatterer properties using Nakagami distribution. Nakagami parameter is a general model to describe the distribution of scatterers. Therefore, the investigators hypothesized that Nakagami parameter may also reflect the histological changes in different grades of HCC. In this study, the resected HCC tumor samples will be collected from the participants who are going to receive surgical resection, and the tumor US images and Nakagami values will be obtained via the single-element ultrasound system. The correlation between the ultrasound backscatter parameter and the differentiation grade will be analyzed.
