Abstract:Objective: To evaluate the usefulness of on-site education for clinical imaging evaluation using quality assurance (QA) testing of surveillance ultrasonography (US) for hepatocellular carcinoma (HCC). Material and methods: Thirty-eight medical institutes underwent on-site education in 2012 for QA testing of clinical imaging evaluation of surveillance US for HCC. Failure rates and mean scores of clinical imaging evaluation for surveillance US of the 2011 survey, the 2012 survey after onsite education and the 20… Show more
“…Son et al [40] reported that the US-3 category demonstrated high specificity, but low sensitivity, for diagnosing HCC and that the visualization score C had a higher false-negative rate than scores A or B. Kang et al [41] reported a high diagnostic yield of US-guided biopsies with visualization scores of A (91.1%) or B (74.5%), but not for those with a score of C (42.9%). In Korea, the US experts of Korean Society of Ultrasound in Medicine are working on standardizing the US scanning protocol for HCC surveillance and educating physicians under the Korean National Cancer Screening Program [42][43][44].…”

Although the overall prognosis of patients with hepatocellular carcinoma (HCC) remains poor, curative treatment may improve the survival of patients diagnosed at an early stage through surveillance. Accordingly, ultrasonography (US)-based HCC surveillance programs proposed in international society guidelines are now being implemented and regularly updated based on the latest evidence to improve their efficacy. Recently, other imaging modalities such as magnetic resonance imaging have shown potential as alternative surveillance tools based on individualized risk stratification. In this review article, we describe the current status of US-based surveillance for HCC and summarize the supporting evidence. We also discuss alternative surveillance imaging modalities that are currently being studied to validate their diagnostic performance and cost-effectiveness.
