PURPOSE To evaluate the efficacy and safety of ultrasound (US)-guided percutaneous argon-helium cryoablation for hepatocellular carcinoma (HCC) and determine appropriate indications. METHODS We reviewed outcomes of 300 HCC patients who underwent US-guided percutaneous cryoablation. RESULTS Overall, 223 tumors (mean diameter 7.2 ± 2.8 cm) in 165 patients(More)
BACKGROUND Previous studies suggested that the racial differences in U.S. suicide rates are decreasing, particularly for African Americans, but the cause behind the temporal variations has yet to be determined. This study aims to investigate the long-term trends in suicide mortality in the U.S. between 1983 and 2012 and to examine age-, period-, and(More)
In this paper, a novel complex mask for the implementation of fractional differentiation is deduced. By the combination of fractional differentiation and integration, a new compound derivative is proposed, in which the fractional-order derivative mask is employed. The compound derivative, together with the complex mask, is applied to edge detection, forming(More)
BACKGROUND Accumulating evidences have suggested that percutaneous cryoablation could be a valuable alternative ablation therapy for HCC but there has been no large cohort-based analysis on its long-term outcomes. METHODS A series of 866 patients with Child-Pugh class A-B cirrhosis and HCC within Milan criteria who underwent percutaneous cryoablation was(More)
