Abstract：Objective To explore the application value of high frequency ultrasound in the diagnosis
of liver cirrhosis and related diseases. Methods 144 patients with liver cirrhosis who underwent
diagnosis and treatment in our hospital from January 2013 to January 2015 were selected to receive
regular ultrasound examination. The patients were treated with high frequency linear array probe as
supplementary ultrasound examination when liver parenchyma showed uneven echo or pathological
changes were suspected on superficial hepatic tissue. In addition, the 15 nodules detected were examined
with real-time high-frequency contrast-enhanced ultrasound. Results Hepatic subcapsular nodules were
found in 92 cases; abdominal varices were found in 28 cases of hepatocellular carcinoma. There were 2
cases of chest wall metastases, 6 cases of umbilical hernia. Among the 15 nodules that were examined
by high frequency ultrasound imaging, 10 were diagnosed as hepatocellular carcinoma (HCC), 2 were
diagnosed as hemangioma, and 3 were diagnosed as regeneration nodules. In response to the real-time
high-frequency ultrasound, the sensitivity of HCC was 80%, the specificity was 28.6%, and the accuracy
was 47.0%. In response to the high-frequency contrast-enhanced ultrasound, the sensitivity of HCC was
90%, the specificity was 71.4%, and the accuracy was 76.4%. Conclusion High-frequency ultrasound
could significantly improve the accuracy in the diagnosis of liver cirrhosis and related diseases.
