Title: The Application Value of Ultrasound Contrast in the Screening and Diagno-sis of Patients with High Risk of Liver Cancer
Abstract: Objective To investigate the application of conventional ultrasound(US) and ultrasound contrast for the screening of patients with high risk of liver cancer. Methods 84 patients confirmedly diagnosed with hepatic focal nodular hyperplasia by liver biopsy or postoperative pathological tissue examination underwent both US and ultrasound contrast from June 2013 to June 2015. And an analysis was conducted on the diagnostic accuracy of the two diagnostic methods, the size and number and imaging features of lesions in US and ultrasound contrast of the patients. Results The diagnostic coincidence rate of benign liver lesions diagnosed by US was consistent with that by ultrasound contrast(P0.05). The diagnostic accuracy of liver cancer in ultrasound contrast group was much higher than that in US group( P 0.05). The diagnostic coincidence rate of small tumor with diameter ≤1cm in ultrasound contrast group was much higher than that in US group(P 0.05). Compared with patients with inflammatory pseudotumor of the liver, hepatic focal nodular hyperplasia patients,hepatic hemangioma patients, patients with primary liver cancer and those with metastatic liver cancer had much longer washout time and duration time of ultrasound contrast(P 0.05). Conclusion Compared with US, ultrasound contrast has much higher diagnostic rate of liver cancer, which can distinguish malignant lesions and small lesions as early as possible.Focal hepatic lesions with different characteristics show different enhancement mode in ultrasound contrast. Ultrasound contrast can effectively identify different types of focal hepatic lesions.
