Comparison Of Contrast-enhanced Ultrasound And Contrast-enhanced CT In The Differential Diagnosis Of The Benign And Malignant Hepatic Nodules In Budd-Chiari Syndrome

Objective:In recent years, with the increasing case rate of the hepatic nodules in Budd-Chiari syndrome(BCS), such available for the regenerative nodules of benign intrahepatic nodules, can also be used for hepatocellular carcinoma(HCC), Clinical treatments of different nature of the nodules is completely different, the accurate diagnosis of the disease, as well as the differential diagnosis of the benign and malignant hepatic nodules has become a sticking point. By comparing the diagnosis and differential diagnoses of the contrast-enhanced ultrasound(CEUS) and contrast-enhanced CT(CECT) method, my study attempts to discuss the value of both methods in the clinical diagnosis of the hepatic nodules in Budd-Chiari syndrome(BCS).Methods:39 BCS patients with hepatic nodules underwent CEUS and CECT examination separately, through which the perfusion characters of the nodules in different phases were observed. With the pathological result as the golden standard, the sensitivity, specificity and accuracy of CEUS and CECT were compared on diagnosing benign regenerative nodules and hepatocellular carcinoma(HCC) in BCS.Results:Of the 66 hepatic lesions in 39 patients, 21 were diagnosed with HCC, and the other 45 were regenerative nodules in BCS. The sensitivity, specificity and accuracy of CEUS were 81%, 91%, 88%,while the result of the CECT method were 71%, 84%, 80% respectively. The diagnostic efficiency difference between the CEUS and CECT had no statistic significance(P>0.05).Conclusion:The diagnosis and differential diagnoses of the benign and malignant hepatic nodules in Budd-Chiari syndrome(BCS) on CEUS and CECT have high consistency. Because of the convenience and safety of the contrast-enhanced ultrasound method, it can be used as first-line method.
