超声造影与增强CT检查诊断小于2 cm肝细胞癌的对比研究
Comparison of CEUS and contrast-enhanced CT for diagnosis of <2 cm hepatocellular carcinoma
摘要
Abstract
Objective To investigate the diagnostic value of CEUS for small(<2 cm)hepatic nodules detected by surveillance ultrasound in patients infected with hepatitis B virus (HBV). Methods A total of 77 liver cirrhosis patients with 86 small hepatic nodules(<2 cm)were examined by both CEUS and contrast-enhanced CT.Histopathology based on biopsy or surgery served as the diagnostic gold standard for comparing the sensitivity,specificity,and accuracy of CEUS and CT. Results Sensitivity,specificity,and accuracy were 81.0%,88.6%,and 84.9% for CEUS,similar to the corresponding values of 76.2%,90.9%,and 83.7% for contrast-enhanced CT.Two nodules were correctly diagnosed by CEUS but were misdiagnosed by CT. Conclusion CEUS shows similar ability as contrast-enhanced CT to characterize small nodules (<2 cm)detected by surveillance in patients infected with hepatitis B virus. However,CEUS may be particularly helpful for diagnosing suspicious lesions and for performing follow up.关键词
