ABSTRACT
Objective To investigate the diagnostic value of contrast-enhanced ultrasound (CEUS), and compare it with contrast-enhanced CT(CECT). Methods Eighty-one focal liver lesions were evaluated with CEUS and CECT, diagnostic value of two modalities were calculated, vaseularity manifestations of two modalities in arterial phase were compared. Results The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CEUS were 96.6 %, 86.9 %, 94.9 %, 90.9 %, 93. 80%, respectively, and the diagnostic value of CECT were 98.3%, 82. 6%, 93.4%, 95.0%, 93.8%, respectively. Among all the metastasis, hypervascular manifestation lesions in arterial phase of CEUS and CECT were 72% (18/25) and 32% (8/25)( P <0.05). Conclusions The diagnostic value of CEUS and CECT in focal liver lesions are comparably satisfying,and there is no significant difference between them, the combination use of two modalities would improve the diagnosis performance. CEUS can show more hypervaseular metastasis than CECT in arterial phase.
