Abstract
Objective To investigate qualitative diagnostic value of contrast-enhanced ultrasound (CEUS) technique of focal liver lesions (FLL). Methods CEUS was performed in 86patients with FLLS. Contrast agent SonoVue and contrast tuned imaging technology were used. Contrast-enhanced sonographic features of FLL were analyzed. Results Initaial enhancement time of malignant FLLs ( 12.5 ± 2. 2 ) s was significantly lower than that of benign FLLs ( 15.4 ± 2.8 ) s, ( P ＜ 0. 05 ). 54 ( 96.4 ％ ) malignant lesions presented enhancement in arterial phase and hypo-enhancement in late phase ,where as 27 (90. 0％ )benign lesions showed enhancement in arterial phase and persistent hyper-oriso-enhancement until late phase. The malignant lesion was estimated by a given criterion of presenting low-enhancement in late phase, the sensitivity, specificity, positive and negative predictive values and accuracy with CEUS in the diagnosis of FLLs were 96.4％ ( 54/56 ) ,90. 0％ ( 27/30 ) ,94. 7％ ( 54/57 ) , 93.1％ ( 27/ 29 ) and 94.2％ ( 81/86 ), respectively. Conclusion CEUS is a useful technique in the qualitative diagnosis of FLL.关键词
