- W2393690744 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,(P0.05).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." @default.
