Abstract

Abstract: The purpose of this study was to investigate the clinical value of contrast-enhanced ultrasound (CEUS) in the diagnosis of small hepatic nodules. Eighty patients with 88 lesions were selected, and CEUS was performed to analyze the imaging differences between benign and malignant lesions. In CEUS enhancement mode of malignant lesions, the proportion of high enhancement in arterial phase was significantly higher than that in benign lesions, as well as the equal/low enhancement in portal phase and low enhancement in delayed phase (P<0.05). The starting time of enhancement and time to peak (TTP) of malignant lesions were significantly less than that of benign lesions (P<0.05), while the peak intensity (PI) was significantly higher than that of benign lesions (P<0.05). The area under the ROC curve of starting enhancement time, TTP and PI were 0.814, 0.834 and 0.740. In conclusion, CEUS has a good application value in the diagnosis of the nature of small nodules in the liver, which is worthy of clinical use.
