Abstract: Objective The aim of this study was to explore the clinical value of perfusion phase analysis of contrast-enhanced ultrasound (CEUS) in the diagnosis of patients with hyperplastic nodules with underlying liver cirrhosis. Methods 100 patients with cirrhosis were encountered in our hospital between June 2017 and June 2020, and all underwent CEUS check-up. The region of interest was drawn, and the peak, time to peak (TTP) and mean transit time (MTT) as well as the regional blood volume (RBV) and the regional blood flow (RBF) were recorded. Results Out of our 100 cirrhotics, the dysplastic nodule (DN) in liver was proven in 54 cases, and small hepatocellular carcinoma (sHCC) was confirmed in 46 cases by histopathological examination; no significant blood flow signals of lesions in DN was 53.9%, while the lesions of sHCC were mainly with low blood flow signals in 48.5%; the lesions in both groups were mainly with low echoes (79.6% vs. 74.2%), with clear boundaries (91.1% vs. 77.3%) and regular morphology (65.4% vs.74.2%); the enhancement features on CEUS images in DN were mainly on low (52.3%), equal (85.9%) and equal enhancement echoes (91.0%) in arterial phase, portal phase and delayed phase, while those in sHCC were mainly with high (86.4%), equal (63.6%) and low enhancement echoes (60.6%), respectively; the peak, TTP and MTT in DN were (46.4±13.5) %, (26.8±3.5) s and (53.3±7.8) s, all significantly different compared with those in sHCC [(58.8±11.3) %, (24.2±4.3) s and (42.5±9.7) s, respectively, P<0.05]; the RBV and RBF in DN in arterial phase were (1562.8±618.3) mL and (1562.8±618.3) mL/s, while in delayed phase were (612.3±95.3) mL and (25.7±6.9) mL/s, significantly different compared with [(3428.6±562.8) mL, (62.5±13.5) mL/s and (385.5±89.6) mL, (18.3±4.7) mL/s, P<0.05] in sHCC; the accuracy, sensitivity, specificity, positive predictive value and negative predictive value by CEUS in diagnosis of DN under cirrhosis background were 87.0%, 87.0%, 87.0%, 88.7% and 85.1%, respectively (Kappa value=0.739). Conclusion The perfusion phase analysis of CEUS could provide objective basis for the diagnosis of DN in patients with underlying liver cirrhosis, which might be of high clinical applicatione.
