        [Abstract] Objective To explore the value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of benign and malignant liver disease foci less than 2 cm. Methods A total of 52 patients underwent routine liver ultrasound and CEUS examinations in our hospital from June 2019 to March 2020, and 41 patients with liver disease foci less than 2 cm were selected as the research subjects, and the diagnostic data of the two examination methods were analyzed. According to the probability of benign and malignant, the patients were divided into 5 categories for benign and malignant diagnosis and ROC curve analysis, and the value of the two examination methods in differential diagnosis of benign and malignant liver diseases less than 2 cm was compared. Results Among the 52 liver CEUS patients, 41 patients (78.85%) had liver disease foci less than 2 cm, including 3 patients with 2 foci and 38 patients with a single focus, and a total of 44 foci were observed. A total of 21 malignant foci and 23 benign foci were finally diagnosed. The sensitivity, specificity and accuracy of CEUS were 100.00%(21/21),91.30% (21/23) and 95.45%(42/44),respectively, while those of conventional ultrasound were 85.71%(18/21),60.87%(14/23) and 72.73%(32/44), respectively. The area under the ROC curve of CEUS diagnosis (0.997) was larger than that of conventional ultrasound diagnosis (0.820, P<0.05). Conclusion Contrast-enhanced ultrasound can observe the enhanced and subsided modes of foci radiography throughout the whole process. For small foci with a diameter <2 cm, CEUS has high sensitivity, specificity and accuracy, and strong ability of differential diagnosis, showing a good application prospect.

        肝結(jié)節(jié)通常是由于各種因素影響而引起肝臟纖維組織增生,從而使得肝小梁排列順序紊亂而形成[1]。臨床常見(jiàn)的肝結(jié)節(jié)病灶主要包含肝局灶性結(jié)節(jié)樣增生、肝結(jié)節(jié)狀再生性增生、肝硬化、肝腺瘤及肝部分結(jié)節(jié)樣變[2]。當(dāng)病患機(jī)體出現(xiàn)結(jié)節(jié)時(shí),則表明其肝臟組織已經(jīng)開(kāi)始出現(xiàn)纖維化。因此,及時(shí)對(duì)肝結(jié)節(jié)進(jìn)行有效診斷,并采取相應(yīng)治療措施,對(duì)改善疾病預(yù)后具有積極意義。我國(guó)是肝病大國(guó),每年都有大量患者身受其害。做到早期準(zhǔn)確診斷尤為重要。超聲檢查是肝臟病變首選的影像學(xué)檢查方法,常規(guī)超聲(二維超聲和彩色多普勒超聲)在肝臟病灶的檢出方面具有很高的敏感性,但在病灶的定性方面相對(duì)較弱,尤其是小于2 cm的病灶,因病灶多無(wú)特征性,診斷價(jià)值弱于對(duì)比增強(qiáng)計(jì)算機(jī)斷層成像(Computed tomography,CT)和對(duì)比增強(qiáng)核磁共振成像(Magnetic resonance imaging,MRI)[3]。隨著超聲造影(對(duì)比增強(qiáng)超聲,Contrast enhanced ultrasound,CEUS)技術(shù)的發(fā)展,其在肝臟方面的應(yīng)用越來(lái)越成熟,能夠?qū)崟r(shí)顯示肝內(nèi)病灶的血流灌注過(guò)程,提高定性診斷能力[4]。本研究分析超聲造影對(duì)<2 cm肝病灶的鑒別診斷價(jià)值,現(xiàn)報(bào)道如下。
