【摘要】：目的探討超聲造影(CEUS)在附件區(qū)良惡性腫塊鑒別診斷中的應(yīng)用價(jià)值。 資料與方法對(duì)30例附件區(qū)囊實(shí)性混合腫塊或?qū)嵭阅[塊患者行經(jīng)陰道常規(guī)超聲及經(jīng)腹部超聲造影檢查,觀察腫塊的造影灌注強(qiáng)度和灌注模式,制作時(shí)間-強(qiáng)度曲線(TIC)。依據(jù)患者手術(shù)病理結(jié)果分為良性組及惡性組,分析比較兩組的TIC形態(tài)及造影參數(shù)的差異。 結(jié)果30例附件區(qū)腫塊,良性組19例,惡性組11例。以正常子宮肌層作為參照,良性組造影劑呈緩慢低或等增強(qiáng),多由周邊向內(nèi)部灌注,血管走行規(guī)則。TIC表現(xiàn)為“緩升緩降”型；惡性組呈不均質(zhì)快速高增強(qiáng),多由腫塊內(nèi)部向周邊灌注,血管迂曲,走行不規(guī)則。TIC表現(xiàn)為“速升緩降”型。造影劑峰值強(qiáng)度(Tp)、曲線下面積(AUC)惡性組明顯高于良性組(P=0.000),差異有統(tǒng)計(jì)學(xué)意義。而達(dá)峰時(shí)間(Peak),及平均渡越時(shí)間(MTT)良性組與惡性組比較,差異無統(tǒng)計(jì)學(xué)意義(P0.05)。 結(jié)論超聲造影能夠更好顯示病灶內(nèi)血流灌注情況,分析附件區(qū)腫塊的超聲造影增強(qiáng)模式、TIC形態(tài)及各參數(shù)值,有助于提高附件區(qū)良惡性腫瘤的診斷及鑒別診斷能力。
[Abstract]:Objective to evaluate the value of contrast-enhanced ultrasound (CEUs) in differential diagnosis of benign and malignant tumors in adnexal region. Materials and methods 30 cases of adnexal cystic solid mass or solid mass were examined by transvaginal conventional ultrasound and transabdominal ultrasonography to observe the perfusion intensity and perfusion pattern of the mass. According to the results of operation and pathology, the patients were divided into benign group and malignant group. The difference of TIC morphology and angiographic parameters between the two groups was analyzed and compared. Results 30 cases of adnexal mass, 19 cases of benign group and 11 cases of malignant group. The normal uterine myometrium was taken as the reference. The contrast medium of benign group was slowly low or equal enhancement, and most of them were perfused from peripheral to internal. TIC showed "slow rise and slow decline" type, malignant group showed uneven rapid and high enhancement, most of them were perfused from the inside of the tumor to the periphery, and the blood vessels were tortuous. The peak intensity of contrast agent was higher in the malignant group than in the benign group, and the difference was statistically significant, and the peak peak time and the mean transit time of the benign group were significantly higher than those in the malignant group, and the mean transit time of MTT in the benign group was significantly higher than that in the malignant group, and there was no significant difference between the malignant group and the benign group, and the mean transit time of MTT in the benign group was significantly higher than that in the malignant group. The difference was not statistically significant (P 0.05). Conclusion Contrast-enhanced ultrasonography can better display the blood flow perfusion in the lesions. The analysis of the enhancement mode of the adnexal masses and the parameters of TIC is helpful to improve the ability of diagnosis and differential diagnosis of benign and malignant tumors in the adnexal region.
