【摘要】：目的探讨超声造影(CEUS)在附件区良恶性肿块鉴别诊断中的应用价值。资料与方法对30例附件区囊实性混合肿块或实性肿块患者行经阴道常规超声及经腹部超声造影检查,观察肿块的造影灌注强度和灌注模式,制作时间-强度曲线(TIC)。依据患者手术病理结果分为良性组及恶性组,分析比较两组的TIC形态及造影参数的差异。结果30例附件区肿块,良性组19例,恶性组11例。以正常子宫肌层作为参照,良性组造影剂呈缓慢低或等增强,多由周边向内部灌注,血管走行规则。TIC表现为“缓升缓降”型；恶性组呈不均质快速高增强,多由肿块内部向周边灌注,血管迂曲,走行不规则。TIC表现为“速升缓降”型。造影剂峰值强度(Tp)、曲线下面积(AUC)恶性组明显高于良性组(P=0.000),差异有统计学意义。而达峰时间(Peak),及平均渡越时间(MTT)良性组与恶性组比较,差异无统计学意义(P0.05)。结论超声造影能够更好显示病灶内血流灌注情况,分析附件区肿块的超声造影增强模式、TIC形态及各参数值,有助于提高附件区良恶性肿瘤的诊断及鉴别诊断能力。
[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.
