超声造影在脾局灶性病变诊断中的应用价值

Effectiveness of Application of Contrast-Enhanced Ultrasound in the Diagnosis of Splenic Focal Lesions

目的探讨超声造影(Contrast Enhanced Ultrasound,CEUS)在脾局灶性病变良恶性诊断中的应用价值。方法对47例脾局灶性病变进行CEUS,分析CEUS的图像特点,并与最终诊断进行比较。结果在34位患者的47例病灶中,良性病变有29例,恶性病变有18例。CEUS对脾局灶性病变良恶性的诊断敏感度、特异度、精确度分别为96.5%、100%、97.8%;常规超声的敏感度、特异度、精确度分别为79.3%、72.2%、76.6%。造影剂"快出"增强模式在脾良恶性病变中差异具有统计学意义(P<0.05)。结论 CEUS对脾局灶性病变良恶性的鉴别具有重要价值。

Objective To explore the effectiveness of application of Contrast-Enhanced Ultrasound(CEUS) in the diagnosis of splenic benign and malignant focal lesions. Methods 47 cases of spleen focallesions were scanned by using CEUS. The CEUS images were analyzed and compared with the finaldiagnosis. Results The 47 lesions included 29 benign and 18 malignant. The sensitivity, specificity andaccuracy of CEUS were 96.5%, 100% and 96.5% respectively; the sensitivity, specificity and accuracyof conventional ultrasound were 79.3%, 72.2% and 76.6%. The contrast under the fast wash out modeshowed statistically significant difference in splenic benign and malignant lesions (P<0.05). ConclusionCEUS can provide important value in the identification of benign and malignant spleen focal lesions.
