| 目的 探讨CEUS诊断脾脏局灶性病变的应用价值。方法 应用SonoVue对25例疑似脾脏病变的患者行CEUS,观察病灶灌注过程。结果 7例脾脏正常,造影剂均匀充填,呈均匀一致的高增强;5例恶性肿瘤动脉期有不同程度增强,实质期均快速退出;13例良性病变中,2例脾血肿、2例脾囊肿、1例脾结核无增强,其余病灶均表现出不同程度增强。与病理结果对照,CEUS诊断脾脏病变的敏感度、特异度及准确率分别为96.97%(32/33)、92.31%(12/13)、95.65%(44/46),均高于二维超声 。结论 CEUS对脾脏局灶性病变的诊断和鉴别诊断有一定价值。 |

| Objective To investigate the value of CEUS in diagnosis of the splenic lesions. Methods Twenty-five patients with doubted splenic lesions were examined with CEUS. The perfusion process of contrast agent was observed. Results After injection of contrast agent, the microbubbles were seen well-distributed in 7 patients with normal spleen. Five malignant splenic lesions enhanced to different extent in the arterial phase, while hypo-enhancement was observed in the substance phase. Among 13 patients with benign lesions, 2 spleen hematomas, 2 splenic cysts and 1 splenic tuberculosis were demonstrated non-enhancement, and other lesions showed enhancement to different extent. According to pathological results, the diagnostic sensitivity, specificity and accuracy of CEUS (96.97%, 92.31% and 95.65% ) were higher than those of conventional ultrasound (60.61%, 46.15% and 56.52% ). Conclusion CEUS can provide useful information for differential diagnosis of focal splenic lesions. |
