超声造影在胆囊癌诊断中的应用价值

目的 探讨超声造影对胆囊癌的诊断价值.方法 回顾分析经手术病理证实的24例胆囊癌的超声造影表现.结果 胆囊癌的超声造影具有一定的强化特点,24例胆囊癌均可见造影增强,病灶较常规超声显影清晰,采用时间-强度曲线分析可以发现病变部位曲线上升支较为陡直,病变峰值强度高于同水平面上相邻肝组织.10例厚壁型胆囊癌中9例胆囊壁快速明显强化,1例胆囊壁在整个造影过程中呈弱增强,增厚的胆囊壁内可见增粗扭曲的血管;8例肿块型胆囊癌快速整体不均匀增强;6例结节型胆囊癌结节内可见造影剂快速进入,不均匀增强.5例胆囊癌伴肝转移造影后检出更多的转移病灶.结论 超声造影强化特征对胆囊癌的诊断有重要的价值,有助于提高胆囊癌的诊断水平.

Application value of the contrast-enhanced ultrasound in diagnosis of gallbladder carcinoma

Objective To study the clinic imaging features and the clinic applications of the contrastenhanced ultrasound(CEUS) in the diagnosis of gallbladder carcinoma.Methods The characteristics of CEUS were reviewed in 24 patients with gallbladder carcinoma proven pathologically. Results After injection of SonoVue, all gallbladder carcinoma of 24 cases showed enhancement and these lesions looked clearer than those in conventional ultrasound.The analysis of time-intensity curve indicated the upslope of curve was steep in the lesions,which was flat in normal liver parenchyma around.In 10 cases of thick wall of gallbladder carcinoma, quick and obvious enhancement was seen in 9 cases, 1 case showed poor enhancement during scanning,but thick and tortile blood vessels could be seen in the thickening wall.Quick and uneven enhancement was been seen in both 8 cases of soft-tissue mass and 6 cases of nodules within gallbladder.Five cases of gallbladder carcinoma with liver metastasis revealed more liver metastasis depend on CEUS.Conclusions CEUS plays an important role in diagnosis and improving the diagnostic accuracy for gallbladder carcinoma.
