摘　　要：目的探讨超声造影对壶腹周围癌的诊断及鉴别诊断的应用价值。 方法对33例高度怀疑壶腹周围占位患者进行常规二维超声及超声造影检查，记录病变造影时的增强模式、始增时间、峰值时间等，分别于造影前与造影后静脉相测量病灶大小，并分别与术后切除病灶大小相比较。 结果25例手术病例中22例为壶腹周围癌。22例病灶在注人造影剂后早期均有不同程度的增强，始增时间为9～17s，达峰时间为14～33s。22例手术切除病灶大小与造影前、后所测病灶大小之间均无统计学意义，P〉0．05。超声造影静脉相发现1例肝脏多发转移。 结论壶腹周围癌在超声造影动脉相均有增强，为壶腹周围病变的诊断及鉴别诊断提供了有用的影像学信息。Objective To explore the value of contrast-enhanced ultrasound （CEUS） in the diagnosis and differ： entiation of periampullary carcinomas. Methods CEUS were performed on 33 patients doubted of periampullary lesions. Contrast-enhanced features such as arrival time （AT）, time to peak （TTP）, fill-in pattern were observed. The sizes of the lesions were measured at pre-CEUS, post-CEUS and post-operation. Results Twenty-five patients were confirmed by operation, 22 lesions were diagnosed as periampullary carcinomas. All of these lesions were enhanced during arterial phase of CEUS. The AT was 9s 17s, the TTP was 14s-33s. There were no statistics significance between the pre-CEUS and post-CEUS compared with post operation in sizes of the lesions （all P）0. 05） . One patient with multiple hepatic metastases were found at the venous-phase of CEUS. Conclusions All the periampullary carcinomas had been enhanced at the arterial phase of CEUS. CEUS could offer a high clinic value in the diagnosis and differential diagnosis of the periampullary carcinomas.
