超声造影联合彩色多普勒超声对胰腺肿瘤的诊断价值

Value of Contrast-Enhance Ultrasound and Color Doppler Ultrasonography in the Diagnosis of Pancreatic Tumors

目的探讨超声造影联合彩色多普勒超声对胰腺肿瘤的诊断价值。方法选取了65例胰腺肿瘤患者,按肿瘤类型分为两组,恶性组(42例)和良性组(23例),均采用彩色多普勒超声造影进行检查,观察记录彩色多普勒超声造影诊断胰腺良恶性肿瘤的时相变化、超声表现及造影增强表现。结果恶性组开始增强时间明显晚于良性组(P<0.05),恶性组开始减退时间,造影剂渡越时间均明显短于良性组(P<0.05),两组到达峰值时间相比,无明显统计学差异(P>0.05)。胰腺良性和恶性肿瘤在超声表现上具有明显差异。恶性组造影部分增强表现例数明显多于良性组(P<0.05),两组在全部增强、囊实性的实性部分增强、无增强例数上相比,差异没有统计学意义(P>0.05)。结论彩色多普勒超声造影能明显区分鉴别胰腺良恶性肿瘤,具有良好的诊断能力,值得临床推广使用。

Objective To study the value of contrast-enhance ultrasound and color doppler ultrasonography in the diagnosis of pancreatic tumors. Methods 65 patients with pancreatic tumors were selected and divided into malignant group and benign group according to tumor types. The color doppler ultrasonography was adopted to diagnose pancreatic tumors. The diagnostic value of contrast-enhance ultrasound and color doppler uhrasonography in the diagnosis of pancreatic tumors was evaluated by the changes of time phase, ultrasound and contrast-enhanced ultrasound performance. Results The increase time of malignant group was later than of benign group （ P 〈 0.05 ）. The decreasing time and transit time of contrast agent of malignant group were shorter than that of benign group （ P 〈 0.05 ）. There were no statistical difference in peak time between the 2 groups （ P 〉 0.05 ）. There were significant difference in ultrasound performance between the 2 groups（ P 〈 0.05 ）. There were no statistical difference in ultrasound enhancement degree between the 2 groups （ P 〉 0.05 ）. Conclusion The color doppler uhrasoundgraphy can clearly distinguish between benign and malignant tumors of the pancreas. It has good diagnostic ability. It is worthy of clinical application.
