目的比较彩超、CT和MRI检查原发性胆囊癌影像表现差异及对临床的指导意义。方法 21例胆囊癌患者全部进行彩超和CT检查,9例行MRI检查,全部病例经手术和病理证实。结果彩超、CT、MRI诊断符合率分别为73.7%、68.4%、69.5%。结论彩超、CT、MRI对胆囊癌的诊断正确率较高,彩超结合CT、MRI扫描能无重叠地显示胆囊和胆管局部解剖关系,对于诊断早期胆囊恶性病变彩超有很大优势,了解浸润程度CT、MRI检查帮助较大。二者既存在差异又可相互补充,临床合理选择应用将有助于全面了解病情、指导选择治疗方法。
Objective To compare the differences of color Doppler ultrasonography, CT and MRI in the diagnosis of primary gallbladder carcinoma and their clinical significance. Methods Totally 21 cases of gallbladder carcinoma were examined by color Doppler ultrasound and computed tomography, 9 cases were examined by MRI. All the cases were confirmed by operation and pathology. Results The coincidence rates of color Doppler ultrasound, CT and MRI were 73.7%, 68.4% and 69.5% respectively. Conclusion The diagnosis of gallbladder cancer by color Doppler ultrasonography, computed tomography and magnetic resonance imaging (MRI) is of high accuracy. Color Doppler ultrasonography combined with CT and MRI can reveal the local anatomic relationship between gallbladder and bile duct. It is of great advantage to the diagnosis of gallbladder malignancy with color Doppler ultrasonography. , MRI examination to help larger. The two existing both differences and can complement each other, the clinical application of rational choice will help to fully understand the disease, guide the choice of treatment.
