灰阶超声造影对膀胱癌分期诊断的价值

Evaluation of the Diagnosis on Staging of the Bladder Cancers by Contrast-enhanced Ultrasound

目的研究灰阶超声造影对膀胱癌分期诊断的价值。方法经肘静脉快速注入SonoVue造影剂后,用灰阶超声造影技术分期诊断膀胱癌18例。结果与病理对照,T1和T4期符均为100%,T2期和T3期符合率分别为80%和83%。T1期膀胱癌分期的诊断符合率高于其他影像学检查,其他各期与其他影像学检查相仿。结论膀胱癌的超声造影检查在分期判断上高于常规超声检查,同时对肿块内部血流灌注的观测又能准确作出诊断与鉴别诊断,此法可以和CT与MRI检查形成互补,提高膀胱癌分期的符合率。

Objective To study the value of the staging of the bladder cancers with the contrast-enhanced ultrasound.Methods After rapid injection of the contrast agent SonoVue through the elbow vein,the staging of images was completed in 18 cases of bladder cancer.Results The results of contrast-enhanced ultrasound were compared with post-operative pathological analysis,the rate of accuracy of diagnosis on T1,T2,T3 and T4 stage was 100%,80%,83% and 100% respectively.The accuracy made by new methods higher than those of other imaging examinations in T1 stage;the other stages were similar to those of other imaging examinations.Conclusion The evaluation of Contrast-enhanced ultrasound on the staging of the bladder cancer is higher than that of the conventional ultrasound examination,while the observation of blood flow in the tumor can make accurate diagnosis and differential diagnosis,this method can be complement each other with CT and MRI to improve the rate of accuracy on the staging of bladder cancer.
