超声造影和增强CT诊断胆囊隆起性病变比较

Comparison of Contrast-enhanced Ultrasound and Contrast enhanced CT in Diagnosis of Gallbladder Elevated Lesions

目的:探讨实时超声造影和增强CT诊断胆囊隆起性病变的价值。方法:对66例胆囊隆起性病变进行超声造影及增强CT检查,观察胆囊壁及胆囊隆起性病变的不同时相的增强特征。结果:以手术病理结果为诊断金标准,66例中胆囊息肉21例、腺瘤10例、胆囊腺肌增生症9例、胆囊癌26例,超声造影准确率分别为88%、86%、95%和91%,增强CT准确率分别为83%、79%、95%和91%,超声造影和增强CT对胆囊隆起性病变的诊断准确率分别为80%和74%(P>0.05)。结论:超声造影对诊断胆囊隆起性病变比增强CT更有优势。

Objective To study real-time contrast-enhanced ultrasound and contrast-enhanced CT in thediagnosis of gallbladder elevated lesions.MethodsSixth-six cases of gallbladder elevated lesions were per-formed by contrast-enhanced ultrasound and contrast enhanced CT, observation of gallbladder wall and gallblad-der elevated lesions and different phases of enhanced features.ResultsConfirmed by operation and pathologyin 66 cases, 21 cases were gallbladder polyps and adenoma in 10, gallbladder adenomyomatosis in 9 and gall-bladder carcinoma in 26. Contrast-enhanced ultrasound accuracy was 88%, 86%, 95% and 91% alternatively inthe four groups, and contrast-enhanced CT accuracy was 83%, 79%, 95% and 91%. Contrast-enhanced ultra-sound and contrast-enhanced CT in the diagnosis of gallbladder elevated lesions of the accurate rate was alterna-tively 80%（53/66） and 74%（49/66）（P〉0.05）.ConclusionContrast-enhanced ultrasound has more advan-tages than Contrast-enhanced CT in the diagnosis ofgallbladder elevated lesions.
