简要总结
This prospective cohort study is designed to investigate and to compare the diagnostic performance of contrast-enhanced ultrasonography (CEUS) and multidetector computed tomography (CT) for gallbladder cholesterol polyps, adenoma and gallbladder cancer.
详细描述
In this study, investigators aimed to investigate the diagnostic performance of CEUS and high resolution CT (HRCT) for the preoperative differential diagnostic accuracies of gallbladder polypoid lesions.

研究组 & 干预措施
gallbladder polyps patients
All patients with a gallbladder polypoid lesion visited our department, diagnosed by conventional transabdominal US, were enrolled in this study.
Of these patients, we excluded: (1) gallbladder polyp with a diameter less than 10 mm. (2) lesions highly suspected to be cancer due to visible metastasis. (3) allergy to contrast agents and cannot received CT or CEUS examination. (4) women in pregnancy or lactation.
All patients received transabdominal US, abdominal high resolution CT and contrast-enhanced ultrasonography (CEUS) before the cholecystectomy.
干预措施: Abdominal high resolution CT (Device)
