The Role of Different Imaging Methods in the Diagnosis of Gallbladder Polyps

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.

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.

Inclusion Criteria:

• All patients with a gallbladder polypoid lesion visited our department, diagnosed by conventional transabdominal US.

Exclusion Criteria:

• Gallbladder polyp with a diameter less than 10 mm.
• Lesions highly suspected to be cancer due to visible metastasis.
• Allergy to contrast agents and cannot received CT or CEUS examination.
• Women in pregnancy or lactation.
