Abstract
Gallbladder cancer is the most common cancer of the biliary tract with a high mortality rate. To improve its prognosis, early diagnosis and adequate surgical treatment are absolutely required. The intraluminal polypoid lesions, which detected with unenhanced computed tomography and focal asymmetric wall thickening are important signs to the differential diagnosis of neoplastic lesions. The multi-planer reconstruction imagings improve the accuracy of staging. For the diagnosis of the local extent of cancer, MDCT has an advantage to distinguish T2 lesions from more advanced lesions. The combination the size criteria and pattern of enhancement is useful for the diagnosis of possible spread to lymph nodes.
