Abstract    There are many imaging methods in detecting gallbladder carcinoma. Ultrasonography is the most common imaging method now, but the applications of CT and MRI are increased gradually and shown very important in diagnosing gallbladder carcinoma in clinical practice. 18F-FDG PET-CT has very high specificity and can be used in diagnosing difficult cases. It is not difficult for diagnosing typical gallbladder carcinoma, but it is not easy to diagnose early stage of gallbladder carcinoma. The applications of CDFI, contrast-enhanced ultrasound, dynamic CT and MRI scanning, DWIBS technique and 18F-FDG PET-CT will hopefully increase correct diagnosing level for early stage of gallbladder carcinoma. CT and MRI are better in demonstrating invasion of near structures and lymph node involvement due to gallbladder carcinoma. But lymph node involvement can easily get missed diagnosis just based on the size of lymph node. The shortages would be improved by 18F-FDG PET-CT and DWIBS technique.
