Abstract
Multi-detector row CT (MD-CT) induced revolutionary change in the CT diagnosis. MD-CT provides enormous information and novel post processing methods by workstation, which enables far more precise and detailed preoperative evaluation. Though spatial and time resolution of MD-CT are far better than these of any other diagnostic modalities, tissue resolution of MD-CT is inferior to that of endoscopic ultrasonography or MRI. Intravenous and/or biliary contrast medium would compensate for the defect and are useful to the diagnosis of gall bladder cancer. Detailed assessment of protruding lesion and asymmetric thickness of the wall in the gall bladder is important for the diagnosis of resectable and curative ss gall bladder cancer. Special attention should be paid for the co-existing flat or protruding lesion in acute cholecystitis and segmental-type adenomyomatosis.
