As ultrasound (US) is a simple and less invasive modality, it is widely used for mass screening. Both gallbladder polyps and thickened wall are common findings. As the diagnostic accuracy of US depends on the skill and knowledge of the sonographer, sonographers should master the standard scanning method and learn characteristic findings for the differential diagnosis. First, we explain the important findings for the differential diagnosis of gallbladder tumors and thickened wall, citing the categorized criteria for US cancer screening of the Japanese Society of Gastroenterological Cancer Screening. Second, we highlight indirect US findings such as gallbladder distension and debris as useful findings for detecting small gallbladder carcinomas and occult lesions of the pancreatobiliary tract.
