Abstract: In February 2022, the world′s first gallbladder reporting and data system (GB-RADS) for the assessment of gallbladder wall thickening on ultrasonography was published in the form of an international expert consensus. The GB-RADS system classifies gallbladder wall thickening into six levels (GB-RADS 0?5), with gradually increasing risk of malignancy. It is mainly based on the following features: symmetry and extent (focal versus circumferential) of involvement, layered appearance, intramural features (including intramural cysts and echogenic foci), and interface with the liver. The proposed system is important for the standardized diagnosis and treatment of gallbladder diseases. The authors interpret the consensus, introduce the evaluation points and classification standards, and suggest the future applications and research directions.
