Gallbladder cancer is more common in females and is generally believed to be associated with chronic stimulation from chronic cholecystitis and gallstones. On MRI, gallbladder cancer can be categorized into several types based on case classification and growth patterns: first, the infiltrative type; second, the nodular type; third, the mass-forming type; and fourth, the obstructive type. Regardless of the pathological type of gallbladder cancer, the tumor tissue appears as a heterogeneous low signal on T1 and a heterogeneous high signal on T2. After enhancement, the tumor shows heterogeneous enhancement. If there is invasion into the liver, the boundary with liver tissue is unclear. MRI has significant advantages in assessing invasion of adjacent organs and metastasis, and can provide great value for surgery or treatment planning.
