Do asymptomatic liver hemangiomas require MRI?

MRI is one of the most important tools for the diagnosis of hepatic hemangiomas, and can be used for both initial diagnosis and review. Hepatic hemangioma is the most common benign tumor of the liver. Hepatic hemangioma grows slowly and lacks specific clinical symptoms, and laboratory tests such as blood routine, liver function and tumor markers generally have no diagnostic value. Ultrasound is simple and easy to perform, widely used in the diagnosis and differentiation of hepatic hemangiomas, and is also the most common examination tool in follow-up. With the improvement and technology of CT and MRI, the diagnostic accuracy of hepatic hemangioma has been significantly improved, therefore, multiple examination methods are usually used to comprehensively evaluate and diagnose the condition. ①Abdominal ultrasonography is the first choice, which typically shows a well-defined hypoechoic or hyperechoic mass. ② Abdominal MRI and enhanced CT examination can assist in the diagnosis: MRI shows low signal or equal signal in T1WI, obvious high signal in T2WI, and centripetal enhancement of the tumor after enhancement; enhanced CT shows peripheral enhancement in arterial phase, and progressive centripetal filling in portal vein phase. The serum AFP value is within the normal reference value, or the dynamic observation shows a gradual decreasing trend. It is recommended to go to the regular hospital for diagnosis and treatment as prescribed by the doctor.
