On MRI, hepatic hemangioma is characterized by hypointensity on T1-weighted imaging and hyperintensity on T2-weighted imaging.^[1]

• Hemangiomas are diagnosed by a physical examination. In the case of deep or mixed lesions, a MRI scan may be performed.
• Occasionally, a hemangioma may occur with other rare conditions. Additional tests may be done for these syndromes.
• On MRI, hepatic hemangioma is characterized by:^[1]

• T1: Hypointense relative to liver parenchyma
• T2: Hyperintense relative to liver parenchyma
• Portal venous enhancement: Peripheral nodular enhancement
• Delayed enhancement: Lesion fills in the contrast
