Overview

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

MRI

  • 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
