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
