Overview
MRI is the modality of choice for assessment of hypothalamic, spleen, kidney, and other abdominal hamartomas. On MRI, hamartoma is characterized by a heterogeneous signal in T1 and high signal due to fat and cartilaginous components in T2.
MRI
- MRI is the modality of choice for assessment of hypothalamic, spleen, kidney, and other abdominal hamartomas.[1]
- T1: isointense to cerebral cortex
- T1 contrast: no contrast enhancement
- T2: iso to hyperintense to cerebral cortex, the higher the proportion of glial cells, the higher the T2 signal.
- MR spectroscopy
