Overview
MRI may be helpful in the diagnosis of myelofibrosis. Findings on MRI suggestive of myelofibrosis include diffuse decrease in bone marrow signal intensity.
MRI
- MRI may be helpful in the diagnosis of myelofibrosis and can be useful in evaluating the stage and the progression of disease.
- Findings on MRI suggestive of myelofibrosis include:
- Diffuse decrease in bone marrow signal intensity.[1]
- Very low, mainly homogeneous signal on both T1- and T2-weighted images[2]
- Foci of extramedullary hematopoiesis involving the spine manifest as heterogeneous and predominantly hyperintense masses
- Foci of intracranial extramedullary hematopoiesis manifest as masses of variable signal intensity[3]
