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][2][3]
- Very low, mainly homogeneous signal on both T1- and T2-weighted images[4]
- Foci of extramedullary hematopoiesis (EMH) involving the spine manifest as heterogeneous and predominantly hyperintense masses
- Foci of intracranial extramedullary hematopoiesis (EMH) manifest as masses of variable signal intensity[5]
