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]
