Overview
Other diagnostic studies for myelofibrosis include genetic testing, which demonstrates JAK2V617F mutation, hybrid imaging, which demonstrates increased uptake of the radionuclides by the extramedullary hematopoietic foci, and bone scintigraphy and positron emission tomography (PET), both of which demonstrate fibrosis.
Other Diagnostic Studies
Genetic Testing
- Allele specific polymerase chain reaction (AS-PCR) is used to amplify the exon 12 of Janus kinase 2 (JAK2) gene which harbours V617F mutation.[1][2]
Bone Scintigraphy
- Bone scintigraphy will demonstrate increased tracer uptake.[3][4]
Positron Emission Tomography (PET)
- Positron emission tomography (PET) is a reliable and convenient technique to assess hematopoietic activity in the bone marrow and can be an used as an alternate to bone scintigraphy.[3][5]
Hybrid Imaging
- Hybrid imaging involves the use of two radionuclides, technetium 99m ([99m] Tc) and indium 111-chloride ([111] In-Cl3), coupled with single-photon emission tomography/computed tomography (SPECT/CT).[6]
- It can serve as an alternative noninvasive method for the screening of the whole-body marrow and also to assess the impact of targeted therapies.
