Overview
To evaluate the diagnostic efficacy of 68Ga FAPI PET/CT in myelofibrosis and to identify fibrosis grades.
To evaluate the diagnostic efficacy of 68Ga FAPIPET/CT imaging in patients with myelofibrosis, compared with conventional CT.
Description
This study uses bone marrow biopsy as a gold standard or reference standard to evaluate the diagnostic efficacy (Sensitivity, Specificity, Positive prediction rate, Negative prediction rate) of 68Ga FAPI PET/CT in myelofibrosis and to identify fibrosis grades.

- Voluntarily sign informed consent.
- Willing and able to follow the research protocol;
- The subject must be able to lie on the scanning bed for 20 minutes;
Exclusion Criteria:
- Known allergic history to 68Ga FAPI or its excipients;
