68Ga-FAPI PET/CT Imaging for Diagnosis, Grading, and Efficacy Evaluation of Myelofibrosis.

Recruiting

• Conditions: Primary Myelofibrosis

• Registration Number: NCT06151119
• Lead Sponsor: The First Affiliated Hospital of Xiamen University

Brief Summary

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.

Detailed 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.
