[F-18]NaF-PET for bone imaging

JRCT ID: jRCT2052230066

Registered date:08/07/2023

Basic Information

• Recruitment status: Pending
• Health condition(s) or Problem(s) studied: metastatic bone tumor
• Date of first enrollment: 31/07/2023
• Target sample size: 23
• Study type: Interventional
• Intervention(s): [F-18]NaF PET/CT, whole body MRI

Outcome(s)

• Primary Outcome: To verify that the diagnostic accuracy of the [F-18]NaF PET test for bone metastases exceeds the clinically required value (accuracy of bone scintigraphy).

Secondary Outcome

1) Sensitivity, specificity, positive predictive value, and negative predictive value of [F-18]NaF PET in the diagnosis of bone metastases.
2) Diagnostic performance (positive predictive value, sensitivity, specificity, positive predictive value, negative predictive value) of [F-18]NaF PET/CT examinations (including CT and fusion imaging).
3) Diagnostic performance (positive predictive value, sensitivity, specificity, positive predictive value, negative predictive value) of [F-18]NaF-PET for metastatic bone lesions in each site by classifying whole body bones into extremities (upper arm, forearm, femur, lower leg to foot), skull, ribs, sternum, clavicle, spine (CV, ThV, LV, sacrum to coccyx), and pelvis bones.
