Comparison of NaF PET-CT and Diffusion MRI in the Diagnosis of Bone Metastases (IMMETAOS)

Not Applicable

Completed

• Conditions: Cancer; Bone Metastasis
• Interventions: Device: PET-CT; Device: MRI

• Registration Number: NCT02876731
• Lead Sponsor: Institut Jean-Godinot

Brief Summary

Prospective, monocentric, comparative, non randomised

Primary objective :

- to compare the diagnostic accuracy of sodium fluoride PET-CT and MRI using the conventional block and diffusion sequence in the search for bone metastases

Secondary objectives :

* compare accuracy of MRI diffusion and conventional MRI

* explore the evolution of the results of the different types of imaging over time or under treatment for patients with repeated examinations at 6 months

Detailed Description

Prospective, monocentric, comparative, non randomised.

Organization of NaF PET-CT and MRI on the same day or within a 10 days period.

At 6 months :

* repeat both exams systematically if one of the initial tests showed a suspicious or doubtful abnormality

* final diagnosis by a committee of practitioners using the whole patient's file

Scheduled Project inclusion duration of 36 months (possible adaptation of duration in order to obtain the number of required patients)
