NCT06851143

Brief Summary

This is a diagnostic pilot study that recruited 25 normal volunteers and 40 patients with dysfunctional brain diseases and performed 18F-DPA-714 PET/MR imaging to evaluate the correlation between the multimodal imaging features of dysfunctional brain diseases, to explore the potential pathological mechanisms of neuroimmune activation, and to further analyse the value of PET/MR-based multimodal imaging in the diagnosis and differential diagnosis of dysfunctional brain diseases. and further analyse the diagnostic and differential diagnostic value of PET/MR-based multimodal imaging in dysfunctional brain diseases.

Outcome Measures

Primary Outcomes (1)

  • Maximum Standardized uptake value (SUVmax)

    1 day from injection of the tracer

Study Arms (1)

Comparative study of different groups

OTHER

This study is planned to include approximately 25 normal volunteers and 40 patients with dysfunctional brain diseases. The screened subjects will undergo multimodal imaging data acquisition using integrated PET/MR (GE Signa). The SUV ratio (SUVR) of each brain region will be obtained using the cerebellum as a reference, and differences in \[18F\]DPA-714 uptake between patients and normal controls will be compared using voxel-based imaging analysis. PCA-based analysis of the distribution pattern of TSPO radioabnormalities in different types of patients. Pearson correlation-based analysis of the correlation between neuroimmune activation and structural and functional parameters.

Diagnostic Test: 18F-DPA-714 PET/MR scan

Interventions

Saline intravenous solution of 18F-DPA-714 administered at 0.1 mCi/kg by bodyweight

Comparative study of different groups
