Target follow-up duration
Target follow-up type
Description of intervention(s) / exposure
- Intravenous bolus injection of 125MBq of 64Cu-ATSM, followed by PET scanning of the brain for up to 90mins.
- Single timepoint
Intervention code [1] 315830 0
Early Detection / Screening
Comparator / control treatment
This observational study will use a cross-sectional, between-group design. A comparator group of individuals who are not affected by Friedreich ataxia, and matched for demographic characteristics, will undergo the same procedures, allowing for between-group statistical comparison with the clinical cohort.
Control group
Active

Outcomes
Primary outcome [1] 321701 0
Standardised Uptake Value Ratio (SUVR) of 64Cu-ATSM binding in the dentate nuclei relative to the cerebral cortex estimated from the reconstructed PET scan after SUV equilibrium.

Prospective
Statistical methods / analysis
- Standardised uptake value ratios (SUVR) of the regions-of-interest (dentate nuclei and brainstem) will be calculated relative to the cerebral cortex.
- Between-group statistical inference will be undertaken using independent samples t-tests (or equivalent non-parametric Mann-Whitney U in the case of non-normality in the data).
- Linear correlations between SUVR values and clinical severity (SARA) will be undertaken using Pearson correlations (or equivalent non-parametric Spearman correlations in the event of non-normality in the data).
