Functional Study of the Hypothalamus in Magnetic Resonance Imaging (MRI) in Polycystic Ovary Syndrome (PCOS) (MRI-PCOS)
November 8, 2022 updated by: University Hospital, Lille
Functional Study of the Hypothalamus in High-resolution Magnetic Resonance Imaging (MRI) in Women With Polycystic Ovary Syndrome (PCOS): a Comparative Study
The aim to evaluate whether activation of the hypothalamic-pituitary-gonadal axis in PCOS is associated with transient microstructural and metabolic changes in the female hypothalamus using MRI approaches to assess water diffusion and measure proton magnetic resonance spectra.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the Apparent Diffusion Coefficient (ADC)
Time Frame: Baseline and 3 months after treatment start
|
The change in the ADC will be analyzed in healthy volunteers and PCOS women before starting the oral contraceptives, and next during the third sequence of treatment.
|
Baseline and 3 months after treatment start
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the metabolite concentrations
Time Frame: Baseline and 3 months after treatment start
|
The change in the metabolite concentrations will be analyzed in the two groups before starting the oral contraceptives, and next during the third sequence of treatment.
|
Baseline and 3 months after treatment start
|
Correlation coefficient (Spearman or Pearson) between the ADC and serum hormonal levels (FSH,luteinizing hormone,oestradiol, AMH)
Time Frame: Baseline and 3 months after treatment start
|
The correlation between ADC and hormonal levels in the two groups will be analysed before starting the contraceptive treatment and during the third processing sequence.
|
Baseline and 3 months after treatment start
|
Correlation coefficient (Spearman or Pearson) between the metabolite concentrations and serum hormonal levels (FSH, luteinizing hormone, oestradiol, AMH)
Time Frame: Baseline and 3 months after treatment start
|
The correlation between metabolite concentrations and hormonal levels in the two groups will be analysed before starting the contraceptive treatment and during the third processing sequence.
|
Baseline and 3 months after treatment start
|
Plasma GnRH concentration before and after treatment (PCOS patient and control group)
Time Frame: Baseline and 3 months after treatment start
|
Baseline and 3 months after treatment start
|
|
Correlation between brain metabolite concentrations and plasma GnRH concentration before and after contraception.
Time Frame: Baseline and 3 months after treatment start
|
Baseline and 3 months after treatment start
