The Effects of the Female Hormones on Cerebral Perfusion

Several MRI scan modalities: MPRAGE (structural scan), arterial spin labeling (cerebral perfusion), resting state functional-MRI (fMRI, cerebral activity) and diffusion MRI (white matter diffusion and white matter tracts).

During MRI: heart rate, end-tidal carbon dioxide (CO2), respiratory rate and skin conductance

Blood sample after MRI-session: measurement of hematocrit, hemoglobin, estradiol, progesterone, follicle stimulation hormone and luteinizing hormone.

Measuring blood pressure before and after MRI-scan

Measuring body temperature before and after MRI-scan

Questionnaires at the start of the study on lifestyle. Additionally, a questionnaire before each scan session on the actual state of the volunteer (e.g. mood, caffeine consumption, alcohol, medication, etc.)
