BIOMIGA: Results From Magnetic Resonance Imaging

The projects comprising in the multicenter BIOMIGA project have been preregistered earlier with ID NTC04503083 at clinicaltrials.gov. Here the imaging subproject within the overall BIOMIGA aims is specified. The hypotheses for this subproject of the magnetic resonance imaging part is based on hypotheses generating analyses of the data from one site (Hamburg, Germany) of this three-center study. At all three sites healthy controls and migraine patients underwent identical protocols with 3 types of magnetic resonance imaging including structural scans (MPRAGE), resting-state functional magnetic resonance imaging (rs-fMRI) as well as arterial spin labeling (ASL) with matched protocols across sites. Data was acquired before CGRP-antibody administration (day 1) and 12 weeks afterwards (day 2). We analyzed the data from one site (Hamburg, Germany) as hypotheses generating, published these data as a poster and aim to validate our results with the not-yet analyzed data from the two other sites (Pavia, Italy and Barcelona, Spain).
