Brief Summary:
The purpose of this prospective study is to investigate the degree of association between the volume of important pain-relevant structures in the brain and the size of the areas of secondary hyperalgesia.

Condition or disease Intervention/treatment Phase
Pain Secondary Hyperalgesia Healthy Volunteers Magnetic Resonance Imaging Device: MRI-scan Not Applicable

Detailed Description:

The healthy study participants will be included from the cohort of a previous study (NCT02527395) where areas of secondary hyperalgesia, heat pain detection thresholds, pain during 1 min. thermal stimulation and test results from the Pain Catastrophizing Scale and the Hospital Anxiety and Depression Score will be retrieved. The study consists of 1 study day. The study day will be conducted at a maximum of 2 months and a minimum of 2 weeks after the completion of the previous study (NCT02527395).The results of the previous study (NCT02527395) will be blinded until all participants have completed the study day.

All study participants will complete a MRI-scan of the brain.

The MRI scans will be performed with a Siemens MAGNETOM Verio 3 tesla, with b17 software, and a 32-channel head coil. The MRI-scan sequence is as follows:

  • 3D Localiser
  • 3D T1 weighted iso
  • AX Diffusion tensor imaging
  • AX Epi resting state fMRI
  • AX Gre field map
  • AX Epi ASL
  • AX T2-weighted blade
  • AX T2-weighted flair
  • AX T2-weighted* Gre

Total MRI-scan time is estimated to approximately 40 minutes.

  2. White matter microstructure, evaluated by tract based spatial statistics, and size of the area area of secondary hyperalgesia, evaluated by cm2 [ Time Frame: 40 minutes ]
    By Diffusion Tensor Imaging to investigate the association between area of secondary hyperalgesia and white matter microstructure using tract based spatial statistics (TBSS).

  3. White matter microstructure, evaluated by tract based spatial statistics, and size of the area area of secondary hyperalgesia, evaluated by cm2 [ Time Frame: 40 minutes ]
    By Diffusion Tensor Imaging to conduct white-matter tractography to determine the connections between cortical and subcortical brain areas relevant for pain processing (Primary somatosensory cortex, anterior and mid Cingulate cortex, Basal ganglia (Putamen, Accumbens nucleus, and Globus pallidus), Insula, and the Cerebellum)


Other Outcome Measures:
  1. Volume of the nucleus caudatus, evaluated by mm3, and heat pain detection threshold, registered by degrees celsius. [ Time Frame: 40 minutes ]
    to investigate how close the volume of the Caudate nucleus of the right and left hemisphere is associated with the heat pain detection threshold.

  2. Volume of the nucleus caudatus, evaluated by mm3, and pain during 1 min. thermal stimulation, evaluated by maximum on the visual analog scale, 0-100mm. [ Time Frame: 40 minutes ]
    To investigate how close the volume of the Caudate nucleus of the right and left hemisphere is associated with the maximum visual analog score (0-100mm) during 1 min. thermal stimulation (45 degrees celsius) of the skin.

  3. Volume of the nucleus caudatus, evaluated by mm3, and pain during 1 min. thermal stimulation, evaluated by area-under-the curve of the visual analog scale, 0-100mm. [ Time Frame: 40 minutes ]
