Purpose:
The aim of this study is to assess the diagnostic value of diffusion tensor magnetic resonance imaging (MRI) in the detection of brain microstructural changes in patients having migraine without aura.
Material And Methods:
Our prospective study included 33 patients having migraine without aura and 15 volunteers with matched age and sex, who underwent brain MRI with diffusion tensor imaging (DTI). The fractional anisotropy (FA) and mean diffusivity (MD) of selected grey and white matter regions on both sides were measured and correlated with the neurological clinical examination.
Results:
Significant differences were detected in MD values in the thalamus, globus pallidus, and hippocampus head on the right side of patients versus controls. Also, significant differences of the FA values were detected in the thalamus, globus pallidus, and hippocampus head on the right side of patients versus controls. Regarding the FA values of the same regions on the left side, a significant difference in the FA value was detected only in the hippocampus head. There was a statistically significant difference in the FA values on both sides of the white matter of the frontal lobes, posterior limbs of the internal capsules, and cerebellar hemispheres in patients compared to controls. There was a statistically significant difference in MD values in the white matter of both frontal lobes, posterior limb of the right internal capsule, and both cerebellar hemispheres in patients compared to controls.
Conclusions:
DTI can detect microstructural changes of the grey and white matter in patients having migraine without aura that could not be detected by conventional MRI.
Insights
Diffusion tensor imaging (DTI) detects subtle brain changes in migraine without aura patients. This advanced MRI technique reveals microstructural differences in grey and white matter not visible with conventional methods.
Area of Science:
- Neuroimaging
- Neurology
- Medical Physics
Background:
- Migraine without aura is a common neurological disorder.
- Conventional MRI often fails to detect underlying brain abnormalities in these patients.
- Understanding microstructural changes is crucial for diagnosis and treatment.
Purpose of the Study:
- To evaluate the diagnostic utility of diffusion tensor imaging (DTI) in identifying brain microstructural alterations in migraine without aura.
- To compare DTI-derived metrics between patients with migraine without aura and healthy controls.
Main Methods:
- Prospective study involving 33 migraine without aura patients and 15 controls.
- Brain MRI with diffusion tensor imaging (DTI) was performed on all participants.
- Fractional anisotropy (FA) and mean diffusivity (MD) were measured in grey and white matter regions and correlated with clinical findings.
Main Results:
- Significant differences in mean diffusivity (MD) and fractional anisotropy (FA) were observed in the right thalamus, globus pallidus, and hippocampus head.
- FA differences were also noted in the left hippocampus head, bilateral white matter (frontal lobes, internal capsules, cerebellar hemispheres).
- MD differences were found in bilateral white matter (frontal lobes, right internal capsule, cerebellar hemispheres).
Conclusions:
- Diffusion tensor imaging (DTI) effectively detects microstructural changes in both grey and white matter in patients with migraine without aura.
- These DTI-detectable changes are often missed by conventional MRI techniques.
- DTI shows promise as a sensitive diagnostic tool for migraine without aura.
