The role of magnetic resonance imaging in evaluating migraine and the relationship between Corona and migraine cases

Abstract Introduction: Magnetic resonance imaging is indicated in case of suspected posterior fossa lesions or cerebrospinal fluid leakage. This study aims to study the symptoms and radiological signs of migraine on MRI. Methods and materials: A retrospective study was conducted on a group of patients visiting Al-Mouwasat Hospital with a history of headache in the period from 2021 to 2024. All patients underwent MRI as an investigation due to suspicion of migraine, totaling 1561 patients. Results: The location of the headache was found to be the frontal lobe 83%, the temporal lobe 32%, around the orbits 42%, the parietal lobe 20%, the occipital lobe 14%, and the cervical lobe 17%. Speaking about the continuation of migraine attacks for days, we found that the percentage of those who have daily migraines is 13%, those who have more than 4 months 18%, 4–8 months 26%, and 4–7 months 27%. Speaking about the cases in which radiological investigation is indicated, we found that the percentage of patients who have continued and prolonged the prodromal stage is 15%, the percentage of patients who have prolonged and severe clinical symptoms is 20%, the percentage of those who have the first appearance of migraine symptoms is 15%, the percentage of migraine without prodromes that required radiological investigation is 27%, the percentage of those who have migraine with loss of consciousness is 8%, the percentage of those who have complications is 5%, and those who have prodromes without Headache 10%, and speaking of the signs observed by MRI in migraine patients, we found that high-signal foci in the second time and the FLIR time were observed at a high rate of 92%. Conclusion: MRI is a suitable radiological method for evaluating migraine and can be used as an indicator for treatment and monitoring chronic cases.
