Overview
Neuroimaging is not necessary in patients with a clinical diagnosis of migraine. Head images such CT and MRI might be needed to rule out other suspected possible causes of headache. It is suggested to order a CT scan without contrast among patients with an unusual headache
CT And MRI
CT is indicated in patients with: [1] [2]
- Abnormal physical examination
- Increase of headache's frequency
- Poor coordination
- Focal neurologic signs
- Headache's awakening the patient at night[3][4]
- Atypical aura: sudden onset, lasting more than 1 hour, always at the same side and/or without visual symptoms
- Migraine attacks that begin after 50 years of age
CT is not indicated in:
- Patients with a diagnosis of migraine in accordance with the criteria for migraine.
- Differentiating a migraine from other primary headaches
