Headache in a child?
Summary:
Recurrent, including migraine, without permanent neurologic deficit or signs of increased intracranial pressure = probably nothing
Headache with permanent neurologic deficit or signs of increased intracranial pressure = MRI without (and maybe with contrast), CT, if MRI not available.
Abrupt onset, thunderclap, concern for vascular rupture = CT head without contrast (if subarachnoid, add CTA and maybe catheter angiography if available)

Radiology is a very large and ever changing field and this post is to help your provider. When combined with a thorough history and physical exam, this information can be very useful. Your provider is best suited to answer specific questions regarding this post.
A provider is usually a Nurse Practitioner, Physician Assistant or Medical Doctor.
